NEX-7 + Summicron


Washington

I am tempted with the Nex-7 as a Visoflex replacement using my ME 90mm. I would also like to use my 28mm f/2.8 asph on longer backpacking trips without my M9 as a 40mm replacement. I found a single pic on the web using this lens with a Nex-7 and it was not so good in the periphery. Can anyone confirm that?

The 28mm Elmarit works apparently better with the Nex-5n but that camera does not allow to use both the EVF and a flash at the same time - not so good for macro.

I guess I should wait till May 12.

How long will it take between the Leica 10 May announcement and the begin of the sales?

 

Anyone has an idea?

I understand about the Summicron 28mm. But the Elmarit design seems to differ enough to potentially cause problems with edge resolution and color shift. Both 28mm lenses are retrofocus designs but not to the same extend.

Here you go with OOC JPGs, only reduced in size, no other processing.

Then Sony NEX-7 + 28mm f2.8 Elmarit-M ASPH @ f=2.8

 

To me both show a red cast in this situation that needs correcting.

 

I also shot some type of wall with the above combinations. No detectable color cast to my eyes.

Wide open the center of the images is sharp, edges however are soft.

Stopping down to f=8, edges seem sharp as well.

many thanks for that. strange. So it really does seem that anything less than is 35 is problematic with a cast and soft edges. It is strange then that both luminous landscape an Jono Slack get such good performance out of the WATE

The WATE is a different desing (and als a lot bigger) than the 29mm primes.

28mm SLR lenses neither cause colour shifts in the corners.

 

It is not only about the focal length, it is also about lens design.

And what is more in many cases you won't realize the shifted colours at all.

Thanks for that. As I said I am really looking for something to use with the longer lenses. I tried out the NEX 7 in store with my 90 Elmarit-M and was impressed with the handling and focus peaking but it is a lot to spend for just that use. I tried the Rich with the A12 unit and liked it but really wanted a bit more resolution and with the viewer etc it comes to the same price. May have to consider the NEX5n which is cheaper or wait until May 10 and see what leica comes up with which no doubt will be horribly expensive!! I did also try the xpro-1 which is fantastic with the fujinon lenses but not really much use with the leicas

To compare new and old oranges, both Summicron and Elmarit asph 28 need vignetting correction on the first APS mirrorless ever, the Epson R-D1 from 2004. But i haven't got the least color shift problems with them on the latter. I wasn't even aware that such a problem could exist then. I seem to recall that Epson used some offset microlenses on its Sony sensor but i have not kept any evidence of that (4 MB files).

Hi David,

 

The WATE seems to be okay on the NEX-7 + WATE @ 16mm, f=4, 1/1250 s, ISO=100.

However, the 21mm f/2.8 Elmarit-M ASPH seems to have a red edge on the NEX-7 @ f=2.8, 1/2500 s, ISO=100.

 

Of course, CornerFix should be able to correct these color casts.

 

In my experience the NEX-5N seems to be a better performer with Leica wide angle lenses.

If you would like, I could also do similar tests with my NEX-5N.

Hi David,

 

Yup, it certainly is, produces excellent images though.

It's wider than the WATE and even useful on the M9.

Another advantage of that lens, CS6 has the lens profile for the Nikkor 14-24/2.8.

CS6 doesn't seem to have the profile for the WATE.

Don't take this personally, but I am always a bit skeptical of posts concerning NEX/Leica/Zeiss wide angle corner and center sharpness issues. Especially when pictures are posted and they're followed by a line about "I shot something else with the exactly the same settings but I saw no effects."

 

Stop shooting JPGs, they're bad for you.

Thanks. You may be jumping to conclusions.

The last two images were derived from RAW images.

The first two were JPGs to show the red edge.

But I have them in RAW too, showing the same effect.

So, I think the JPGs were better suited to make a rather limited point.

That's all.

 

I typically shoot RAW only but reject your rather categorical statement

and will add JPGs whenever I feel like it.

Interesting thanks. Never tried the WATE with my crop RFs so far. I would not buy one to use it on a Sony but it's just me. I've decided not to buy any mirrorless camera before May 10th anyway.

 

Me too... :)... if Nex7 (from this thread's posts) is really so good, imagine what if Leica would announce an EVIL so made :

- Sony Nex7 sensor (why not ? They have to source one, at the end...)

- M mount "native" with lens recognition (so for the WAs...)

- X1 style/size ... but with addon height (X1 resembles a Leica I, this one would resemble a Leica II... ;)) to accomodate EVF

- Something LESS than Nex7 in gizmos like video, "special modes" which make only jpg (like the - interesting, btw - motion blur mode showed here)

 

Could be fine, I think.

The mirrorless Leica will be made to fit M lenses at least. Would be OK for me if it looks like that, even if it must be a PanaLeica camera.

Again, don't take this personally, the "JPGs are bad for you" comment was humor, something rarely seen and almost always misunderstood in here.

 

My experience shooting with a modern $24.99 4GB SDHC memory card, on a Sony NEX (or any digital camera for that matter) there is really no benefit to in camera JPG, ever. The higher quality of information that I can get on the card, the better. With my 14 mp NEX-5, I get over 250 ARW pictures per card. Shooting that way, I switch camera batteries before I fill a 4GB card. If you're rocking an 8 or 16 GB card with an NEX 7...that's alot of photos to manually focus.

 

The original NEX 5 sports a different sensor than the NEX 7 (or even the NEX 5n) but I have not had red edge color problems or "wide open" edge softness issues using either a Zeiss 25 or Elmarit 28. I am not using in camera JPG, only shooting in the ARW format.

 

I'm not questioning that your images didn't have an issue, but ARW may help deal with that wide angle "issue" in some situations. Or maybe not. Your milage may vary.
