Ok, I'm confused by this camera. I assumed the metering would work the same as on my EOS DSLRs.

Instead, with a Pentacon 135mm attached using either a chipped or non-chipped adapter, adjusting the aperture control on the camera affects the shutter speed. Therefore I cannot use the cameras meter. Unless I set the cameras aperture to the same aperture as I intend shooting with the lens, but this will slow things down considerably.

Any EF-M owners have knowledge?

You will have to switch the camera to step-down metering. This is done by setting the aperture to 1.0 and leaving it there.
Now you can set the aperture at the lens and the shutter speed at the EF-M and it will show you if it thinks the settings are ok metering-wise.

Of course you have to make sure the aperture on the lens it set to "manual", too Smile ...

Thanks, so I can only shoot in manual an not aperture priority?

Why F1?

Because f1 enables step-down metering if no automatic lens is attached ... see it simply as a switch ...

Give it a try what happens when you set f1 and shutter on "A" and turn the aperture ring Smile

Is this the official way of doing it or just the way others have found it works?

It's quite a handy camera isn't it. Shame the flash sync is only 1/90 though.

It's the official way ... "non-electric" lens + f1 enables step-down metering

Now that you have had this camera for a while, what do you think of it? I have seen one at a good price and was thinking of buying it.

I love it!

Most of my M42 lenses work well with it except my 24mm Tak which causes the mirror to hang up until I unscrew the lens. My EF lenses are great to use with it. I even managed to find the dedicated flash for it.

I've just processed the 1st film so I'll post samples as soon as I get around to scanning.

They crop up quite often on the auction site for 10-20gbp.

Thanks Martin. I've just picked one up on ebay for £22.50 in near mint condition. I hope the screen is as bright and as easy to focus as I've heard as my eyesight isn't as good as it used to be!

That's a reasonable price. Yes, the viewfinder is big and bright and the focus aids are very good.

Do you have any EF lenses?

Reasonable? That's an absolute bargain!

Some seem to go for silly money. I bought one for 7gbp and another for 15gbp.

Cosmetically they were both good. The 1st one had a fault so it was returned.

Yes, I do. I have a 50mm, 17-40mm, 24-105mm & a 70-200mm.

I found myself using my EF lenses in favour of M42, simply because I can control them in-camera. I'd be interested to hear what lenses you prefer to use with it.

My sympathies regarding mirror hang with 24mm Tak on film/FF EOS cameras. Tragic imho, such a great lens, no question results would be phenomenal.

The average price on German EBay for this cam in good condition is somewhat about €60-70,-!

It still takes the pic, but the mirror stays up until the lens is unscrewed.

Carsten - That's still not a bad price for a good camera. It seems reasonable build. I'd still sooner have a Spotmatic for M42 lenses though and they're slightly cheaper.

I tracked down a Canon GR-70 grip extension for the EF-M. It makes a huge difference to the handling of the camera especially if you have large hands.
