    <p>No, both of those pictures show lots of ghosting and starburst from the points of the iris. Steven is talking about smearing caused by spherical aberration (or overcompensation for spherical aberration).</p>

  2. <p>There are several comments about the size difference between the CV 40/2 and various Nikon 50s, but 40mm is notably wider than 50mm. If you want a small lens and a wider view, then it's more meaningful to compare it with 35mm options.</p>

    <p>In that case, the Sigma 35/1.4 may be quite nice, but it's also quite large. The Nikkor 35/2 manual focus lens is nice, but also a fair bit larger. The 35/2 AF Nikkor is smaller than the manual focus Nikkor, but not as nice a lens, and it's still bigger than the CV 40. The 35/2 Zeiss is a brilliant lens, but it's huge and quite heavy.</p>

    <p>All of which leaves a nice niche for the CV 40/2: the same size as the short version of the 50/1.8, with a wider view. Mihai mentioned busy bokeh, but to me it seems usually better behaved than the various Nikon 50/1.8 lenses. And like he said, this lens goes nicely with one of the small longer lenses, like 105/2.5 or 85/2.</p>

  3. When you do the "full manual" experiment, set the aperture with the aperture ring, instead of electronically. That should

    help you isolate whether aperture control issues are part of your problem.

     

    Also, you mentioned that the camera might meter differently near wide open because it sees vignetting. Since the camera

    always meters with the lens wide open, this should make no difference.

  4. <p>It's interesting, though, that the bad corners are really the corners. If you come in a couple of mm from the corner, it's much cleaner, even at f/2.8. Not as nice as the modern lenses, but it is quite small and easy to have with you.</p>
  5. What's the "MP" in Zeiss 100 MP? Is that the Cosina Zeiss lens, or an older one? The modern Zeiss seems marvelous,

    from what I've read and seen (without having used one), but it's twice the size and weight, and ten times the price, of the

    little old Nikkor.

     

     

    Is it fair to say that the 105/2.5 is one of the very best Nikkors that you can buy for under $200?

  6. <p>The normal Katzeye screen for the D700 has a small split image at its center. It is possible to order the screen without the split image, so that you have a uniform matte screen. This ends up looking just like the original D700 screen (and doesn't interfere with spot metering), but it's notably easier to discern focus on the matte area.</p>

    <p>Beyond that, with your manual focus lenses you should be able to treat a D700 like a (large) F3 or FE. It's certainly a camera that stays out of your way.</p>
