p.1 #1 · Check Out My Amazingly Sharp Lens!


Man, I just gotta share the results from my Amazingly Sharp New Lens: check out these pictures: the first is shot wide open, and the second just half a stop down. Both were handheld at ISO 320. This is full frame . . .

This is just the top half(ish) of a 5D full frame:

It's a Pentacon 6 mount Carl Zeiss Jena Biometar 80mm f2.8 mounted on a Vivitar, Hasselblad-formulated Mamiya 645 mount 2x teleconverter adapted to a Mamiya-Canon shift adaptor mounted on a Canon 1.4x teleconverter with the pins taped. On a 5D.

With hardly any trouble at all, the same method transforms my $250 CZJ 300/4 into a handy 1,345mm / f11 for the 400D . . . ace!

It did, but it's OK because I removed the mirror and mounted it periscope-style in a toilet roll inner tube sellotaped to the hot-shoe. Now everything works great!

Seriously, though, you should have known that Canon's 1.4x TC, on which the lens is mounted, would never have mirror clearance trouble, as you can see in this annotated picture of my Amazingly Sharp 224mm f8 special edition. That's 358mm / f8 on a 30D.

Incidentally, if you'd like to see 100% crops of these images, you can't.

Hubsand,

I guess the long wait for the ZD back is taking its toll. The shots do look very sharp though.

My ZD back landed at Nottingham Airport at 2.44pm today. I've delayed a long series of location shoots in order to use it throughout the back end of the summer. Until it arrives, I'm giving some of my MF lenses a workout on the 5D.

Anything looks good resampled down that far – even the CA-powered catchlights in the cat's eyes . . . on my forum you'd be banned for posting a downsampled image and even mentioning resolving ability in the same post!

Now add a coke bottle in the middle to correct the blue CA back towards the red end and you're done!

Adapter Thickness will also comes to play with your adapted lens for this sensor.

What is it with you and adaptor thickness?! My Super 224mm f8 contains no less than two adaptors, AND two stacked teleconverters; it laughs at such trivia.

I guess if you put it lightly that way! But seriously the adapter thickness will show up in your medium format sensor.

Sheesh! Can't a guy have a little fun? That Frankenstein monster is actually pretty darn amusing & it's impressive that it not only works, but works well. Besides, it's not a MF sensor.

You can't tell zip from those images. You've lost me on this one.
