| p.1 #17 · 28mm 1.8G's optical problems something to worry about |
@mshi, I think I am staying away from the 1.4G primes for now, due to their price, size, and weight (they weigh as much as some of my zooms!). Whereas I can fit a D700 + 50G,28G,85G in a small bag.
For everyone else, I guess these are the kind of optical oddities I was talking about:
But it seems that you will get everything in plane with your focus point in focus, you just might get some extra too, which is okay with me. And, well, some slight examination of focusing may be a good idea.
Anyway, just being a worry wart, don't mind me.
Tim's review (linked above) is exceedingly thorough and excellent. But one thing makes me wonder about the copy he tested: when talking about some of the focus oddities he states "And if you turn it on its side, something rather marvellous happens." and some of those oddities disappear. It's been my experience in general (not on the 28 f/1.8 specifically, though) that a lens that behaves differently in landscape and portrait mode usually has a loose element inside that's shifting slightly with the change in orientation. It's possible his copy had an issue.
