Hello everyone.
My name is Alan and I live in Lincolnshire UK.
I have a Canon 450D and in addition to my autofocus lenses. I have a number of FD lenses, which I occasionally use with an EOS-FD adapter. However, despite the fact the adapter does have glass, it still will not focus to infinity satisfactorily and is only any good for use with my 100mm FD macro lens.
! would now like to try some of the M42 prime lenses and was wondering which adapter would be best for infinity focus with, for example a 50mm f2.8 lens, (not yet purchased).
There are quite a lot of adapters available on internet auction sites, both chipped and unchipped. Any advice from you guys, or links to information would be very much appreciated.
Alan. |

With FD to EOS adapter, lens cannot focus to infinity because adapter holds lens too far away from sensor. Some FD-EOS adapters have lens elements that permit infinity focus but degrade image quality much the same as a teleconverter degrades IQ.
With M42-EOS adapters, lenses can focus infinity no problem because the adapter holds the lens the correct distance from the sensor. AFAIK all M42-EOS adapters permit infinity focus.
Some M42 adapters have a flange that depresses the lens diaphragm pin -- these are useful for adapting M42 lenses without an A/M (auto/manual diaphragm) switch, to permit diaphragm operation, otherwise lens aperture is wide open always.
