Does anyone know when the new 50-200 SWD lens is supposed to be available? I have a trip coming up in 45 days and wanted to have the new lens but am running out of time. Should I just pick up the old 50-200?

Also, any speculation on price differential between the two?

err... that's prob the old one :(

still looks like a killer lens!

it is still a great lens
the new version will have much faster AF

Thanks for the replies!

So, any ideas on availability for the new one? I've been searching for release date info from Oly, Zuiko, 4/3, but haven't found anything yet.

Gotcha! Well, that timing would rule out the new 50-200 for now then. But I still need to get a bigger zoom for my upcoming wildlife trip. Does anyone know about the performance on the Sigma 135-400? It's modestly priced and will get me much closer to the action than my 40-150 which is good, but will I be sacrificing too much IQ with this lens? I'm an amateur and I don't need a high-end pro lens, but I also don't want to go all the way to the other end of the spectrum either.

Other lens' I have been looking over are the Zuiko 18-180 and Sigma 50-500, but the weight of the Sigma is almost 5# and I'd still need to add a teleconverter on the 18-180 to get the zoom, so it looks to me like the 135-400 would be my best bet. Any suggestions/recommendations would be great!!

Personally I have do not have either of the longer zooms you are looking at. However, for wildlife (and you don't say what type, big or little, or how close you might be) you can NEVER have a long enough telephoto. I have never found that the difference between (35mm equivalents) 300mm and 360mm to be all that great. I believe that most people do not notice much difference until they come close to doubling focal lengths. Let's face it your expectations are probably not based on such small percentages. A 180mm is only a 20% gain over a 150mm. Do you see people arguing over the difference between (35mm equivalents again) a 50mm and a 60mm, also a 20% difference. While I like the forums here as they are generally less frenetic (and friendlier), the folks on those at dpreview (http://forums.dpreview.com/forums/forum.asp?forum=1022) will get all pixelated over every lens. There are also some great samples there as well.

Thanks kgosden, you make a very valid point. Even if I buy the 1.4 teleconv too the 180 would still only stretch to 250 (dig.), which is exactly 100mm over the 40-150 I have today. So it would cost me about $775 (400+375) to gain 100mm whereas the Sigma lens runs about $600 and would get me 250mm more. Price and extra zoom-wise, the Sigma wins. And the 135-400 would be the perfect range for me and nicely complement the range I already have with the 14-45 and 40-150 kit lenses. So all that I really need to know is whether it's a good lens... I don't think dcresource has reviewed it yet, so I'm off to see if I can find more info. Will report back (in a new thread, sorry for the hijack Riley) what I find.

is this an example of the Sigma you are interested in ?


The Sigma AF 135-400mm f/4.5-5.6 APO Aspherical RF is not a perfect lens nor can you expect that a budget lens reaches high end quality levels. Nonetheless it is capable to provide very decent results especially in the 135-300mm range. At 400mm @ f/5.6 the quality is quite soft but from f/8 and up the quality is very respectable. The distortion characteristic is almost perfect and vignetting isn't really field relevant on an APS-C DSLR. CAs are a quite pronounced at 135mm but the overall level is still acceptable. Mechanically the lens leaves more to be desired. The quality of the used materials is fine but the friction of the zoom ring is way too high and the worst implementation that I've seen so far. There's no such thing as a free lunch but admittedly the Sigma offers quite a bit of possibilities for your bucks.
