An exposure meter should only be used as a guide. Your eyes should be the real judge.
Hugo600si: No stabilization for Sony, wake up Sigma and smell the e-mount! Its a mount with high opportunities and limited lenses in their segment... hope they turn around on the no OSS for Sony.
Sony usually have Shake reduction in the bodies so it doesn't need to be in the lens.
I'm personally not too worried about the Sigma 24-105mm f4 as I already use the Nikon 24-70mm f2.8 but if it's made as well as the new Sigma 120-300mm f2.8 Sport lens it'll give the big boys a run for their money.
I work for Jessops Brian and we spoke about this very thing. I would like to see it but would Nikon and Canon open up on the high street? Could they afford to? Possibly Sony or Panasonic perhaps. If anything, camera gear will now increase in price (IMHO). When was the last time you got a real 'deal' from Apple? They set their prices and very rarely move from it.
I've had one of the Samsung Galaxy cameras since October and LOVE it! It does everything I need it to do as a point-n-shoot camera with great interaction with social media.
munro harrap: I use a 1Ds MkII. I cannot get good lenses for it. I have returned a 17-40mm, a 100-400mmL, and a 70-200mmL recently, and have tried out four 24-70mmL-none of which is as good as my old 24-85mmUSM, and have tried out 3 24-105mmL, lenses and bought 2 which were returned, as like the tryouts, they were soft and quite hopeless at the longer lengths across the frame.
So I fully understand the current problems Canon users have, none of which a new body addresses. The lenses are poor.
I am saving for a new machine, but why bother? as without the optics to match there is little point. Dealers box them so badly they get damaged (must be deliberate- you cannot do that by accident) .
Some lenses may be OK, but this new machine needs lenses that cover 35mm not the EF ones designed for cinema HD 2 Megapixel formats, and everyone is waiting for those. At the moment, its a con.
I'm in 'the trade' and get a lot of people say the same. It annoys me a little that it's always the lenses that get blamed. I've been to a factory in Japan to see how these lenses are made and how each and everyone is hand assessed.
A friend has a 7D and she kept blaming her lenses. Letters and emails went to Canon and after taking it all to a repair center it turned out it was actually the body's sensor that wasn't flat to the lens mount. It wouldn't have mattered what lens would have gone on the body, the images would have been soft.
To me, if you have 4 L series lenses which are 'hopeless' and a 24-85mm which is OK, you just have been lucky with that lens/body combo.
I've had customers try numerous lenses on a body in my store only to dismiss them. My advice is get the body back to Canon and send all your lenses too and get them all set up together. I'm not saying some lenses are not out, but to get 4 all out, I would start looking at the camera IMHO.
