Thanks Peng, Smeggy. It is out by 0.51 on horizontal axis. I took it by kneeling down and lowering the camera to hip level so its a possibility that it is out on another axis. If the weather is ok, I'll redo

How about a ruler?

Hmm A900 and a set of ZA glass
Bad thoughts Robbie, Bad thoughts Robbie

Hehehehe big spat about nothing really
All of the shots on view here don't do much justice to what each lens is actually truly capable of, that moment of genius and wonder where everything clicks into place and you look at the image and just go wow!

Yep the A50 f/1.2 can produce creamy oof renderings without halos, coma, fringing but it is no way a standard aperture to be used, however it does have the capability if needed and your artistic needs warrant its use.

The FA43 can bite as well if not careful, its oof stopped down beyond f/4 can be nervous or harsh depending on the scene and at other times it can be a bit too sharp for its own good at f/2.8 if you're taking a head and shoulders shot for example. Poor lenses can't win. So I'll repeat what I said earlier but put it into terms that are instantly understood.

Ease of Use: FA43 - 9/10, A50 - 5/10

But...

I got this shot with the A50 f/1.2 @ f/1.6 (just a bit faster than the 43 could do)



And this crazy image that I love arrived via the FA43



Only way to resolve the original question really is to get one of each

Lens received safe and sound. Many Thanks David for a smooth transaction.

Beginning to fall heavily for this makro.

ISO250, 1/250s, f/2.0, -1/3EV

Neither is the 43 according to Photozone or Lenstip (not well liked that is)
Distagon 21 is not available in ZK, widest is the Distagon 25 which is a focal length I like.

I've promised myself just one more this year... the Distagon 25
Actually the A50 is looking suspect now. The Makro-P gets closer and its OOF rendering is kinda awesome. Never mind that it is sharper across the frame, smoother focusing and just well a more rounded, more versatile lens for me at least. 2/3rds of a stop? can live without it. Only thing i'm worried about the Zeiss is that perhaps it might be a teeny bit too sharp for faces

Started with these:




Now the cull is complete.
Down to these select few




Have I been too rash? Interested in your observations.
