    Has anyone used the Sigma 150-600mm contemporary on the E-m1, (either versions)? I would be interested to see and hear of the results please.

    Wish you hadn’t posted that :D, I’m periodically tortured by my GAS tendency to buy a Metabones adapter. Thus far I’ve been able to dismiss it as a vanity project but I’m not sure I can withstand the pressure!

    We have a new observation wheel in Chesterfield for a few weeks. I'll try to get onto it at some point, although I'm not exactly sure what there is to see :LOL: Here's some pics of the wheel for now.

    Still not sure why my Olympus images appear soft when posted from Flickr, I've tried posting different size images but it doesn't help :(

    that wheel reminds me of a friend of mine who bought his wife a Hamster fur coat, she absolutely loved it and everything was hunky dory until they went away for the weekend to Blackpool,she thought she would show off her new coat and all was good until they went to the amusement park,
    no matter how he tried he couldn't get her off the big wheel :LOL::LOL::ROFLMAO::ROFLMAO: :olympus:

    A few years ago I went to a free Olympus try it and see type of event where I got to try out different lenses and lighting set ups and have recently re-edit some of the photos from it so I thought I'd share them. I know they're far from perfect but it wasn't a proper studio session, just a 'try this and take a shot' kind of scenario.

    I see 1 was with the 75 and the others 45? Did they let you use the 75? Did you rate it much over the 45?

    Didn't really get chance to put it through it's paces tbh as both were stopped down for the majority of the shots. Certainly stopped down it's very good, but then so is the 45mm. The 75mm is in a different league build wise though, feels like a proper pro lens rather than a bit toy like.

    I've just got back from a trip to Costa Rica and realized how many shots I missed because my Oly 14-150 didn't quite have the reach. Has anyone got the 75-300mm 1:4.8 - 6.7 II, and if so what do you think of it? Would it be a good buy?

    I've never used the 75-300mm but i do own the Panasonic 100-300mm F/4.0-5.6 Mark 1 and i find it suits my needs well.

    It's faster, and reviews online seem to suggest it's sharper too.

    I had both the Olympus 75-300mm and Panasonic 100-300mm. Both are 'ok', IQ is about on par with the 40-150mm f4-5.6, although for me that Panny was a touch sharper at the long end. The panny obviously lets more light in too but is noticeably heavier. Both struggle in terms of AF at the long end, a lot of hunting (this was on the EM5-II).

    How does it compare in terms of CA/fringing? I find the 40-150 4-5.6 is terrible if you shoot into the light, blue fringing can be very strong. I've been pondering on one of the 300mm zooms for a while as I need more reach, but I think the 100-300 mkII is the best of them and is pricey enough, for me at least. DXO mark have the Olympus 75-300 mkII down as sharper than the original 100-300, they don't include the mkII of that which leads me to think it's optically identical?

    I've never noticed CA's particularly on the 100-300 or the 40-150mm, but then I don't shoot much with the 40-150mm. My own observation, and every other user review I've seen would disagree with DXO, but YMMV.

    I only started to notice it more so just recently tbh, since that ball of fire in the sky has begun to show itself and provide back/side lighting. Maybe I should get a hood for it to cut out some of that strong side light when shooting through the window.

    Can’t see how a hood will stop CA’s tbh, flare yes but not CA’s?

    Yeah sorry, I've experienced some flare also. The CA I get is strong blue when I shot say, a bird on a tree with strong back lighting. Flaring only happens when I shoot through the window and there's strong side on sunlight, but this can happen with any lens


    CA = Chromatic aberration. Blue or purple fringes around the edge of your subject where there's strong highlight backdrop. Usually seen on tree branches, or in my case, around the edge of small birds on those branches

    This would be a severe case:

    I’ll do some testing with my 40-150mm if we ever get any sun this year and see what my findings are. I thought all Olympus lenses had corrections applied automatically in the RAW files though?

    Is that not Panasonic? I know they do corrections in cam, not sure about Olympus. The CA I have experienced isn't near as bad as the example above, but it's been noticeable enough. I'll see if I can find any examples from my own folders - I do tend to delete the RAW folder after I've done with the edits of that batch. I am using an old em5, maybe on later models they introduced corrections?

    Hmmm, reading around it does not appear that Olympus apply CA correction, only geometric distortion such as barrel distortion. However, I’m yet to find anything conclusive.

    I should probably try some kind of comparison test using the lens on both the Oly and Pany bodies I own, but I'm a lazy SOB :D I think Panasonic do correct, but only for their own lenses, and with Olympus there isn't any in body correction. But just on the CA front, it might be interesting enough to compare different bodies with the same lens

    The consensus is that Olly definitely correct barrel distortion and the like.

    Oly bodies do correct CA, they are automatically applied even with raw files although that can sometimes not be enough in extreme conditions (my 17 1.8 springs to mind). Never noticed CA on my 40-150 though and certainly not that bad.

    Something in my head is saying on lateral CA (purple/blue) is corrected and not vertical (green/red) or maybe they other way around.

    Edit: they definitely apply distortion correction, that’s vital for the lens design which are designed on the assumption you can correct so they can focus on other qualities.
