Re: Canon FD Telephoto

I've used both around 20 years ago, they were okay optically but each had so much backlash in the internal focussing I struggled to focus them.

Re: Canon FD Telephoto

Sigma 50-500mm (Bigma) in Four Thirds mount with a Micro Four Thirds adapter. You will have full metering and AF, albeit rather slow. However, you would be focusing the Canons manually anyway and would be restricted to aperture priority and manual exposure modes only.

I have one of these and have tried it on the E-M5, and yes I can confirm that focussing is seriously slow. My concern though is that is finally comes to focus in a staccato series of small steps back and forth, which is of course what you would expect from Contrast Detect AF.
It sounds a bit like a machine gun; The AF motor is fast, which leads me to worry if the sudden alternate shock loadings will have a detrimental affect on the gears etc.

By the nature of the lens, it wasn't designed with CDAF in mind and will also likely be out of warranty as Sigma stopped supplying them a while ago.

I wonder if prolonged CDAF use will lead to expensive repair bills; I have read complaints that Sigma don't keep many stocks of spares for the Bigma in the UK.
I also wonder about any weak point which is found by the machine gun effect will lead to a spares shortage in Japan as well.
Unless Olympus/Panasonic/Tokina release something interesting soon, more and more folks will realise that the Bigma is the only current affordable option for a long m4/3 lens with AF.

I do hope we don't see a rash of Bigmas failing prematurely.

I've been meaning to contact Sigma to ask about this, but not had chance yet.

Possibly also

Tokina 300mm F2.8 Manual Focus with a 1.4 converter

Tamron 350mm SP series mirror with a 1.4 convertor, assuming you can live with the doughnut bokeh
(I wouldn't bother with the 500mm Tamron SP varient)

I do have these options to try some time, but not enough hours in the day at the moment.

Re: Canon FD Telephoto

I was listing fast legacy glass longer than 300mm. If a fast 300mm would work there's the following.

Tamron 300mm f/2.8 (there was at least 2 versions)

Nikkor 300mm f/2.8 IFED

There are two versions of the 500 f8, the model 55BB is later and better.

The 1.4 converter is apo.

Re: Canon FD Telephoto

Raj, I have regularly used the Canon EF 400mm f5.6L with both the E-M5 and M1 with great success. It is a superb L series lens still in production but as it has been around for over 20 years it can be bought used for a good price. It also works well manually focused with the Kenko 1.4x converter giving an EFL of 1120mm! In addition it is quite small and light for a lens of this quality and can easily be used hand held with the excellent OMD IS.

With the Metabones Canon EF Lens to Micro Four Thirds T Smart Adapter Canon EF lenses can be used with the EM-1 in AF mode. AF is very accurate, AF-S is reasonably fast, AF-C is slower and officially not supported by Metabones (although it sort of works). I borrewed such a setup and did some field tests that convinced me this setup is a serious option to consider and at a reasonable price tag as these fine 400/5.6 lenses have no IS and therefore not so popular/can be found at attractive price points. The EM-1 IBIS comes in handy here.

Some samles can be found here: http://e-group.uk.net/forum/showthread.php?t=40178

Before returning the lens I did a quick test on the E-M5 and it worked. AF acquisition was slower than with the EM-1, in par with what you would get with SWD 4/3 lenses on E-M5. The AF seemed very accurate.
