New Olympus EM10 - Is it worth keeping my old EOS lenses.

If your legacy lenses have aperture ring on the lens, then yes. My few US$ adapter has given a new life to my old Nikon ai lenses. It is fun to use (if I have time for the MF shooting)....

If no aperture ring, you might need a more expansive adapter which should come with some sort of a switch (to control the iris, no precise work). Then I won't keep them.

BTW, a 250mm lens would = 500mm on MFT camera which could be very interesting.

The AF speed will be slower with an adapter, the Canon nifty 50 is a good lens, but the Olympus 45mm F/1.8 and Panasonic 42.5mm F/1.7 are just as good across what your equivalent focal length will be and not that much more expensive.

The 55-250 is useful with an adapter it would come out as a 110-500 which is much longer than anything you can get for an affordable price on Micro Four Thirds, but you would have to check the AF speed.

Hi all

I have just bought a new Olympus EM10 (with the 14-42 EZ lens) as I find I seldom take my Canon EOS 550D with me when I go out due to its size.

I have a couple of extra lenses for the Canon as well as the kit lens it came with - a nifty 50 and a 55-250mm is..

I plan to sell my seldom used 550d equipment but wondering if I should actually keep any of it to use with the EM10.

My gut feeling is that by the time I bought an adapter I would have been just as well flogging the Canon stuff and getting a couple of new lenses?

I'd appreciate any advice!

m43 has wonderful, small lenses, I strongly suggest you to replace your old ones with their m43 equivalent.

50mm: since on Canon APS-C it is 80mm equivalent, I suggest you the Panasonic 42.5 f1.7 or the Olympus 45 f1.8 to get similar field of view. Personally, for portraits I prefer the Olympus.

55-250: You may buy the Olympus 40-150 f4-5.6 which is super cheap and has very good IQ, or if the reach is insufficient, there is a 70-300 too. Still, because of size and weight, I suggest the former.

So, with Oly 45 f1.8 and 40-150 f4-5.6, you will have a cheap, but powerful combo, which will fit to your E-M10 considering their weight. If you keep using your old, heavier, bigger lenses, your change to the lighter m43 system is almost pointless.

Thanks all.

I think the fun I might have with an adapter and the old lenses might just end up being a distraction.

Order now placed for an Olympus 40-150 f4-5.6

Off to fleabay with the Canon gear !!

and if you want a nifty 50 its the Olympus 25mm F/1.8

To the OP: But keep in mind, that you won't have the same field of veiw with a 25mm lens on m43 as you had with 50mm on APS-C. As I earlier suggested, Olympus 45 f1.8 would be the best choice for your OM-D.

40-150mm is a great choice. You will be surprised, how light it is.

A lot depends on how good your Canon EF lenses are. If they are top range I think that you will take a large financial hit swapping them for the equivalent M4/3 ones.

Things to consider:

All EF lenses are electronic aperture (at least) and some are fly by wire focus as well.

Metabones electronic adapters can give full function including EXIF and near oem lens AF performance to EF lenses on M4/3 bodies but are expensive. There are cheaper EF to M4/3 adapters that I have heard said work well but of which I have no experience. If you wish to save adapater money then it may be worth researching the various adapters available. Unfortunately there seems to be no serious comparative testing of adapter performance over a wide range of lenses which is otherwise a very subjective opinion.

Cheap mechnical-aperture EF-M4/3 adapters are a waste of money.

If you are coming to M4/3 and retaining the EF lenses it does allow you to change your mind and re-buy into other brand bodies later - this is more attractive if the lenses are of good quality. You have the choice of Canon EF or EF-M, Sony bodies or M4/3 for the same lenses - the M4/3 lenses once bought are only useful on M4/3 bodies as their image circle is optimised for the 4/3 sensor. Plus all the electronic and technical problems of flange focal length - call it impossible - even at crop sensor.

The EF lenses might be (but are not necessarily) larger than their M4/3 equivalents.

If you do buy an adapter EF to M4/3 it does allow you to add further EF mount lenses to you kit if the opportunity arises. Some EF styles don't yet have a M4/3 equivalent yet - long telephoto, and also such oddities as the EF mount Sigma DC 4.5mm f2.8 circular fisheye and the 8-16mm f4.0-5.6 ultra wide.

It would have been easier simply to tell us directly rather than provide links.

But if I read the link references right:

The EF-S 55-250mm will only mount to a plain lensless electronic adapter and not to a focal reduction adapter without physical modification - even then the process is not assured and the lens may vignette when mounted after modification. I have the 55-250 STM (latest) version and it does work very well on the Metabones BT-4 Smart adapter.

Not sure about the 50/1.8 - if it is the latest STM version it may work but my 50/1.8 II version did not work on my adapters (one of the few that don't) and I have not tested it on the very latest firmware to see if it now behaves itself. This is a very cheap lens and might hardly be worth the bother of reselling anyway.

Just tested - the 50/1.8 II still will not AF with pinpoint focus setting on the GM5, however it will AF when used with 1-area focus (most of the time). However the cheap Yongnuo 35/2.0 simply will not auto focus at all and has become my last frontier. The Yongnuo could almost be said to be a clone construction of the Canon lens and makes one wonder if Canon has sold the rights or has been having manufacture sub-contracted out. In any case the Yongnuo lens is not worth the money - which is not very much.

The metabones + 55-250 will not focus as fast as any of the Olympus lenses on the EM-10 so go for an m4/3rds lens

There is nothing lightweight and low price that will match the reach of the 55-250 though so my suggestion would be to look at the 75-300 mk2 (which is available in the UK for around the same price as the metabones smart T)

If you don't mind a heavier lens there are some good deals on the 4/3rds 50-200 ED + the mmf-3 adapter, this gives very good image quality but will be slower focusing than the 75-300 on the EM-10

Yes these are both highly capable lenses, very compact and good value. I suggest that they are on a different planet from the Canon 50/1.8 pot boiler.

I have another thread running which demonstates that the EF-S 55-250mm is no larger or heavier than their closest M4/3 equivalents. That does not mean that the M4/3 lenses are any worse than the Canon lens but it puts to bed the "old, heavier, bigger" argument.


But there are three versions of that EF-S lens and the latest STM version is very well regarded.

You might be surprised Brian. I have the latest Canon EF-S 55-250mm f4.0-5.6 IS STM. Used on a GM5 is is light and easy to work with. The GM5 has eye sensor focus and the lens can be focused almost before my eye to the evf has registered the target subject.

It does help to have the lens pointed pretty close to the target subject when brought to eye as the first up auto eye-focus is only done once. But can be re-invoked by moving the eye out of eye-sensor range temporarily.

However even if perfect focus with eye-sensor is achieved the soft press insists on a re-try to confirm - scope for a firmware tweak back at Metabones? In any case the MF on this quite light for its reach lens is very easy and once set of course the shutter press is immediate and does not need that AF double clunk re-confirm delay.

Maybe it might not be up to birding but then I am not very good at birding with any lens combination.

However I would agree that using an oem lens is more fail safe.

An adapter is always a good investment if the price is not above 50$ (my Rokkor - µ4/3 cost me about 20$). As for your lenses, it all depends how nifty your 50 really is. If it's a F1.4, it'll make a good 100mm equiv. portrait lens. As for the 55-250, it becomes a 110-500, which could be very useful and fun to use will you wait for a Pana-Leica 50-200 F2.8-4... Using your old lenses will help you decide which µ4/3 lenses you really need/want while giving you time to wait for eventual price drops.
