Aperture mode on 4/3 with M adapter?

[totifoto]

Maybe this has been asked before here but me and this search engine here dont work well together 🙄

I´m thinking of getting the EP1 or the rumored EP2 with the 20mm panasonic. But I also wanna get the M adapter for my M lenses (onlu have 2 though)
I always shoot aperture mode. How does that work when I have an M lens on a Micro 4/3 camera? do I have to have the lens wie open and control the aperture on the camera or can I use the aperturering on the lens?

Thanx

On the G1 you set the selector dial on the camera to "A" (aperture priority) mode, then as you adjust the aperture dial on the lens the camera selects the correct shutter speed for the metering and the chosen ISO. The EVF/LCD gains up or down as you adjust aperture on the lens to give you a consistently bright viewfinder scene. So you're seeing DOF effects real-time, prior to releasing the shutter.

You also have to select "shoot w/out lens" in the menu to let the camera know that you're using a non-electronically coupled lens.

The camera doesn't "know" what aperture you're using; rather, it judges how much exposure time to give based on how much light comes through your manually adjusted aperture, based on the ISO setting you've chosen.

Use Google. If you enter "[search term(s)} site:rangefinderforum.com", you're far ahead.

You're welcome. 😀

On the EP-1, you don't have to select "shoot without lens", and you get in body image stabilization with manual lenses.

Worth mentioning that focussing is a little more involved when shooting with an M-mount lens. This is based on my experience with the GF1 and I'm not sure whether the EP1 handles things identically but..

If you have the 20mm 4/3rds mounted and are manual focussing, as soon as you start to focus the lens the image on the LCD zooms in tightly on the subject so that you can judge focus. Once focussed, lightly press the shutter and LCD switches back to full frame view. If you're using an M-mount lens the camera has no idea that you're attempting to focus the lens and so you have to button around to first select an area on the LCD and then it will zoom in. Slows things down a bit and certainly makes things less practical. That said, I have some good results from an old Jupiter 8 on the GF1.

But why would you need to zoom in for focusing? Can't you focus from the screen alone, or is the screen resolution too low for that?

Maybe with the EV-F it will be more better?

I'm asking because I'm really tempted to get one to use with my Leica and OM glass 🙂

Well you might be able to focus without the zoom but if you're looking for absolute accuracy then you'll need to zoom in to focus, especially outdoors where the light makes judging focus on the LCD quite difficult. Either way, it's not possible to pull fast accurate focus as you can with an RF.

If you're able to zone focus via the lens markings then that might be the way to go. Put an optical viewfinder on top and you're away. Otherwise you're probably better off using M4/3 lenses on this camera rather than legacy M mount even if half the fun of the M4/3 camera's is being able to mount practically every lens made!

The EVF screen is great for focusing without having the zoom function switched on. The image pops clearly into focus nine times out of ten and its one of the things thats so impressive about the EVF. Only for critical close ups or extreme tele shots do I use the zoom focus function.Steve

Interesting. A recent review (can't remember which) said to forget trying to focus with the GF1 EVF. I wonder if anyone else here has attempted to focus an M-mount lens through the EVF?
