Strength:

Very easy to get started with, reasonably priced
I have been getting excellent close up shots photographing people at fairly close (>10ft. away) range even zoomed all the way in (300mm)

Weakness:

No image stabilizer not overly pleased with auto focus over long distance zoomed all the way in (300mm) I have camera armor and it's a little tough getting the lense on, must pay close attention and align everything up exactly

Very intuitive to use, took a little getting used to that both the zoom and manual focus are rotational (my old zoom slid back and forth to zoom) I purchased for outdoor / sports and am looking forward to using for Special Olympics Alpine Events

Light,58mm filters,great color,sharp, great macro shots at 300mm with a tripod,price

Hard to find a hood for it

What a pleasent surprise.Great zoom for any price.Size and weight makes it easy to hand hold for sharp pics at 300mm at 1/250.Great color.Beats the heck out of my Nikon 75-240mm which I sold on Ebay for 40x the price.

Strength:

well made cost pretty good optics

Weakness:

wish it were faster

I bought this lens to take mostly sports of pictures of kids. The lens is well made with a stainless mount and good dampening. It is heavy and as a result autofocus is OK but can hunt at 300mm if you aren't rock steady with the lens. Reasonably good optics and a good value. I now know why you can get $thousands for a fast 300mm lens.

Strength:

Excellent value!
Clear, sharp pictures from high-quality glass.
Lightweight & compact for a long zoom.
1:2 macro!
Works flawlessly on my Pentax ZX-30.

Weakness:

Auto-focus sometimes needs help at long focal length.

This Quantaray lens is manufactured by Sigma for Ritz Camera. The Sigma version of the same lens was $50 more expensive than the Ritz version. I was so impressed by the quality of this Sigma lens, I bought one of their 24-70mm to complete my beginner collection of lenses (wasn't available with the Quantaray name on it).

$250 would still be an exceptional value for this lens! The glass is clear, the autofocus works well enough, the macro setting produces clear and sharp images, and the zoom barrel is nicely dampened. This lens just produces great pictures!

If you're a beginner photographer on a budget, this is a great acquisition to get you into sports and nature photography.
