I am looking at the Sigma 10-20mm to do panos and?wide angle shots with.? I am using a Canon 50D.??Will the lens give me the right perspective for shooting panos?? I currently have the Canon 28-135?which causes me to be too far away to do street shooting.? A penny for your thoughts.? 

Thanks in advance for your time and assistance.

For your use (what you listed) I would go for the 5DM2. It's clean and the detail is superb. Right now it is too early to talk about the 7D unless you want to base on white papers; more time is needed for common people to test it. 7D is aimed to sports, of course it can do everything but panoramas won't be stellar since the crops won't give you real wide angle or circular fish eye unless using crop lenses. In that moment, you will have to stay with "all crop" system or perhaps have double lenses. 

My path started with the 30D, EF L lenses for long time, then 40D and latest the 5D2. I suggest to focus on glass, bodies are disposable while glass will stay with you. The 16-35 L is simply breathtaking for panos.

Hi all,

This time I *must* upgrade my kit. It's a requirement for a job I landed and the budget pays for it. HDR, partial panoramas, long focal distance.

I currently use a Canon 350D. From the pre-digital era I am a long time Minolta user and have some good glass, flash, accessories.

In the meantime Minolta sold to SONY and the Alpha 850 seems a nice proposition (with reservation about the brand. The memory stick stuff is pathetic).

My 350D kit was used mainly for the production of web-based material, particularly full spherical panoramas (7000x3500). It's still the old Sigma 8mm F/4, complemented with very cheap Sigma APS-C lenses just to have something in the range up to 200mm for the occasional use (and with Hugin I can nicely correct them to perfect rectilinear).

Besides the specific job, my interests have shifted to higher resolutions (large prints) and partial multi-row panoramas for large prints, so I will want better glass than I have now in the range of 20mm-200mm. I still do web-based full sphericals occasionally and if I had to change something for that application it would rather be the lens than the camera body.

>From my starting point I'd have to shell out more money on the Canon to reach the same quality of glass as on the SONY (and if I did, I could as well go 5D MkII?) - and that extra money is not in the budget. The body (including 5D MkII if I wanted) is.

What I like about the 7D is 8FPS continuous mode and 1.0x viewfinder magnification.

The a850 has only 3FPS (but is full frame, and the a900, which I also could still get through the budget, has 5FPS which is better than the 5D MkII).

What worries me a little about the a850 (and a900) is the noise at high ISO (compared to the 5D MkII). But isn't that an even bigger problem for the 7D (with 18mpx crammed on an APS-C sensor)? Anybody has some experience in low light with the SONYs?

Exposure Bracketing seems to be a weakness of both contenders. I had considered a Pentax K-7, but that would be a completely new system with plenty of components to buy right from the start, not just the body. And there would be other brands and models to consider too. I am open for suggestions.

Has anybody made any experience with SONY Alpha 550 and its HDR mode? but anyway, it is not present on the a850 (nor on the a950).

Which brings me back to the original choice: Canon 7D or SONY Alpha 850?

Yuv
