As to Max bailing on the A7R


He isn't actually bailing, we have a terminology problem here. You cannot bail on something you do not have. He is skipping it, although that sounds much less interesting, even if it is the truth.

Is it better to wrong and interesting, or right and boring?

I see you actually fixed the link so we can now see what you were talking about - and you not only enlarged it to your 11x test, but you are looking at the green-white transition!

OK... I get it. The Sony A7r uses the same sensor technology (Sony) as the Nikon D800 and has the same DXO scores (95).

The problem is the lenses.

The A7 system, by using adapters, gives you several lens options and a wickedly small camera body. This is great.

But let's get real for a minute. The lens options are a problem. The ultra wides have serious issues.

Compare to the larger sized D800. The DXO scores are the same except the Nikon lenses actually work with the D800, including everything... starting with the 14-24 and ending with the 800mm.

I'd love for the A7

Ahm, the same lenses that work with the D800 also work with the A7r. There is no lens that works with the D800 that would not work with the A7r. But on the A7r you also get a wide variety of lenses that also work great on the A7r that you can not use on the D800. Plus it is way better for manual focus. So, only because some wide angle rangefinder lenses do not work well to dismiss the camera is something I can not really understand, at least not on the alt forum

What exactly are you comparing here? You note that a Nikon camera works well with first party lenses. Ok... You then note that the new Sony cameras apparently don't work well with adapted ultrawides. Presumably you are talking about rangefinder lenses or others that cannot be used on a Nikon F-mount camera at all, which makes this an odd comparison.

Early indications are that native FE lenses largely avoid the shading and smearing issues seen with a lot of adapted rangefinder lenses. The real lens "issue" is that the native lineup is currently extremely sparse. As with any new system it will take a couple years to expand the lineup of native lenses.

I'd love for the A7 (A7r) to take over. Just give me lenses that don't have issues.

+1 And lets compare apples with apples. How does the A7(R) with with ultrawides other than RF? Wonderfully. The Olympus OM 21/3.5 works great! My Zeiss 15/2.8 and 21/2.8 Distagons also work great. There appear to be several Nikkor's, Canon FDs, that also work great down to 20mm. Yeah, it might suck for the Leica RF user but there are several options out there until Sony and Zeiss expand their lens offerings.

RF ultra wides have an issue. On the Canon forum there are good reports with TS lenses etc... and I am sure a host of other lenses will work fine as well.

This is a typical internet phenomena..take a problem that exists with a few lenses and then widen it to include all ultra wides, and then treat it as fact.

Reports indicate the 14-24 works quite nicely on the A7r so I don't think you can really fault the A7(r) any more than you could the D800 for issues with ultra, should one try to use a number of RF wides on that camera.

Its just all and all silly to try to blame Sony for making a camera that doesn't work with various 3rd party glass. Sure it would be nice if it works with great with a bunch of M wides, VC's in particular because they are a nice size and reasonable cost.

If you want to use the A7 with Nikon glass, sans AF it seems to work great, just like a smaller D800e. Only "issue" I guess is people don't want to use big SLR glass on a tiny camera....

What is Sony to do though ? Hold off on the camera until they have 10+ native lenses ?

I have no doubt Sony will have a nice ultra wide zoom out, and it will perform quite nicely, it will be expensive, and it will be big and bulky. Same can be said for a bunch of focal lengths down the road.

Then the arguments of the Nikon have more focal length options effectively are negated, though I think plenty still won't be happy because they want to use RF glass, which still is going to have issues.

Its like wanting a 2 seat sports car and then complaining it doesn't do well off road or for hauling groceries/kids around town.

A7(r) has some nice features and brings the camera body size down, but it just appears its not the holy grail as far as bringing the overall rig size down to where some would like it.

Something like a 400 gram A7 sized FF 36meg body, which could also provide great results with ultra small/light RF glass in wider focal lengths just hasn't arrived yet

Damn, I just found the 11:1 button in Lightroom (who even knew it was there!!?) and now all my pictures look terrible.

What camera can fix this? I'm buying it right away. Stupid D600.

The Leica Tri Elmar WATE
Really? You consider this the solution?




For me it is. My WATE works without any problems on my A7R as far as I can tell!

Mco, Hehe. At what effective resolution is a photo displayed on your monitor at that enlargement?

The answer is the Phase One IQ280, btw.

How does the Zeiss Distagon 21mm 2.8 work on the A7r? - seems the RF lenses are mainly impacted by the ray angles.

An image is built brick by brick by individual pixels. If you can't rely on the pixels being clean and transitions being reliable (as in the examples shown) the image as a whole will suffer.

Let's see what your stupid 600 produces - hint - use the best lens you have.

hmm, all my individuals seem have exactly one smooth color/luminance value. totally clean, not a single speckle of noise or any transitions at all within any of the pixels.

despite this, the quality of my pictures seems to depend completely on how i stack up the bricks (oops, i mean pixels) and not one what the individual pixels look like at all. when i upres the image to 11x, then add a bunch of noise to the individual pixels, and then down res back to original size the image looks exactly the same.

If I only look at one pixel, it looks perfect. I guess the problem is that 11:1 is so limiting. I really need to zoom in more.

That's a very depressing way to think about an image. I wonder what a photographer like Miroslav Tichý would have said about it? I mean, having made his cameras from what amounted to trash and producing some very evocative images.

You're using a garbage lens. This adds nothing to the conversation.

Where's your image ?

And again your not getting the larger point. It is about the transitions at the pixel level. Straight conversion, no sharpening, no smoothing.

The A7r fails at some transitions.

Yes - a mystifying contradiction.

I also decided not to pick fight with Harley gangs, yell "I've got a bomb" on an airplane, or throw a baby off of a high rise without trying it first. (and 1,000s of others)

How does one come to these less than sane conclusions ?

They read, you startling genius. They read as much as they can about the camera and begin to lean from "the greatest camera ever" to "maybe I don't need this set of problems".



No matter how this discussion turns out, I will enshrine this response in the FM hall of fame. Delightful

This become ridicules! You are not looking brick, but looking a piece of *** on the brick by zoom 1:11 or !:9.

When I visit great wall, I never pay a attention to brick but whole scenary. not to mention looks for **** on brick.

A7R have many limitations, but this green/red or white/green etc... can't make to the list.
