There are techniques to work around dr, there are techniques to work around resolution also.

Just means more work, though sometimes you cant use any other options.

14-24 bad at 35mm? ouch high expectations.


I think he meant performance of 14-24 lens when mounted on 35 mm FF sensor.

That part about resolution is new to me. I've always thought resolution once lost cannot be recovered. Of course, if one always shoots static scenes, then stitching is an option.. but that is so limited.

Yes I meant stitching. And yes you cant use it all the time.

IMHO, Nikon's biggest handicap is their continued reliance on the mechanical linkage between the camera body and the aperture mechanism in the lens. I suspect this antediluvian contraption is the main reason they can't implement a workable Live View system, and no doubt it imposes other design limitations as well.



Doesnt the new 800 have an electronic aperture now?

Workarounds bear some risks and increase file size and working time

Yes they do. But we know the grass isnt pure green on the other side.

As Roger said, the camera we all want is bits from all the brands. We cant have it so pick your poison

no question about it is interferes with the mirror chambers size, but the choice was to continue support or not support older lenses

Nope...all Nikon lenses (except possibly the current PC-E lenses) require a mechanical linkage to open and close the aperture.

It is a pretty fantastic lens. The only real weakness is that around 40mm and up the farthest edges and the corners don't manage prime sharpness (and QC).

Just looking at some f/2.8 shots, lots of specular highlights, white, crisp black next to white and yet not even a hint of LoCA fringing, just clean, clean, clean and so crisp with the micro-contrast. The lens is pretty much a real APO design when it comes to LoCA. Not many lenses are. Not seeing purple and green all over, it almost looks like what is wrong with this shot!

The lack of LoCA is a subtle and yet not so subtle at all aspect of this lens that is often overlooked what with all of the focus on sharpness.

In the past only extremely expensive lenses/designs have been APO and well actually I guess the trend continues looking at the MSRP actually.
