Bigma and EM-1..??
 
Anyone yet tried using the Sigma 50-500 with an OMD-EM1? I've seen one for sale and wondered if it would be a good purchase to match the EM1.

It would be quite a handful on a smaller body I think, but the images would they be worth it??

Cheers

Peter

I have used mine it is easier to use than with my E5 shots are good.

It's super HEAVY.

I had one and it is capable of good images. Best to keep the sun behind you as the optical complexity means that it can suffer from a general loss of contrast (veiling flare). I made a circa 6-inch long cardboard tube to fit over the end and that helped. (The supplied hood is designed not to vignette at 50mm FL on 35mm format so is naff all use on micro-4/3. Even my cardboard tube barely vignetted on micro-4/3 at 50mm such is the diameter of the front element).

The AF is not very fast and, even on the EM-1, has the usual slight hesitancy. I couldn't track racing cars with it so had to pre-focus to use it. It's so big that I used it on a tripod with a gimbal head. Hand-held shooting would be a nightmare.

I sold mine when I got the PanaLeica 100-400mm . If you can afford the PanaLeica, go for that as it is in a completely different league. I don't miss the extra 100mm since I use long lenses for motorsports only and accurate tracking even with 400mm is very hard unless you wind the shutter speed up.

If you are shooting more static subjects the old Sigma may be of more use since it is optically pretty good and getting good lenses at 400mm or above is not easy. I've tried plenty of old manual focus lenses and not found anything that would beat the Sigma. For the price you are likely to pay for the Sigma now it can be a bit of a bargain.

I should qualify this by saying the issue is the tendency for old telephoto lenses to give strong colour fringing when used on digital. This is the result of the interaction with the micro-lenses and optical filters on the digital sensors and would not necessarily be observed on film (for which such lenses would be designed of course). Even my Olympus OM 400mm f6.3 lens gave noticeable colour fringing and that is not a cheapo lens. I never did I direct comparison between the OM and Sigma so I can't say how they compare in sharpness.

Moon shot is an unusual rotation for UK. Hesitate to say its upside down, but how did you take the photo...:confused:

Works OK though...............*chr

Malaysia is also "downunder!" *upsided

EDIT: Embarrassingly, I got that wrong. It is just north of the equator. *shrug *shh *ohwell

MJ224 I see you are still in the flat earth movement!

I thought the same without looking at the home location of Blu- by-u.

*upsided It was directly overhead at that time. and we do get that big pimple on top at our location.:(

That lens was so heavy I had to sit on the floor supporting the camera on my poor eye while holding on to the zoom ring to prevent it from sliding back down.

AF all the way with manual A,S and ISO.

Used Bigma just arrived this morning. It really is a beast isn't it. But nice. Defintely needs a tripod - partly for handling and partly due to magnification. Looking forward to a sunny day and getting to a nature reserve or similar,

Re: Bigma and EM-1..??
 
Am wondering if the Em1 lens flange can hold this huge heavy lens?? And are there any ratings from Oly on the weight limitations? :confused:

That's where you are better to hold the lens & let the camera balance on it instead. If you're dangling the lens off the body then it might strain the mount.

Re: Bigma and EM-1..??
 
I always wonder about that. The 12-100 f/4 is pretty hefty and doesn't have a mount so we have to assume that it is designed to be OK at least that far. Which is nowhere near the weight of the Bigma, of course :)

Re: Bigma and EM-1..??
 
I can't imagine anyone who's handled it themself would try to use this lens on an E-M1 or indeed any camera without supporting the lens itself. It's pretty well unmanageable and uncontrollable if holding only the body. The only likely source for excessive strain would be if someone attached a tripod to the body instead of the lens. If you want to use it handeld, then you need to adapt your technique so you can use the zoom ring (and - if on MF - the focus ring) with the same hand which is bearing the weight of the lens. It's a beast, but a beautiful beast. :-)
