Ron,Thanks for the info, I do remember now about what you're saying. I saw the older version on eBay and was curious about it. It said it was hsm, but I remember the controversy. So I guess I'll...

Ron,Thanks for reply. One version that I'm looking at is f4 with hsm the other version/newer version is f4.5 with hsm and OS. What I'm trying to determine is is there any image quality...

Is there any significant difference in image quality between the Sigma 50-500 f4-6.3 hsm vs 50-500 f4.5-6.3 with OS? I'm thinking about buying a used one and I'm trying to determine what to buy...

I tend to use the square crop for portraits especially if I make prints. Portraiture normally isn't my thing, so I have no real experience in that area. But for some reason it just seems to work...

My mistake, didn't realize it was a waterproof point-and-shoot.

I wonder which lens was on it?

You're right, they are juveniles, didn't see them flying. Thanks for the comment, you're right I have to work on white balance and highlights.John

Thanks for looking and your comments. John

These guys seem to be favoring a tree in my front yard.

Thanks guys, for looking and answering. A wren it is.John

I know very little about birds. This tiny little guy with a very loud voice has made a nest in a woodpecker notch in a piling in my backyard. Pictures were taken with my 60-250 and heavily cropped....

The distortion and no readable focal length (what's the big secret?) bothers me also.John
