i'm thinking of getting into nikon, these has been on my mind for a while now, probably a d300s. i started looking at what lenses i'll get when i go nikon, i got my eye on the 24mm f/1.4g, 50mm f/1.4g and the 85mm f/1.4g. according to the review here on photozone all these g lenses shifts focus stopped down, there's a chart on the review which shows this, would this be noticeable in real world shooting? is it that bad? i hear a lot of complaints from canon 50mm f/1.2L users regarding focus shift and how it ruins the entire photo.
anyone here experience focus shift with these nikons?
thank you

Just one comment as to focus shift with 50L: first of all, one of the people who was most vociferous and had the biggest problems with regard to focus shift on the 50L on POTN, switched to Nikon because of the problems he had with 50L and 1D Mk IV. That lasted a little over a year, when he switched back to Canon, about half a year ago. He recently acquired a new 50L - zero focus shift.
Furthermore, focus shift is/was limited to a very specific range, namely about MFD to 1.8 m, only at apertures from F/1.4 to about F/2.8.
However, it looks like Canon has this problem entirely under control now, and anybody who shoots with a 50L for a while, and likes the 50 mm FL, wouldn't want to miss it.

' /> and I tested 5 different specimens over a period of a year and a half, when things were still quite bad. The specimen I still have, which sits as main lens on my 5D II, only had some constant back focus rather than focus shift and was calibrated to perfection by Canon, even if it took Canon a second go to get it perfect.
Other than that, most fast lenses (F/1.4 and faster) show focus shift, unless they have perfect superapochromatic correction. You need to get to know a lens well so you can deal with it, if you are after the rendering such a lens provides.
HTH, kind regards, Wim
