Love the images produced by this lens and it's my most expensive (alt) manual focus lens >_<. I reckon it's worth it though and the fact that it's a ZF-I makes it all the more special.

You bought a Zeiss 50/1.4 and a right-way-mirror?

Hehe, nice one.

Lens, camera and KatzEye focusing screen. Actually my first own "worth something" alt lens. And probably not last (infectious bug that Zeiss one).

Hehe, so now you will be out there, focusing on 3D-looking things 2-5m away with an interesting background, at f/1.4-f/2 Try a stitch as well.

Good guess, kinda what Im doing right now. Im doing stitches pretty much since I have digital camera, so I will just continue, so far it looks quite nice.

Im quite curious, what does ZF-I mean?

Side-note: I would kill for that lens..

It was made for industrial applications, hence the name 'ZF-I'. It features locking screws to set apertures and focus at fixed position so that people can use the lenses to make really precise measurements and comparisons.

Optically, it's essentially the same as the ZF/ZE/ZS/ZK lenses. However, it has a chrome finish on the body, most likely to differentiate it from the mainstream series.

The short article here might explain it better than I can

Here's an Auto Mamiya/Sekor 21mm f/4 SX lens that I just received, and a sample image from a 5DII, 1/800 sec, f/8, ISO 200. It's very sharp in the centre, less sharp at the edges.

The first photo shows the 21mm f/4 SX mounted on a 5DII, followed by an example full image, resized to 800 x 533. The next photo is an edge crop from a 2000px x 1333px version of the same image, to illustrate how the edge region looks on an image sized for display on a large, high resolution monitor. The third image is a 100% crop of this edge region. The entire image would proably be just fine for 8" x 12" prints, but the edges aren't so great when pixel peeping.

The 5DII mirror hangs on the shroud around the rear element for subject distances of from about 5m to infinity (about 1/3 of the focus ring range). The mirror releases fast & easy when you set the focus distance to about 5m.

The Mamiya/Sekor SX mount has an aperture ring overhang, or raised edge, of about 1.5mm that has to be ground off before you can get infinity focus on a standard M42 adapter, as shown in the last photo.

Going for broke, eh? There is no tomorrow, do it today!

Apparently "I" are silver.. Or at least this type is. They could do regular in silver too, would match some cams nicely.. (true, mostly film cams, still worth it).

^^ Was it a software update that bricked your camera? ^^

A Zeiss Jena Biotar 58mm f/2 in Exatka mount. I had to modify the mount a little bit in order for it to clear the mirror on my 6D. Only had to take off ~0.009".

Nex-6 and 16-50, and summilux 50. love the Nexilux combo! e-lens is just for snapshots and video. image shot with my phone

I've been concentrating on lenses made between 1840 and 1859. I shoot these on my Chamonix 4x5. My latest lens is an 1858 Derogy Petzval. It's about a 150mm and just barely covers 4x5. It's beautifully machined and finished!
