By focus assist do you mean the automatic magnification to ease manual focus? It works everytime with my GF1 and cheap adapter. Press the “wheel” on the back and you get zoom, manual focus, and then press the shutter release partially, it goes back to un-zoomed for composition.

Btw what is the firmware version number of your GF1? Because this feature is only available after firmware 1.1 update. Could it be you have older than 1.1 firmware on your GF1
The GX1 has the same feature. Thanks for the information! I got my Konica-m4/3 adaptor in the mail today, and was fiddling with my GX1 w/o lens to make sure I could use the focus assist. You can also tap the screen with this camera (and, one might assume, the other Panasonic touch screen cameras) to enable the feature.

Now my Konica 28mm f3.5 hexanon just needs to arrive!

OM to M4/3 - technique to keep the viewfinder at full luminance when stopping down?

I do apologise if this has been addressed previously. I have recently taken delivery of an Olympus MF-2 adapter and have an OM 50mm attached. The OMD-E5 set to manual, focus wide open (f1.8) but when the aperture is stopped down the viewfinder dims making it difficult to confirm focus just before pressing the 'shutter'. Is there a way to overcome this, i.e. to keep the viewfinder 'bright' when the lens is stopped down?

Um, it's a fully manual lens and you've got a live view camera. Meaning that if you stop down the lens, you cut down the light and darken exposure unless you bump up the shutter speed (in full manual mode). If you shoot in Program (O) or Aperture priority (A) modes, the camera will adjust exposure to compensate for the drop in light.

Also, you do not want to be checking focus *again* with the lens stopped down. My order for shooting adapted glass (usually on my 5DII, very sometimes on the Oly):
- Aperture priority mode
- Open aperture as wide as it will go, and focus
- Stop down, meter and shoot (auto-exposure set to half-depress of the shutter)

This stop-down metering approach takes seconds. No point to 'confirming' focus with the lens stopped down, just pop open the aperture and re-check if necessary, then twist it back down. If you're a little worried that you're not stable enough to keep the focus where it needs to be when you stop down, do some focus bracketing (shoot, shift focus back a little, shoot, shift focus forward a little, shoot). It takes some practice, but it is a lot of fun. I do wish the E-M5 had focus confirm chips, though...

Many thanks Mattia, that's clarified it for me. I thought I'd read somewhere that the viewfinder compensated to keep the image bright, I must be imagining things.

I have another question (bloody newbies, ah!): when coupling the OM lens to the adapter (MF-2) it clicked into lock, but the MF-2 doesn't appear to have an unlock button, so is it simply a twist anticlockwise to remove the lens from the adapter, or is there a hidden unlock button? Hope that makes sense!
Many thanks.

There are two tabs on an OM lens. One is for DOF preview, which is disabled on an adapter. The other is the lock release for the lens. It's become second nature for many photographers to squeeze both to remove the lens, and you forget one is a lock release..

Most do have viewfinder compensation. My g3 does, unless I do a shutter-speed preview. It doesn't upgain in the magnification though.

You can turn VF compensation on in the Ily bodies as well, but I don't like it because 'ruins' the accurate exposure preview pre-shot. May be handy for critical focus in poor light.

Usually I just use the histogram display to help with the exposure settings. YMMV.

Hi there, newbe here.

I recently got me a GX7.
I have this Minolta AF 75-300mm F4.5-5.6 D from 2001.
Subscribe to see EXIF info for this image (if available)

Do you think it's worthy to get an adapter for that?
And which one to chose?
I looked on the Bay but don't know which to buy.
Help please.

It's an AF lens with no aperture control, so I wouldn't bother. It might still work natively on a Sony alpha mount DSLR/SLT.
Thank you mattia.
I thought about occasionally using it MF because my main thing is macro.
The adapters I saw on eBay are very cheap so a little experiment with the `beercan´ seemed easy.

Can MFT mounts deal with weight of big legacy lenses?

I'm a new member of Mu-43 (Hello everyone!) with a pretty basic question. Yes - I did search the forum, and I could find nothing; forgive me if I overlooked the answer to this question.

I have an Olympus E-PM1 and I want to use my old (from my film-days) Sigma 70 - 210 mm EOS mount lens. I'm aware of the hassles of using EOSlenses on the mft - I'll deal with them. My concern in more basic: Can the PEN lens mount and tripod support adequately deal with the weight of a legacy 70-210 zoom? It is sooo much heavier than the camera that I worry about the stress on the lens and tripod mounts. If I'm hand-holding the lens I will usually (but not always) have a hand supporting the lens, but if I'm using a tripod or monopod I might not. Do I risk damaging my camera?

Thanks for any insights you can provide.

I recently bought a Nikkor 105mm f2.8 Micro (MF) in a local charity. £30. What's the best adaptor for MFT? Or is this focal length too much for MFT - it would become, effectively, 210mm. All suggestions welcome.

You don't say which 70-210mm lens it is, it comes in various versions, some lighter than others. If it's the f4-5.6, it shouldn't be an issue at all.

Pretty much any adapter from eBay will do, but if the lens is in excellent condition, you might want to stay away from the absolute cheapies. There is no lens made that is too much for MFTs. A longer FL macro is actually good, as it provides working distance between yourself and the subject.

Thanks OzRay. I was thinking of a good quality adaptor as I got the lens so cheaply. And yes, it is pin sharp and I've yet to put it on a tripod.

My father just gave me 3 of his old OM mount lenses. The first is an Access 80-200mm f/4.0 Macro, I can find no mention of this lens anywhere. Next is Sigma 39-80mm f/3.5 Macro which is also a mystery lens. And the last on is a Vivitar 55mm f/2.8 Macro, which is listed in the Adapted Lens Sample Images. So does anyone have any info on these lenses?

I will be purchasing an OM to m4/3rds adapter when I eventually get home. At home I also have my old OM1 lens, a 50mm f/1.8 and a Focus(?) 105mm(?) f something. So it looks like I will have a bunch of "new" glass to play with.

I have the Vivitar 55 Macro. Great option, as it has 1:1 built in, and the front element is so recessed, it is the only one I don't have a UV filter on. It is a bit odd in the fact that once you get close to MFD, the distance starts appearing vertically, as the focus ring turns more than 360deg, and they ran out of room...
