Now was this critter inside or outside? Excellent with the shadow and highlights.

Re: Fun with the NEX cameras....

Jim, While I appreciate your kind words (Thanks! :) ), I must point out that I am not happy with the image.

I adjusted the noise levels manually. The auto noise reduction while it gave a "clean" frame was completely devoid of details.

Even here, the details are lacking. This is entirely because of the NEX sensor and not from the lens.

I will have to check this out further.....

Nice shot, Vivek. Interesting about the NEX sensor. Nearly everywhere I read tends to show that the NEX-5 has the most detail from an APS-C Sony yet, and there is even occasional moire, which could mean a very weak AA filter, no? Which raw converter did you use?

Douglas, Thanks. :)

That (weak AA and moire mush) is a possibility. The lens was not stopped down much (~f/4-5.6). I still can not rule out shake despite the apparent high shutter speed. That is why I am not sure of the source for the lack of details at the moment.


The high ISO sensitivity of the NEX sensor is really impressive.:thumbup:

Well, Douglas, that sure was in interesting read. :rolleyes:

Especially this quote: ...more evidence to me that if you want to maximize quality, use RAW...

Re: Fun with the NEX cameras....

I just ran across these two threads which you might find interesting.

I think that guy may have a point. As of now (after several snaps), I would be very hesitant to use the NEX sensor for macros with any of my lenses.

Even the Tominons are a bit too much for the NEX sensor.

I will just use it for what it is: take it everywhere tiny digital snap back. No more!

Really sad that there is no competition for the m4/3rds in the mirrorless cam arena.

Re: Fun with the NEX cameras....

Vivek, I am confused and failing to follow this thread. What is it that the camera sensor can't do? I don't have a macro lens but with the 40/2 I can capture extremely fine detail without moire at close range (up to lens distance limit).

Re: Fun with the NEX cameras....

John, "Extremely fine details"? I have a sample of that very same lens and I know how it behaves (I do not have a Leica M adapter for the NEX sensor)

I tried a few lenses with known resolutions (the Zeiss Luminars, for example resolve >200 lp/mm) they give strange results. The same lenses provide outstanding details when using a Panasonic G1 or even the Sony sensored Nikon D300. Also check out the SOM-Berthiot 25/0.95 example I posted earlier in this thread.

Heck, even the hacked G1 with no AA/UV/IR filter stack does not produce such mush. So, it is possible to take care of aliasing even in the absence of an anti-aliasing filter.

I hope Sony would issue a firmware update to fix the nuisance.
