Not really a fair test. The crop you show will have nearly 16 times as many pixels in the 500mm format as it does in the 135mm format. For distant objects there is no real substitute for longer focal length. If you were to compare pictures which occupies for the sake of argument, half the width of the sensor taken with the two lenses (you would have to be much closer with the 50-135), I think you will find that the 50-135 will knock the other lens into a cocked hat.
I've come to the conclusion that most of the people who get mirror lenses, or the 'cheaper' f1.2 lenses and complain about blurriness are one and the same: beginners who think a lens makes the photographer. They're both very sharp lenses when used properly. And by properly on the f1.2 that means using focus trap or a split prism, and on the mirror it means bracing against something and using high ISO's to get shutter speeds of 1/500th or greater.
Either way, I LOVE my DA*, and would only consider trading for a DA* 60-250mm at this point

This lens is what photography is all about! Little to no PP done on these either. Just LR3 beta 1 to convert.

Hell, it could be me, though I hope not because I've got too many other lenses already.

I have this lens, and it really doesn't get enough respect. For what it is, and the price you pay, it's really quite good. Most people will try to zoom into 200mm and then take pictures hand held of birds in poor lighting and then be annoyed when they don't look sharp. Smile and nod

The one thing that surprised me is that the TC doesn't seem to give you more than what software can get you. Has anyone else had this experience with 2x TC's? It's also possible that there was motion, and this motion was made worse with the TC. Both shots were pseudo-braced (camera on the ledge, but some shake was visible in the viewfinder).

Sigma have an 85mm f1.4 coming out sometime this year - aside from the HSM autofocus, their previous modern reimagining of a classic fast lens (the 50mm f1.4 HSM) is very well regarded indeed. Still, it depends on whether you can wait long enough for the (as-yet unannounced) release date.
I do wonder what's up with the price tag - I guess if someone does put down £10k for this lens then they will go out and make it by hand or something.
