I can hardly find one.

Most posts here are complaints about the front-focus issue or the misunderstanding of it. Most pictures on Flickr show the awesome bokeh feature. However, I have yet to see a picture taken at a smaller aperture demonstrating edge-to-edge sharpness. Even if it's not the purpose of the lens, I would still like to see whether it is at least possible and whether the lens is also usable at a smaller aperture.

All reviews out there are written before people understood the front-focusing problem, and therefore are mostly bad. I haven't seen a good review on this lens. Unless someone can point me to one.

Nevertheless, I already placed an order for the lens. I really love the OOF feature of this lens as demonstrated by some shots on Flickr. But I still want to see whether this lens is also capable of taking a regular sharp image.

Wow. Is your lens optimized for 2.8 or 1.5?

This makes no difference for a lens stopped down to f/11 and focused at infinity.
 
Dr,

With the exception of a brickwall, what subjects will have everything in focus edge to edge at smaller(wider) apertures? Subjects at a distance really don't count as the DOF is wide (BTW, lovely Sonnar photos on your FLICKR stream mazhewitt). Also how do you make certain that the film plane is exactly parallel to the subject?

The Sonnar is not drop-dead sharp below f 4.0. If sharpness below f 4 is the most important lens property for you, don't get the Sonnar.

As others have stated: the Sonnar has a unique signature below 4.0. Above 4.0, it becomes a different lens. Most fast 50mm lens change between 1.5 and 4.0, but I think the Sonnar's signature changes more than most.

The Sonnar seems to be a truly wonderful lens.
I've got a Summicron rigid, I thought it was a lens I needed but I'm not very happy with it. The optical quality of the Sonnar is amazing and I wonder whether it's not the lens I'm looking for: sharp stopped down, creamy wide open. I've got a Summitar that IMO behaves like the Sonnar, but it's an old lens, and I would like a modern lens that does the same with a modern look.
Is the Sonnar well built?
 
Great pictures, Collum & Doug! :cool:

Some of them seem more like paintings than photos. Very nice picture taking by you guys!! :)

Collum, I really like your images. Is that from M8 or Film? Which film is that btw?

M8... coverted to bw with Alien Skin Exposure. this adds a bit of film grain to the image... i pretty much add that to all images.. never liked the 'perfect' look. Reality always seems to have a surface layer of 'noise' going on (either that, or i've needed glasses for a long time.. ). Although film doesn't really capture that 'noise' as well.. theh grain implies it

And I was thinking, what a bad combination of film and developer :D

I guess that really was my fault, i just noticed now that this was in the Ikon forum. (although i'm pretty sure there is a setting for oxidized PMK in there somewhere). This is one of the best 50mm lens i've tried...
