I haven't used the TS-E 45 myself, but I would guess that much of the chromatic aberrations can be cleaned up in post-processing, ie the lens works better in practice than seen on test charts.
Hi,
That's correct, for my copy of the TS-E 45mm anyway.
I also think that some of the comments about the relative performance of the 45mm versus its 24mm II and 90mm siblings is a bit overstated. Sure, the 24mm II and 90mm TS-E lenses are
very sharp, but the 45mm isn't all that bad IMHO.
Attached are 100% zoom crops from the TS-E 45mm f/2.8 on my EOS-1Ds Mark III, center, edge with full 11 mm horizontal shift, and the corner of that same 11 mm horizontal shift (so roughly at 45 degrees on the edge of the image circle). I used Capture One Pro 7.2.1 for the Raw conversion, with CA removal, no sharpening.
The first version remained totally unsharpened, and the second version had
the same Capture sharpening applied to all three crops in Photoshop. Output sharpening will make the images really pop.
In my opinion the results are quite good, with only marginally compromised extreme corner resolution. Maybe I have a good copy?
Cheers,
Bart
