Here's a brief comparison of the 47XL vs. the new 43XL… for everyone, who is interested.
Sorry for the strange and boring images but that was in the front yard of Cambo and this is simply how it looks like in that quarter…
- both shots at f11 on P45 with 20mm lateral shift
- the 47XL with centerfilter, the 43XL without
- processed in C1; no furhter adjustments except of camera profile, WB, LCC, sharpening 200-0.8-0.8. Zero noise reduction.
Attached a screenshot of the 43XL's light falloff… which is exactly the same as the 47XL (~ 2 stops at 20mm lateral movements in horizontal compostion), a comparision of the scene (the sensor plane of the P45 in center position darked) and 100% crops from the far edge at 20mm lateral shift.
These are just my first impressions… so please take it with a grain of salt.
What I am seeing so far…
- the 43XL is a bit contrastier at the edges
- the 43XL is a bit sharper at the edges but not much
- the 47XL shows some CAs here, whereas the 43XL is pretty clean
the centerfilter on the 47XL might also play a role here, although I have never noticed a real image degradation due to the CF - not even in direct comparisons with and without CF.
The 47XL with CF shows much less noise at the edges than the 43XL without CF. So IMO there is in fact the need of an CF also on the 43XL for optimal results… otherwise you end up with at least ISO200 at the edges (if you shoot at ISO50).
Of course this is especially an issue on my P45…
No images here but the 43XL is noticeably better than the 47XL at f8.
At f5.6 it shows a similar falloff (and "glow") at the edges as the 47XL…
So… the 43XL is IMO a moderate improvement of an already very good lens.
If you miss a better performance at f8 with your 47XL, the 43XL is the better choice.
The slightly better contrast/sharpness of the 43XL at large movements is nice… matter of taste whether this justifies the higher price.
