In Topic: Am I going soft: Nikkor 16-35mm

30 September 2014 - 04:32 AM

I use the 16-35 with the Nauticam 230mm dome without a diopter.  The problem with diopters is that they narrow the angle of view, and the 16-35 never seems wide enough anyway. (I moved from the Tokina 10-17 on a D7000 to the D800) And diopters are seldom made with the care and expense of native lenses. (I use B&W ones if I have to use them at all.)  It always seems that my corners don't look as sharp as Alex Mustard's, but that may be because he knows where to focus to include the corners in the depth of focus, whereas it's all a blur to me and I use AF and hope for the best.

With the D800 I don't need the zoom range (you can crop a 35 out of a 16 file and still have an acceptable picture) but I tried Tobi Bernhard's 14mm 2.8 in Tonga last year and it didn't make me want to buy one; the corners were not great.

If you don't need high ISO particularly, I think the loss of the 10-17 is a high price to pay for 36MP files from the D800. Much as I like the ability to crop the shit out of them. And of course you can use a much smaller dome with the 10-17...

I made the switch from D7000 to D800 Nauticam. I convinced myself that the high ISO ability would be useful, cropping etc. But really the big drawbacks are the loss of the Tokina 10-17 (and the ability to use small domes) and the increase in size and weight. I do like the ability to crop drastically but the weight and size is an issue for me. The 16-35 is ok, but seldom wide enough, and I'm not fond of the fisheye look for many subjects with the Sigma 15. I think would stay with the D7000...

At the very least you need something like Lens Align to calibrate every lens to that particular body. The amount of AF fine tune you need will vary for each lens, with zooms you will need to choose a compromise as the amount of AF fine tune required varies with focal length usually. I think we only have one lens that requires no AF fine tune, but some require as much as -18.

There's no shortcut to doing this yourself and you can learn from Google how to do it.  We also use Focus Tune, but for most purposes I think Lens Align is enough.

Perhaps Nauticam will make a housing and adapter for this to work with a Nikonos 15mm lens - which would be a handy size even if the corners are no better.
