14mm on FX vs. 10.5 on DX view.

Hey,

here is something it may be of interest for some..

I tho the results were suppose to be different but the 10.5 on DX still much

wider than the 14mm on FX, I know that is a fish eye.. just my 2c.

 

PS, this is not to judge the camera or the lens quality.

A valid comparison of angle of view would be to use your tripod mounted D3 with both

lenses (using the DX option on the 10.5mm) and to use Capture NX's de-fish option on the

10.5mm image

How does it compare if you straighten out the fisheye?

both cameras were mounted in a tripod at 100% the same distance.

 

I don't have the software to defish the 10.5, but I'm sure someone here will.

Wow does the 14mm really keep lines that straight out of camera?

Ryan, yes see this I did with the 14-24mm at 14mm (Juan however maybe usign the

fixed focal length 14mm Nikkor) :

Wow! The colors and crispness of the 10.5 is much, much better than the 14.

Dan - I'm not sure that's a safe assumption without knowing more about how these were shot.

Just checked the EXIF. Both at ISO 1250, f2.8, strobe fired (can see the specular highlight

on the globe).

 

I'd say it's pretty clear, the 14mm fixed Nikkor is nothing to brag about.

If you have Capture NX (should have come with your D300), it will de-fish the 10.5mm/f2.8 DX. The quality is not that great, though. Center is ok but the edges are very poor.

It's not clear to me what we're supposed to gather from these photos. Something about exposure? Dynamic range? High ISO? Performance at maximum aperture? Seriously, we're looking at photos taken with two different cameras, two different lenses, apparently not from an identical angle or mount position. Is this to illustrate light falloff at the corners and edges of the FX camera with an ultra wide used at maximum aperture? Something else?

Dan, I wouldn't jump to that conclusion yet. The D3 was shot in manual with different metering. Also, the fisheye has the benefit of wider angle to pick up additional light from the window source as well as the walls.

 

Maybe the 14mm is a bit weaker holding light towards the edges, maybe it's even a bit softer. But also maybe neither of those is true. Not saying the fisheye isn't sharper, only that IMO this is not a good test to determine that.

hmmm Lex..

by any chance did you read the title..???

 

14mm on FX vs. 10.5mm on DX view.

 

just by the title you can tell if is of your interest or not.

 

BTW.

both cameras were mounted on a tripod at same distance.

Setting were the same in both cameras, but I didn't put mush effort to show the quality of the camera nor the lens, just the view from both lenses in different format.

Dan - In terms of color and sharpness, I was also thinking about any processing after-the-fact, either if they were in-camera jpegs or in raw processing.
