p.1 #1 · Useless Exercise, Part Deux


Let the flames begin!

Another test, with the attendant caveats that usually accompany my not-so-careful tests: I was a bit rushed for todayís session, and didnít want to take too much of this kidís time, so I only have one comparison. I shot similar frames with the Zeiss 100/2 ZF.2, the Nikkor 105/2.5, and the Nikkor 70-200 VR (v.1). I tried to match focal lengths and framing as close as possible, but the guy moved in between, so there are minor differences. So I overlayed the files and cropped in a little bit tighter, to roughly equalize the framing. The high-res files are therefore only 3200 pixels. These were all shot at f/4. The huge caveat here is that I had enough DOF at f/4 to get the eyes in good focus even if my precise focal plane had a bit of variance, which Iím sure it did. Best I could do.

I kept the processing simpler this time, no skin retouching beyond zapping a couple of minor blemishes. I applied a bit of (exactly the same amount) of sharpening and Clarity in LR3 before exporting to PS. I did the same final sharpening to each large file in PS, then converted to 8-bit and sRGB before saving. I downsized to 800 pixels, and those small files got a round of mild web sharpening that the big files didnít get.

Hell, I dunno. I'll guess 105/2.5, 100/2, then the zoom, in that order. Maybe reverse the first two. Or not. Or mix up all three.

;- )

They're all good.

That's why we have kids - right? Test subjects. I vote for A=Zeiss, B=70-200mm, C=105mm. Great results you got with all those lenses regardless!

He's messing with us. These are all from the new 55-300mmDX.

I don't know Todd, but lens A is clearly sharper and with nicer colors IMHO

+1
That would be my guess too!

Yes, and I prefer the boke over B an C. Whatever the lens

This is tough because the first one has more focus towards the nose, the next two further back... so A appears to be sharper overall.

I'll go with (A) Zeiss, (B) 105, (C) 70-200, although I may have the zoom and the 105 mixed up.

That's very true, unfortunately, which is a huge problem with this test. I was hoping it wouldn't be totally useless, because we could still look at the 800-pixel versions and judge the overall character of the images, but that may not be true. This the hardest part of such a test....all I can do is focus as carefully as possible either by my eye or by the green dot confirmation. In this case I took several shots each with the Zeiss and the Nikkor 105, and chose the "best" (sharpest at the eyes) frame of each to my eye. I messed up on the aperture with the 70-200 at first and consequently only had one frame with that lens at f/4. It was sharp, though.

Lens A look quite a bit sharper with more details to my eyes.

Agree with vchowtoomanyletters. I shoot the zoom a lot and when I glanced at A it just looked familiar.

Of course we're probobly wrong. These tests have been an interesting revalation. Thanks.

I'll let this go for a bit. It's already pretty clear though, that there won't be consensus.

I am planning ONE more test, but probably won't have time this week. But I want to shoot someone with the specific intention of testing these lenses, rather than hijacking a regular session. I'll do inside and outside, 2.8, 4, and 5.6 or so.

I like B the best. The color and contrast are quite nice. I like the exposure of A the best. But I dislike the bokeh of lens A. C has the worst exposure, color and contrast.
