DSLR for Canon FD Lenses?
« Reply #20 on: September 29, 2005, 06:37:36 pm »

[Just a caution, the E300 focussing screen is next to impossible to actually manual focus with.  This is just from playing with it in the store, but I could hardly tell when I was in focus. ]

Well, certainly worth looking into, but again, with a 2.8 300, it might not be as difficult as a more normal lens over the counter.  Dan

If you are looking to make a converter for FD to 4/3 take one rear 4/3 mount from a Sigma 18-50 (available as a spare???)and fix the front mount from a FD teleconverter? Not tried it myself, but perhaps....

In UK SRB make converters to order.

 Thank you, sir, I will contact them either tomorrow or Monday and report.  Perhaps they have an answer. I know the chances are slim, but the possibility is too interesting to pass up.  Dan

Not surprising if you were using the E-300 kit lens, and so at about f/4 to f/5.6: you are working with the same amount of light and the same weak OOF effects as about f/8 to f/11 in 35mm format. The situation should improve greatly with brighter lenses; at least, I have no problems with the E-1 and f/2.8-3.5 lenses.

By the way, having more DOF in the VF due to the smaller format makes focusing less precise, but if the final image has more DOF for the same reasons, it should roughly balance out as far as visible OOF effects.

My rule of thumb is that for good focus sharpness as seen on prints, the main factor is having the wide open aperture used when focusing exceed the aperture used to take the photo by as much as possible. That is, have a lens of wide open aperture faster than you will typically use to take (manually focussed) photos.
