Saw a reference on that other site to this (AF Confirm / IS Programmable chip for Micro 4/3 EP2 GF1 - eBay (item 230519768021 end time Sep-11-10 21:38:00 PDT), so I went and ordered one:




Once it arrives, I'll attach it to one of my M mount to m4/3s adapters and see how it goes with my M mount lenses. From the report on the other site, it does appear to work, but needs some practice. The good thing about this seems to be that, if it does work, coupled with the VF-2, it should be a lot easier to get quick focus with manual lenses.

I guess it's a matter of nothing tried, nothing gained.

Cheers

Hmm, it does look interesting, I thought IS is normally enabled with legacy lens in-body with Olympus cameras?

It is and you set the focal length in the IS setting quick menu. I'm not quite sure what the chip is supposed to do with the IS activation.

Looks like all it does is feed the pre-set focal lenght data to the camera.

It would be interesting to know how effective the AF confirm is and how easy it is to program as it says programming is via the camera.

Ray,

I have got one for my Canon FD adapters for my E-P2. Programming the lens focal length and maximum aperture is a 30 seconds task once you get the hang of it.

My AF confirm is not consistent as for some of my FD lenses, I do get both solid green light and beep.

I would love to learn your experience. My supplier reminded me to program the front and back focus settings which I am lost as I don't understand what are these?

Thanks.

From what I read on the other site, getting consistent focus notification possibly boils down to getting used to how it works. I don't ever use the beep, so if it simply gives me a confirmation light, that's fine by me. As I'm also using the VF-2, I should be able to easily confirm that focus is OK when the light comes on. Once I get used to it, I may be able to rely on the chip without referring to the VF-2.

The front/back focus control I think is there for adjusting lenses that don't focus correctly. I'm not sure if this will apply here, but you never know, as some adapters can be slightly out of correct focus alignment.

Cheers

Ray

OK, I received the chip this morning and installed it as per the guide. The fitting was relatively easy and looks to be near perfect. Unfortunately the chip does absolutely nothing. I've emailed thesupplier and wait to see what sort of response I get.

One other thing about this chip is that you can't use lenses like the Voigtlander 28mm f2, as the rear lens element housing protrudes past the bayonet flange and won't fit past the chip, which partially blocks the mount opening. I don't know how the poster at the other place got his to work, but this one doesn't. I tried it with the EP-2 and a Minolta M mount 90mm f4 lens, couldn't be bothered trying any others as it shouldn't make any difference.

Live and learn I guess.

Cheers

Ray

I have gotten these AF-confirm chips to work on 4/3 cameras, they work ok, you half press and hold the shutter like you are trying to AF, then you turn the ring to MF and it beeps when the focus is right. the problem for me is that when using fast lenses, sometimes you just can't react fast enough when you hear the beep to stop turning (or maybe i just turned too fast), so the focus is still a bit off, so you still need to fine adjust it, kinda defeats the purpose so I ended up using MF mode most of the time even with the chip.
