So in discussions with Kolari, they mentioned they'd done a "naked sensor" conversion, so just taking the away the hot mirror and not replacing it with the thinner quartz filter for full-spectrum or two-spectrum, on an a7rII that was very successful. I asked about downsides, like cleaning, IBIS, etc., and this was the response.

"It's still possible to clean the sensor like normal, and IBIS still works. The biggest drawback is that if you scratch the sensor, you scratch the actual sensor, not a protective filter."

I'm pretty careful with my cleanings and have never scratched the protective filter, so I don't...Show more →

Sometime lurker, first time poster here, but I've been following the thin filter threads for a while, and am intrigued to see someone else have the same idea as me (thought maybe no one had given it any thought because a FS conversion would just be too impractical for standard visible spectrum photography).

Right now I'm still using an NEX, but been putting funds aside for an A7x to use with legacy glass, and am seriously considering this route (FS or TS conversion). When I contacted Kolari about filter thickness a month or so back, they said what I guess they must have told you, that their FS and TS filters come in two thickness for the A7, a standard and a thin version like their usual thin filter mod (though oddly they don't make this clear anywhere on the site). Didn't go into much more detail than that...

I'd be surprised if it weren't possible to make a full spectrum filter thinner than a hot mirror though—surely the minimum thickness of a UV/IR cutting filter is necessarily greater?

Anyway, another thing I've been considering, and trying to find answers for, is whether the two spectrum or full spectrum would offer better results for vis-spectrum stuff. You might have seen the material they have on their site, where you can see the transmission curves of their TS filter + lens hot mirror vs FS + hot mirror—the latter lets in significantly more blue/near-UV (gentle cut from 400nm) than the former (steep cut at 425nm).

Presumably, getting the best results in terms of white balance and colour accuracy is going to mean replicating the spectral response of the stock filter as best as possible, but different cameras' hot mirrors have different UV cutoffs, and it's hard to find information on specific models...

Welcome amailmx!

My own personal impression: I have looked at quite a few full spectrum mods and the variants, which were then attempted to be shot as normal cameras. These are the samples. They never looked right to me.

That doesn't mean they might not give you a look you really like.

It doesn't even mean they never look right, as there may be better re-corrections. Theoretically with the right external IR cut, like an STC, you should be able to get "right back" to near Sony AWB. STC are new IR filters, and I have not seen anyone try them on a full spectrum.

I'm not interested myself because I don't want to have a bunch a filters to fumble with.

As far as best color accuracy potential, I guess the question is how the Sony engine might limit a better IR cut than they have. I don't think it does. Kolari v1 is S8612, which is supposed to have the best curve there is, though it corrodes. The Sony was fine with it, I thought. Better than v2, which is another glass. The STC is specifically designed to replicate Sony AWB, is what I thought I heard from Sam.

Also, I think if somebody (not you) is after edge performance and don't mind external filters, they should study that big active thread in the Sony forum on external filters.

Thanks uhoh. I guess it depends on personal needs/preferences.

As a hobbyist, and with my typical subject matter, I don't really need critical accuracy, and I might also be in the minority that quite enjoys the post processing side of things—or at least, I'm not too fussed if I have to spend a little extra time tweaking WB (far more within my comfort zone than shimming lenses—I'm not the most handy person). I've seen a few people shooting full spectrum cameras with UV/IR filters for vis-spectrum work, and they seem to be reasonably happy with results; I suspect it would be good enough for me. Plus, I've sort of always wanted to try a bit of IR stuff too...

Others, I'm sure, place more value on accuracy, or not having to spend to much time in post, or faff around with external filters in your case!

I'd not heard of the STC one, but thanks for mentioning it. The transmission curve looks pretty good, nice sharp cut just about bang on 400nm, and they seem to offer a few different variations for the IR cut. I'll have a look around see if I can find anyone that's used one.

I suppose that a Twin Spectrum filter will be better than a Full spectrum for colour accuracy, when taking pictures for normal light rendition ( i.e with a hot mirror filter on the lens). At least, it seems so by the samples on their website.
Nice to see that Kolari offers now FS and TS mods with the option of a super thin filter. When I asked them, maybe a year or more ago, they told me that there was a only a standard thickness available for these conversions
As a side note, searching more convenient places for European users, maybe some of you know DSLR Astro-Tec in Germany. Although specialized in astro conversions, they do also IR and Full Spectrum. What I don't know is the thickness of the clear glass employed in their FS conversion, if it's AR coated and, importantly, if they can remove the last sheet of glass on Sonys ( which is very unlikely, but you never know ).
I'll e-mail them for more details.

You got more information out of them than I did about the full-spectrum and two-spectrum conversions. I didn't know there was a thicker option. They just told me they were as thin as the Sony v2 conversion filter.

I think it should be possible to get a quartz filter with the same optical thickness as the v4, but I'm hardly an expert in the matter.

Nearly all of the hot-mirror filters do a better job cutting out the IR spectrum than the UV spectrum. The one Charlie mentions looks good, but only has 58 and 77mm filter sizes available and are nearly 40% more than the comparable Kolari and MaxMax filters. I may pick up one if the thicker Kolari filter has problems with my widest lens, since it is a 58mm thread, but otherwise I don't think it'll be a problem to work the UV filters I already have on my lenses into the stack.

My feeling on color is this: No conversion is going to be an exact match, be it hot mirror over the sensor or over the lens, so that's something we'd have to deal with either way. Personally, the RAWs I've seen from MaxMax filters (and, given the curves, I'd say his CC1's are basically the same as Kolari's) with UV filters are better than what I get out of my a7 with the v2 mod, and better than what Charlie's getting with the v4.

And it's not like getting the naked sensor conversion has to be permanent. If they come up with a thinner two-spectrum filter, I can always send it back and have it installed. I'm sure Kolari wouldn't turn down the business when a third of the work is already done.

I had exposure comp on the UT there, and reshot it, but it was snowing a little in the sun:

The UT seems well ahead again with the 28 cron all the way. I'll get some more samples up soon, but here is a remarkable shot. Mild editing.

Note the house in the corner at F/4.

I also shot the CV 35/1.4, which should be interesting at f/4.

The little CV 35/1.4 Nokton is more complex than the Cron at F4. There are no charts for it, but I'd bet money there is quite a wave in the outer mid-zone. The difference I see in the files---and anyone can correct me here---is the outer mid zone shows more even on the UT.

ZM18

UT_ZM18_f8 by unoh7, on Flickr

Very subtle differences in these lenses V2 vs UT. The oringal A7 EVF, for me, is very tough to precisely duplicate focus. Just a tiny variation will make one lens stronger on the edge than the other if they are already really close. So I must study the whole images to be sure there are not other parts which are obviously sharper. The ZM18 is superior on the UT, I believe, but it's not like the ZM35/2, 28cron, or CV 35/2.5, where it's plain. I've got the files out to some other eyes, to get check that idea. The Z18 ray angle is 40 on the edge which is more than the 33 of the ZM35, so why would we not see a more dramatic difference? CV 21 likewise. One difference is both of those ultra-wides do drop alot in sharpness as you reach the edge, on film.

M-Rokkor 40/2

UT_40cron_WO by unoh7, on Flickr

The 40/2 is very slightly better in the corners WO on the UT, is my impression so far. WB comes in warm so in the shots above I'm editing to see how hard it is to get them cooler.

The lower left corners from the basic test frame above without edits:

V2_40cron_WOcrop by unoh7, on Flickr

UT_40cron_WOcrop by unoh7, on Flickr

On the M9, the 40/2 at F8 is quite the blazing devil. Striking sharpness. I don't have the conditions yet to see if either mod can do that, but I was trying:

Below you get an idea of what it can do on the M9 stopped down:

L1053200 by unoh7, on Flickr

and the ZM18

L1055181-2 by unoh7, F/9.5ish

The last shot is "easier" than the ZM shot at the start of the post, as the right corner is so close. Shortly I will drag the M9 up on my testing vantage:

OK, A7.UT vs M9 with ZM 35/2 Biogon.

I'll start with F/5.6. They are pretty close, so focus variation is an issue.

Let's check the centers:

Now above, the M9 is backed a tiny smidge off my infinity stop, as in all these, as the corner was a tiny bit better in that one. The A7 was better when I thought I had center focus.

Con't

The ZM35 is very even across the frame and quite sharp out to the edge, but the deep corner is not at the level of the rest. This is a known attribute. Let's try F/8:

M9_ZM35-2_F8 by unoh7, on Flickr

UT_ZM35-2_F8R by unoh7, on Flickr

For myself, I like to follow the mid-frame out to the edge, and doing that, I think the UT is just a little weaker, however, it has a real strong center here, but M9 is strong too:

M9_ZM35-2_F8center by unoh7, on Flickr

UT_ZM35-2_F8center-3 by unoh7, on Flickr
I think in this case, looking at that white truck, the M9 is stronger in the center.

Edges have what always tells: trees at 2 miles away.

M9_ZM35-2_F8edge by unoh7, on Flickr
now the telling thing is those aspen near the edge, just a small clump on the M9, bottom far right, and a different larger stand on the UT higher up bar also far right. This is not a corner, but well below. M9 has it, no?

UT_ZM35-2_F8edge by unoh7, on Flickr
To my eye at this hour, the M9 is still better.
Corners?

M9_ZM35-2_F8crop by unoh7, on Flickr

UT_ZM35-2_F8R by unoh7, on Flickr

Fulls of the whole image are on flickr. This time I wore glasses and stopped using the Diopter. Still EVF focus is a tiny bit mushy. I refocused each shot, which was maybe not the best idea. But I tried very hard to be consistent. To much noise in the fully magged EVF on the older A7 for my eyes. But the whole images should tell much of the story in spite of that. It's pretty close.

I say the M9 is 1/2 stop ahead still at F/8

In a daylight landscape I would use F/11 on both if I wanted the best edges and corners.

Now, this lens was further ahead on the M240 vs V2 in Kasson's tests. So I think it' s gotten much closer. But we can't make the claim which I think Sam can with that ZM21/4.5: that his A7rii is out-performing the Leicas. We can say this is the closest an A7(original version) has ever gotten, probably

So that leaves WB, which I did not try to even out here. Derek has taken the plunge and we know his style very well, so I think it's going to be really interesting to see that "sebboh look" on the UT

Well...maybe there is a serious bar we test against, yet:

M9_28cron_F28 by unoh7, F/2.8, no less.

I'll see if I can match that with any focus on the UT. 28 Summicron on M9 is no joke. Seeing such a shot I gave up on the stock Sony in January 2014. BTW all M9 shots with profiles disabled.

Sry I caught the exp comp right after this, but I think it still tells the story.

Which is: 28 cron is stronger on the edge at F/2.8 than the Biogon (we knew that), and the M9 is about the same amount better, or maybe just a tad more better

Frankly I think it also says: the edge is a very good meter. Perhaps less variables than a corner.

Thanks for more great and informative posts.
My five cents : M9 is 18mp and A7 is 24, so I’d expect that the Sony must be a bit better in the centre at all apertures. Your pictures, to my eyes, seem to confirm this. In the corners, unlike you, I don’t see the M9 being any better. To me it’s a so close shave that focus accuracy may play a role here, but I assume that you were very careful in this matter.
That is concerning sharpness, Color is another question and obviously the UT photos have a strong reddish cast. It may be only a question of making a custom profile to get a natural color balance, but it might be also that IR is passing through that ultra thin filter. Couldn’t you post some pictures with black synthetic fabrics in them ? ( for instance, yourself wearing a black tuxedo

i don't know about creating a custom profile yet, but i took the liberty of just doing a simple wb correction to charlie's photos (i assumed the snow was white and used the eyedropper in LR).

These are very helpful Derek. The 40 Rokkor and the CV 35 look pretty good probably about as good as can be expected from these lenses. The CV 21 still shows some colour shift and the ZM 18 still shows a bit of smearing in the bottom right corner. All in all, however, these look pretty nice. Still I don't know if these show the mod would be worth it, but they give hope. I suppose that will be depend on a very individual decision.

the color shift in the cv 21 and zm 18 is purely due to the sensor/lens interactions not the sensor coverglass. it looks basically the same with a stock a7 or a v2 kolari conversion and it goes away if you have the a7rii with it's backside illuminated sensor. this is what corner fix and the flatfield plugin for LR will fix.

here's the same cv 21 shot with charlie's v2 a7:
http://c2.staticflickr.com/4/3806/32398453753_1594c977f4_o.jpg
color shift actually looks worse but, i'm betting that's just down to a non exact WB match from the random area of snow i chose to set WB from.

Steve: for me the A7 without some sort of mod is worthless. You call it personal. I call it a matter of priorities. If M/LTM is your priority and you also shoot an M body, a mod is simply rational. I hardly used the A7 without it and was disappointed when I did. I liked the V1 pretty well. V3 did not like. V2 I don't like as well as V1 but it's quite usable. This one, for me the jury is out. I like those cron shots fine. But 30 minutes later I shot some I thought really had some WB I could not deal with.

But I also had M9:

M9orUT? by unoh7, on Flickr

Now I'm thinking well, there is something there, but maybe a good color profile could handle it. Sort of a magenta saturation in the cupboards? I would have to figure out some way to tame that, but it might be easy. For those two, I left the M9 WB alone, but I had to push it. Then I did some mild tweaks on the UT to match. I'm not a fan of either WB there, especially the wall, but what it tells me is it is not a huge outlier, as I thought. M9 had problems too.

I tried to be careful, but one point of putting up center/corner/side is so any viewer can check, or just use the whole image. Under no circumstances should anybody take focus accuracy for granted in my shots. But a good look at the full should at least tell you where the focus is, I hope, assuming I did not pass it altogether.

I think I will try something different next time. I will just go past infinity a bit, shot one, and then come back bit by bit. M9 seems pretty good with 28 cron, so I will shoot the A7 shots like that. I should send the whole rig to Fred as he would probably knock it right out. Poor man has no M though. If somebody had a 240 and various wides, please PM me, as the whole idea of this camera is to test against M, and we want to share it. Wait, they are giving those 240s away now......

I would love to see the A7 beat the M9. That's the whole idea. I just don't. However, I'm very happy to be shown the A7 is better. Would not be the first time I was incorrect. Most of the knowledge i have is pursuing a belief and finding it was wrong. I thought the stock A7r was going to be great with M, in November, 2013. Many said I was crazy, but they did not have the proof.

We had a giant war over that here, and I went on flickr on got permission to post A7r and A7 with all sorts of M glass. But nobody did the proper infinity tests of course, they just shot fast with central subjects mostly, so my naive belief died a long and anguished death

The very fact you think the A7 is winning is awesome. I don't assume you are wrong.

Don't assume that I'm right either

I didn’t mean exactly that the A7 wins over the M9, but 24 vs 18Mp gives beforehand some advantage to the Sony. The fact that the corners are so close tell us that the M9 is still a bit better corrected for smearing. If not, the A7 would win in the corners too.

For me, the simplest meter is to start at the center and then move straight out to the edge, if possible. That's why prefer flat shots, though I making making both. Where I see the difference most clearly is the fall off at the far edge, following the distant tree line. For the corners, an exactly similar frame would make it easier to tell. You look at one tree but it's closer to the corner in one than the other.

But the cameras maybe are pretty close. Which is great.

As to 18 v 24mp. Just shows M9 at 18mp is shooting pretty well for a 2009 design At base ISO the full size images are strong enough to quiet my M10 lust.

I just broke down and ordered an X-Rite color checker. I will make camera profiles next week using the adobe software. Then we will get a more clear picture to see if the WB issues are manageable.

Yes, I should already own one and have anticipated the issue.
