DIY Lens mount conversion, results (see below for "how to")
Here is the completed Minolta 58mm f/1.2 modification mounted on my Sony Alpha DSLR. Originally the lens is for the Minolta MC mount, which can not adapted to the Minolta AF mount "passively", i.e. any adapter would need to have optical elements to maintain infinity focus (at the expense of image quality). I managed to replace the mount on the lens itself by substituting an M42 to Minolta AF adapter for the original mount. After readjusting focus on the lens, it now aligns perfectly with the original distance scale, all the way to infinity.
While I did this for the Sony/Minolta AF system, the guide to the modification (see below) applies to any current DSLR system for which you can get a suitable adapter, e.g. an M42 to Canon EOS or a glassless M42 Nikon adapter can be used.
The lens was chosen because there is no f/1.2 lens available for the Minolta AF mount and most other f/1.2 lenses available tend to be either extremely expensive, hard to find, and/or far inferior (e.g., the Tomioka 50mm f/1.2 for M42 is not very good in my opinion). This lens, on the other hand, cost me about €100 and has bokeh worthy of legends. It is not the sharpest of lenses wide open (still, quite decent), but it has very pleasant image characteristics and is a lot of fun to use.
I recently updated this modification by installing a microchip which identifies itself as a 60mm f/1.1 lens (closest setting available at the moment). The chip was kindly provided by James Lao, who makes custom chips and M42 to Minolta AF adapters. If you use an electric adapter for the mount, the exact same guide can be used, or you can later install the microchip on the adapter (as I did).
With electronics the focus confirmation and in-camera anti-shake both work with this beast. (Focus confirmation doesn't depend on reported focal length, and for anti-shake the slight difference doesn't really matter that much.) The in-camera anti-shake of Sony DSLRs makes this a low-light photography marvel.
See the pictures beginning from here for my complete writeup on doing the modification. This method can also be applied to some other lenses, and certainly for converting to camera mounts other than Minolta AF.

At the September 1980 Photokina, Ilford introduced the world's first chromogenic black and white film, Ilford XP1. It provided users with the opportunity to obtain black and white images from a film that takes advantage of the convenience and widespread availability of C-41 processing.

When it gets a bit too warm outside for all that other stuff I've been mentioning (and trust me, around these parts, those overly warm days are coming soon!), stay inside and watch a movie or two. This particular Fred's seemed to have just a bit more of these electronic/entertainment items than many of the others I visited, which makes sense given the amount of vacation homes in this area.

This Tokina 16-28mm has been my superwide zoom lens of choice for my Canon 5D3 for a couple of years now. It is razor sharp and has produced some of my most popular images on my Flickr stream.
A few months back autofocus just stopped working ... I have no idea why. The lens has always been treated so well, never dropped, never exposed to bad weather, always spoken to nicely ...
Anyway, I took it into a camera shop and decided not to go down the path of getting it sent off for repair. I took this photo for my ebay listing, but thought i'd put it on my Flickr stream as a tribute! I've replaced this lens with a Canon 16-35mm f4 which is a real gem (and even sharper!).
Farewell faithful little Tokina!

I picked up my 3rd 5D2 after flip flopping between full frame and 1.6 crop. I decided I needed both.
It went like this 40D to 5D2 ( thought all my lenses were too zoomed back), back to a 40D (then went OMG 5D2 quality is 10 times better), back to 5D2(was happy until the 7D came out),to the 7D. Then for the last year I said I need both and finally picked up the 5D2 on the B&H sale. I'll have my 7D for sports and macro and the 5D2 for full framey shots. I got some stuff lined up so it should be paid off in no time.
