Anyway here's a tip i would like to pass on for anyone who is mixing AF lenses with manual focus lenses on Canon SLRs, or anyone who wish to make their Canon slr / dslr behave like a R9 or M7...:p First, set AF point to one only (centre). Under custom functions (for the 20D it is in the menus), select Custom function 4-1. What does this achieve? primarily.... 1) Using centre AF point only assures faster focus rather than let the camera take its time to choose an AF point. You choose where you want to AF. Applies to AF lenses, of course. This kind of simulates needing to focus with the centre rangefinder patch on the Ms.......... 2) More importantly, you now (auto)focus with the * button instead of half pressing the shutter release. This means you do not have to keep on refocusing using AF lenses every time you half press the shutter release. You only focus once using the * button, then fire at will if subject distance does not change. This is similar to using a Leica M6 / M7 / R9 :) 3) Auto-exposure (AE) lock is now by half pressing and holding on to the shutter release. VERY much like a M7 :P Previously, AE (and AF) was achieved when you half press and hold the shutter release, and AE lock is by the * button. Now AF, AE lock have separate buttons. 4) Doesn't interfere with the use of R lenses, but now you can half press and hold the shutter button to achieve AE lock. again, quite similar i believe, to using the M7 in AE mode. The summary of it all is that your use of AF lenses will follow a similar pattern to how you use manual focus lenses. Basically focus (using * buttton for AF lenses) and shoot, without needing to change focus if subject distance doesn't change. Nikon has a similar customization as well, for those using Nikon SLRs.... In the original configuration, and indeed, how all AF cameras work, is that it auto focuses EVERY TIME you half press the shutter.......... hope this helps :) ---------- David Teo On 11-Feb-05, at AM 09:08, Ted Grant wrote: > Hi Tina, > Basically as you posted would've been my response to Phong also. > > I already have Leica lenses and as long as they work on the 20D I'm > going to use them.
