Cool, I just found that info, too. Length is about identical, and the OM is a little lighter and skinnier. OM looks to be at least $100 more. Looks like a cool option.

The Ultron 28 is a modern retro-focus design so seems to perform closer to it's film specs than many other wide RFs. It's also likely to do well on the n-7

here are some interesting discussions on the lens

It seems some of the old hands, Puts and Abrahamsson, are big fans of the lens.

As a result of the dawning revelation that it is the AA (and perhaps other) filter thickness in front of the sensor which causes some lenses to go all soft and mushy on the edges and corners, I'm hoping that retrofocus design prices go through the roof and non-retro designs plummet.

I'd like to get a few more truly excellent lenses for my GXR at cheaper prices.

500 bucks f/2 RF, what's not to like? I've got something like 8 CVs and every one is excellent---why would this be a bad lens?

hopefully we will have someone who owns one show us some nice shots to put your mind at ease

Meanwhile let's see some pretty shots with those canons !

I've got 5 CVs, and I don't think I'd call any of them excellent on NEX, except maybe the 85/3.5. Even the 50/1.5 isn't as sharp as is should be at the perimeter, considering it's made for a 135 sensor (it has a little color shift, too.)

According to those linked pics, the Ultron 28/2 has pretty bad color shift on the 5, and it's still obvious on the 5N. The resolution doesn't look great at the perimeter, either, but it's hard to tell in the relatively small pics.

I'm still waiting on my new Canon lenses to arrive, but I'd bet that my cheapie FDn 28/2.8 from high school is considerably sharper than that Ultron. I think the Summicron is the only 28 rangefinder lens I'd consider on NEX.

And not Contax G 28? Super performance at a low price. Sure, the adapter is not a perfect solution for focusing, but is the annoyance worth giving up the package?

I'm still in doubt about how annoying it really is, never had the chanche to try it. I see a lot of people dumping their contax g lenses because of it.
Seen so many NEX shots the past week and to me the contax G28 is one of the most appealing lenses. Small, nice rendering and not expensive.

Still don't know yet which way to go. I love the look of the photos taken with a leica X1. The lens seems to be really excellent. If it wasn't for that quirky body I already bought one of those.

It was a pump and dump decision for me

No doubt the lens is very nice, but to me the user experience is very important. I couldn't enjoy myself with that adapter. I returned the adapter and sold the lens.

- not small
- not light
- color shift
- doesn't look great on 5N (so far)
- $500
- SLR lenses available at nearly identical weight and size, likely with better IQ (TBD), for less than half the price

Douglas,
Which 5 CV lenses do you have, and in your opinion what are "excellent" lenses in the same/similar focal lengths on the 5N? I'm not giving you a hard time, just curious about your thoughts.


Did you pick up a 28/2 or are you sticking with the 28/2.8?

i don't really notice the adapter anymore when using my contax g.

CV 15/4.5, 35/1.4, 50/2.5, 50/1.5, and 85/3.5. Technically, I'd say the 35/1.4 is the worst, the rest are acceptable, but none of them blow me away. The 50/1.5 is very good in the center, but the edges aren't as good as they should be. The 85/3.5 does have pretty even sharpness across the frame, which should be expected, but it isn't incredible sharpness or anything.

I'd say, at this point, of the 35mm rangefinder lenses that I've tried, the ZM 35/2 performs the best overall, but it still has some color shift on the 5N, and it makes me wonder how much sharpness I'm loosing from the camera's filter arrangement. The hardest lens for me to loose will be the ZM 50/1.5, because I'm getting into the "vibe" of it, it is a great size, and it actually has pretty good edge sharpness when stopped down a bit (better than the Nokton.)

I ordered the FD 17/4, 28/2, 50/1.4, 55/1.2 (both FL and FD versions,) and the 85/1.8, but I haven't received them yet. I must say though, in informal testing, the FDn 28/2.8 and 50/1.8 that I've had since high school perform as well as any rangefinder lens I've used, and you can get each of them for less than $30. So it seems to be a matter of cost vs. size.

I'm not sure I've got it in me to do some exhaustive test to post online, once these FD lenses arrive, because I'll get an idea pretty quickly whether they outperform my rangefinder lenses. If they do, I'll probably sacrifice the size of the nice little rangefinder lenses. My biggest concern is with the FD 17/4, because it is SO much bigger than my current options in that range, so it'll have to be pretty darn good for me to switch.

I could end up keeping the CV 15/4.5 and ZM 50/1.5, and just replacing my various 35mm lenses with the FD 28/2 (and I'll just return the rest of the FD lenses.)

p.s. I probably shouldn't speak too badly about rangefinder glass, since I could have 10 of them up for sale soon. we'll see...

Douglas, have you been using the ZM 50/1.5 for portraits? I'm really curious about this lens.

- SLR lenses available at nearly identical weight and size, likely with better IQ (TBD), for less than half the price

Time and time again there are people making the claim that SLR lenses (especially older OM, FD or AiS lenses) are likely as good if not better than RF lenses.

In every direct comparison I've ever seen (please show me otherwise) RF lenses are easily sharper and have higher contrast than SLR equivalents. It does not matter whether it is Leica M lenses, the Zeiss Biogons or CV lenses.

Partly, of course, it is because they are more modern than the old OM or FD lenses, partly because there is hardly ever any money spared in the design for M lenses, and the other RF lenses, if they are going to compete, have to be good, and partly because the design does not have to accommodate a mirror box.

I have nothing against OM lenses, I have plenty of them: 21/3.5, 24/2.8, 28/2, 50/1.8, 85/2 and use them on my 5DII, and they are very good and very good value, but in close comparison, they do not compete with any of my Leica M lenses or the few CV lenses I own, either in resolution or in contrast. I shoot only black and white so care little about their colour qualities.

this is probably true on film, however on the NEX i've seen a lot of weak performance from rangefinder lenses. i would be very surprised if there were not several old 35mm slr lenses that could outperform my contax g 35/2 on the NEX for example and from everything i've seen that lens outperforms the cv 35/1.4 at all shared apertures on the NEX.

I'll be very curious to see how the 17/f4 performs. I don't have any experience with SLR WA primes, but the CV 15/4.5 is at least as good as my mid-grade WA SLR zooms (Sony Zeiss 16-80 & Sigma 10-20). And as you mentioned, it's much, much smaller, and with the Hawks, it focuses much, much closer.

My comment was not a blanket statement, if you're following the conversation you'll notice I was talking specifically about the Ultron 28 on the NEX 5N, based on the samples seen so far and with "TBD" in regards to the OM 28/2 and FDn 28/2 quality.

Making blanket statements about lens performance on the NEX seems like a sure way to be wrong most of the time



Douglas, If you decide to part ways with the Nokton 50 I may want to give it a shot!

exactly, don't you think the RF trashing should wait for a direct comparison? Your pro SLR zealotry is a bit premature.

I very much doubt any of these SLR 28s will out perform the ultron--but since I don't really know I can wait. The ultron is such a natural choice for the nex, the harsh emotional objections puzzle me.

Jacob: it doesn't look good? You can't be refering to the how the lens actually looks, right? In that catagory the ultron wins hands down

As to size; your CV 35/1.2 is heftier SLR, but even that lens is smaller on the camera than any SLR setup I have, except the konica 40/1.8 which is still thicker, but way lighter obviously.

Anyway I'm not sure why the ultron is such a controversial suggestion, but again, we'll see soon enough how it does.

Speaking for myself, I would try one before going SLR---and if it was no good, I would probably just get a sony 24/1.8

That's after shooting a few thousand shots with SLR glass on the nex, if experience counts at all.

No, no, the Ultron is beautiful looking, I meant that the quality of the sample photos didn't look great, not bad either. For my needs, if a less expensive lens can match it that's the way I go. I don't think the Ultron is a controversial suggestion, from the few samples on the NEX it isn't screaming 'buy me!' to me, that's all. I have OM lenses on the NEX and the handling is fine for when I need them. All my other low light lenses are huge monsters that live on my 5D.

For example, I would much rather save the $300 and invest it toward, say the Nokton 50 that Douglas will soon wave goodbye to In all honesty, I don't know if I've seen enough of that lens on the NEX either to really know I want it, despite it's excellent rep in the Leica mount world.


Well, I did shoot some photos today, time for a quick run through LR...
