John -- Thanks so much for this comparison!

I agree the ZF/ZF.2 have impressive contrast and combat flare very well. Probably lens design and as you suggest newer lens coatings.

Of the two 28's, the D28 f/2.8 seems sharper in all areas, when compared to the "Hollywood" (which is also a newer, if intermediate, design). (Maybe I'm thinking of the poorly recieved ZE 28.0, not the older "Hollywood" Contax?)

I'll test that if and when the sun shines

Which ones of these I will keep might come down more to focal length spacing with my other lenses.

I have the Loxia 21 at 91 AOV, so the 25 (80) may be a little too close

right corner

I'm thinking the softness here may be due to focus plane/DOF where i've focussed on the center and the scene is not equal distant between the left and right corners

Hollywood seems to have a dip in midzone and improving into the corners

You can get the ZF 25 f/2.8 for about $500 these days, and it is a steal at that price, so the price difference is all that huge between it and the CY 28 f/2.8. Both are nice lenses, but I too prefer the ZF in these tests.



I got my ZF.2 25mm 2.8 for US$340 last year.

Nice test, thanks for doing it!

All seem similarly colorful in the corners (CA), otherwise I prefer the 25 2.8 ZF from this test.

Excellent comparison. Thanks John. To my eyes, all 3 lenses are very similar in the center, with the 28mm 2.8 being slightly better in the midzone and corners. This test certainly exonerates the 25mm 2.8 from the bad press it occasionally receives. It seems like a great lens to me.

This test does not show the large amount of field curvature the 25 2.8 has which is not everyone's cup of tea. The lens is at its best stopped down like this at 5.6 or f8 at infinity which is good for landscape shooting.

I compared the ZS 25/2.8 to several 24mm's a while back (on A7), http://www.fredmiranda.com/forum/topic/1342704/0

Whilst the ZS was best at infinity, it lagged behind in the foreground corners.
Because I usually shoot my landscapes with foreground lead-ins, and because of the weight, (the Z* feels very front heavy on the A7 IMO), I decided to go with the MD 24/2.8, with the the OM Z 24/2.8 as 2nd choice, (although the FD 24/2.8 was definitely the best for greatest dof at each aperture, but I disliked the ergonomics and colours.)

However, for close up performance, the Z* wins every time.
