Crop-sensor lenses on full frame bodies

[Tannin]

How about not wanting to buy from a company which has a shocking record for supplying spare parts and service information (just talk to a VCR/DVD service techie) and an even worse history of treating customers with contempt and loathing, to the extent of deliberately infecting their computers with dangerous malware? Sony still has not even apologised for that particular stunt. Not to mention not wanting to buy from a company that goes out of its way to lock you into its products so that it can gouge you with exorbitant prices for must-have accessories. Who do you think invented the idea of putting a chip in a perfectly ordinary battery so that you couldn't buy any other brand for your video camera except (triple the going price) Sony-branded batteries? Who do you think insisted on equipping all its still cameras with proprietary, three-times-the-going-price, pay-a-royalty-to-Sony Memory Sticks instead of industry standard Compact Flash or SD?

With a track record like that, it would need to be a bloody good reason.

There is a few good reasons in the media at the moment too! It will be interesting to see how they recover from all this negative publicity.

Sony .......................
So it's more an issue with thier operation and corporate structure rather than the quality / functionality of the equipment ???
Only asked originally because I "inherited" Sony after years of being a Minolta owner.

I thought everyone knew of Sony's recent/current disasters. First their Playstation network was hacked, then again, and now their movie division. They are in damage control at the moment...

Sample of the Tokina 35mm macro on Canon 1D III. Uncropped, JPG straight from the camera.

Notice the tiny bit of vignetting in the top corners. With even the slightest bit of detail, you don't see it - observe the bottom corners.

For what it's worth, I experimented with the Tokina 12-24 DX on an F4 (my only full frame camera). The image was nearly circular at 12mm. You got usable images, albeit with some vignetting from about 16mm. All vignetting gone by about 18mm.

This varies from lens to lens, but in the case of Nikon cameras I don't believe there is ever a problem mounting a DX lens on an FX body. The quality of images you get from the combination may be a different story.

Go the other way and buy lenses intended for FX then mount them on a DX body, and they might even perform better. Though that's probably the worst possible way to get a wideangle lens on a crop body.
