Any experience of OM lenses on DSLRs?

I know there's a number of posts about the OM 4/3 adaptors, but I wondered what results people are getting with old 35mm lenses? Focusing I guess is a major issue? (No camera iris or focus control.)

I've read that you should not shoot wide open or closed, but otherwise I would imagine the resolution should be pretty good.

Looking to buy an adaptor from 'Enjoyyourcamera.com', 30 EUR, unless anyone's had bad experiences with it...

Re: Any experience of OM lenses on DSLRs?

I have two 3rd party 4/3rd to OM adapters.

One is on a Clubman 28mm F2.8 Macro 1:5 lens and the other is on a Tokina SD 28-70mm F3.5-4.5 lens.

The adapters work very well.

In Swindon there is a small camera shop (Gilberts I think). They sell new and old lenses. I picked up both for about 25.

The stock 14-42mm lens is much better than old OM lenses, but the macro lens is rather good. In my gallery there is a picture of apple. This was taken using the Tokina.

If you have the lenses, why not play.

Re: Any experience of OM lenses on DSLRs?

Is the DSLR kit lens really better than good (ie. Olympus) 35mm primes?

Re: Any experience of OM lenses on DSLRs?

Hi there.
I use the 2 kit lenses and the 11-22 with my E400. I have also tried 3 different Hexanons, a Nikon lens, a Vivitar, a Takumar plus some other cheapies (Pentacon etc)

I have to report that the modern Zuiko zooms are indeed better wide open than most of the above lenses. I think this also applies to OM legacy lenses.

However there is little to chose between new and old if you stop down to f5.6 f8 and beyond.

You may well need a split image screen (Katzeye for example) in order to focus accurately.

The advantages of legacy lenses? They feel well made compared with modern plastic lenses and you can get a good low light lens (f1.8 f2 etc) for peanuts. An E400 with a compact Tamron has a nice retro look and feel, a bit like a digital OM perhaps...

I have a web page with basic test chart shots from many of my legacy lenses which might be of interest..

Hope this helps :-)

Re: Any experience of OM lenses on DSLRs?

If your camera supports live view, you can zoom in using the dial. This is really useful when using old lenses.

BTW, I was reading an older E3 review recently and the review mentioned about using the dial to adjust the live view from 7-10x. I just tried this on my E-510 V1.3m firmware and it works.

I have tried two of the cheaper split focus screen on my E510, and they are not bad for the pice, but I have switched back. The Oly focus screen is clearer, and is generally better. I have not used the Katzeye screen due to cost.

I also found that the camera AF and live view focus was different to the split screen. It was small but noticable.

The split screen also made any astrophotography very hard.

Anyway, back to the thread.

The adapters work well, with limitations. The newer Oly glass/plastic lenses are very good (IMHO)

Re: Any experience of OM lenses on DSLRs?

I use a lot of 'legacy' lenses with my Olys and agree with the last two posters.
Apart from a bit of fun there are some great and outstanding quality lenses out there to be had for very little money. Fast glass is relatively cheap (although there are issues using them wide open - search and see and look at Saar for a start) and pretty well anything can be made to fit a 4/3 camera. Of course if you want very wide angle then your better of with the new lenses, or perhaps a 5x4 .

Re: Any experience of OM lenses on DSLRs?

I'm a big fan of Russian M42 lenses, my favourite being the classic Jupiter 9 85mm f2. Fixed lenses are tiny for what they do, and it's amazingly liberating to work with a 170mm f2 equivalent that costs less than £60. Focus is a pain (less so for those who those who grew up with manual focus film cameras), but good eyesight and a bit of practice pay off eventually:

Hi there..

Actually I am holding a Jupiter9 85/2 in my hands right now. Its hidden secret is the 16 (or more) blade diaphragm!! This one doesn't seem to have coated optics and when I tried it on the e400 it seemed very soft wide open.. Rather like the Pentacon 50mm lenses, it is very sharp if you stop it down enough..

Re: Any experience of OM lenses on DSLRs?

I suppose it's a bit soft, but that's never really bothered me. And it gives a nice glowy feel when converted to black and white (which is what these lenses optimised for). Don't know whether my copy is multicoated, probably is as it's a relatively new one - but it's sharp enough for me. The biggest problem for me is focusing exactly on the spot I want - the f2 aperture doesn't leave much margin for error. 100% crop: of the above:

Re: Any experience of OM lenses on DSLRs?

Agreed, I don't mind a little bit of soft wide open, as long as you know its there and as long as it goes away when you stop down one or two stops..

(BTW - My secret weapon is the Nikon Series E 100mm f2.8. I can and do use that one wide open without regrets...)

As for focus, I swapped my screen for a Katzeye (expensive but excellent) and that helps me focus lenses wider than f4. To use the split image and microprism you need to have the eyepiece diopter set exactly right for your eyes IMHO...

Excellent bird picture by the way :-)

Re: Any experience of OM lenses on DSLRs?

Very inspiring stuff! I think I've got some old Nikon lenses as well. Must get a mount, dust them off and have a go too.

Is the focal length equivalent on the 4/3 system? Or does an old 28mm legacy lens give you same as a 14mm on a 4/3 DSLR?

Re: Any experience of OM lenses on DSLRs?

If you put a 28mm Nikon lens on your 4/3 it will act just like an Olympus Digital 28mm lens (if there were one). So no tricks there.

However - either lens will act like a 56mm lens would on a 35mm SLR. You might remember 28mm as a wide angle from the old days, but on a 4/3 it comes out as a standard lens..

Re: Any experience of OM lenses on DSLRs?

Surprised no one has mentioned John Foster's useful tests of OM lenses:
http://www.biofos.com/cornucop/omz_e1.html and http://www.biofos.com/cornucop/omz_e330.html

This Flickr group may also be of interest:
http://www.flickr.com/groups/om_four_thirds_adapter/

I found legacy lenses almost unusable on the E500 because of the small viewfinder, but a KatzEye screen made it more feasible. I was still irritated by the faff of focus, compose, stop-down, and shoot however. I thought I'd left that behind with my Practika IVF... One of the reasons for going digital was having AF, so I abandon it with reluctance.

I did a few experiments with Live View on the E510, especially with macro using extension tubes, but I was never very happy with them. The only image I really liked was with an old Sirius 500mm mirror lens (http://www.flickr.com/photos/hughofb...ld/1452548334/), but achieving optimum focus wasn't easy, even with LV. Why is it that Oly won't do a firmware update with Focus Confirmation. Allegedly the Russian Dandelion chips and experiments on DP Review show it could be done...

I find the brighter viewfinder of the E1 a good deal easier to work with and will persevere with my few remaining OM lenses.

I understand Hexanons have a number of fans (http://www.buhla.de/Foto/Konica/eKonicaStart.html) - including one I've seen described as "the sharpest lens ever made..."

Re: Any experience of OM lenses on DSLRs?

I use the adaptor to connect to my OM Bellows with Macro Lenses and this works very well. The results are as good as scanned film and considerably less expensive.

At the other end I have also attached a Sigma 600mm Mirror and just to see if it would work a 2x converter. Thats a 2400mm equivalent and it actually produced an image that was better than I expected (better than anything I've seen from a phone camera, holga, lensbaby, etc...)

So if you have some good glass, and like to play, then go for it. If you don't like it, sell them here or on ebay

Have fun

Graham
