Wow, I always thought the Kiron 28-85mm 2.8-3.8 "StovePipe" was sharper!

So did I, and was hoping I didn't overpay for it. Guess I didn't!
Personally my budget has kept each and every single purchase (camera aside) below $100CAN save for the Sigma 24-135 which was a tad more at $150CAN. But interms of image quality, I'm sure this can easily lay waste to many of the more 'coveted' autozoom offerings from other companies (Canon and Nikon is a good example given their very high cost premiums.) I had a couple Nikon users including a D200 shooter revel about how sharp the Vivitar was so I guess I'm not alone in that thought.
Originally posted by seeker Do you still lose focus when you simply recompose the frame without changing the zoom? I was thinking of a situation where I put the subject in the middle of the frame, focus on the subject, and then move the subject to the side of the frame without zooming in or out.
I've done it before at parties and large gatherings and I don't quite notice it. Technically you shouldn't really. Think of your focal length as the 'radius'. If you focus for 2m metres/6.6 feet, then everyone in your picture that's standing on the 'circle' will be in focus. So in others words, you should still keep focus because the distance between you and the person you want to take a photo of remains unchanged.
Originally posted by seeker Thanks again, and I so look forward to playing with the lens! Glad to hear that it's sharp at all apertures, as I don't like to use the flash and take a lot of shots indoors.
Sometimes you'll need the flash though because indoors doesn't always offer adequate light even for a 2.8 aperture, but if you do it right, the photos are still every bit as good as shooting in availiable light if not better. I use a manual flash so I gotta literally almost guess and check at the settings.
