p.3 #13 · So, which of the Zeiss for Canon lenses are great? | |
I have yet to see an unusable image from the not-so-many I have shot with the CY Distagon 28/2.8, and some have been revelatory. Loads of 3D, giant central resolution (see the MTF chart), and excellent corners given f8 aperture. This seems to be another of the 'gentle DOF loss' CY lenses, so not much need for f11. Mine is good from 5m to infinity, and works very well for intimate landscape shots, say 5-15 metres FD.
Just took a look at the MTF chart of the ZF28/2, wow, I am wondering why Zeiss/Cosina need their lenses to be so heavy! 530 grams for a simple 28mm is 200 grams too much!
If anything the CY lens is perhaps better but given different max aperture and stopped down aperture reporting (f4 vs f5.6) it is not too conclusive. I would expect poor corners (all sagittal lines really fall off the cliff) and maybe CA in the newer lens at the reported apertures. A big curvature hump also near the frame edge. But that is just MTF.
A great lens for APS-C is the CY, a light, small and supersharp 42mm eq. The ZF wil outweight many cameras (!) but you do get a stop more VF brightness, not insignificant in tunnel vision VF land.
