This spectacular optic just got even sexier with the Hawk's M-mount conversion. First, a bit about the optic, this is the smallest and lightest with the least amount of distortion (only 0.5% distortion) 21mm f/2.8 out there. The legendary Distagon 21 has 4 more times the amount of distortion while being 3 times heavier and bigger. Having shot with the original Contax 21, the new Zeiss 21 and this Biogon 21, I would say this one has the best rendering out of the three (color, tonality). And that's why I still have it here after selling the other two. So why should you get this lens instead of the ZM? Well, first, this one looks cooler while being smaller and lighter. It has less distortion as well. I believe they should have similar performance. From my test, at f/11, this lens is absolutely perfect without softness or mid-zone dip. It's sharp to the very mm of the corners.

About this mod: Hawk's Factory has the best helicoid M-mount out there. The distance scale is spot on and meticulously laser-engraved for long lasting function. Hawk's helicoid work is among the best you can ask for, especially for this kind of mod. Best of all, even though the original Contax G focusing direction is turning the "wrong" way, this mod actually made it the right way, just like a native M-mount lens. The lens was also coded (as Leica 21/2.8 ASPH) and rangefinder coupled. Tested at Tamarkin to show no vignette on Leica camera. More importantly, this modification is reversible!

I hate to part with this lens, but I need the fund for other priorities in life. This comes with the original paper box, leather box, documents and the original filter (as well as a Hoya Pro1 UV filter). It also comes with with the two original caps and old Contax mount and parts to reverse the process if you like. It also has a matching custom-made rear cap in silver color for the new M-mount. Finally, the Hawk's Factory box is also included. FYI, the current wait time for this Contax G to M is 1.5 years.

I am asking $1230 shipped and Paypal'd within CONUS. I ship abroad as well, but additional shipping cost and fee should be factored in.

The Biogon T* 2.8/21 is one of the finest lenses I've ever used... to be able to focus manually (and very quietly at that) would be a dream.

GLWS!

Lytton, thank you. It's indeed one of the finest lenses. I hate to part with it. Here is a couple of shots taken on the A7s.

I believe this G 21 would be a fine addition to any M9 or MM shooter. You guys just need a little nudge to go through with this . I am waiting. I'm not in a hurry actually since I also enjoy this fine lens.

Hi Bill,

This is a helicoid mod so the lens now can focus just like any manual lens out there. I believe the other guy on eBay, who is also doing this kind of conversion, is using gear-driven mechanism. The reason is that Contax G lens focus direction is actually in the 'wrong' way (similar like Nikon and Pentax). This mod, because of the custom helicoid, alter that direction into the right way. Hawk's helicoid work is among the best from Asia I have tried so far. Also, as stated above, this lens was tested at Tamarkin showing to have an accurate distance scale as well.

Hope that cleared things up,

Hiep

Compared this lens to the current ZM, most G owners would point out that this lens is better in term of sharpness (I guess stopping down). The obvious points are that this lens is smaller, lighter and it has much less distortion.

Adding more pictures (none of these posted picture were cropped)

This lens has minimal amount of coma compared to the venerable Distagon 21. Another strong point for folks with wide-field astro interest.
