Skopar 25mm vs. Biogon 25mm

[drjoke]

Is there any real-life or MTF comparison? Is this worth the price differential? Biogon does not come with a viewfinder, so this makes it even more expensive.

However I hear many good things about the Biogon. Searching for both lenses through Flickr appears to confirms what I hear that Biogon 25mm is really in a class of its own.

However I would like to hear from people who have first hand experience with both lenses.

The Skopar was no slouch, but the Biogon is really first class. Many of my recent street images in my RFF gallery were shot with it.

The old version of the 25/4 Skopar came with viewfinder included. The new 25/4 P does not. To mitigate the additional cost of an auxiliary finder is the fact that new version is in M-mount & therefore there is no additional cost for an LTM/M acapter as required by the old LTM version. The newer version has the additional benefits of a closer minimum focus distance (0.5 m) & of being rangefinder coupled - as is true for the Biogon in both regards.

The speed alone of the 25/2.8 Biogon is going to make it more expensive than the 25/4 even if there were no optical benefits, which there appear to be since the 25/2.8 is regarded as the best of the new Zeiss ZM lens line-up.
