This review is from: Canon EF 70-300mm f/4-5.6 IS USM Lens for Canon EOS SLR Cameras (Camera)
The short version:
Pros: The optical quality is great, the speed is terrific, and it compares well to the 70-200mm lens that people like to say blows this out of the water (I believe they are wrong - but we will get into that later) and finally, the price cannot be beaten. Buy it.
Cons: No hood, extends as it zooms, and the quality of the picture in low light situation lessens a little.
The long version:
I am writing this in simple terms. I found several, several reviews on this lens but they were all in technical terms and leaves you scratching your head a little. So, if you are like me maybe this review will help you.
I bought this lens a couple months ago from US1Photo.com (check these guys out. They regularly have significant sales and terrific customer service). I use this lens with a Canon 40D.
I take several types and styles of pictures so I needed a lens that would do the best job at several... Read more

I bought this lens as a replacement for the earlier 75-300mm IS lens. I was generally happy with that lens, but it had definite limitations - I needed to shoot at f8 or f11 and bump up the ISO to get a decent shutter speed. This new version seems sharp at full zoom even wide open, allowing me to use a lower ISO setting. Size is similar to older version, but the IS seems more effective - looking through the lens when it kicks in you can actually see the image become more stable and less shaky. I got this over the Canon 70-200 f4 L because of the extra reach, smaller size (slightly) and the images I've seen from both are very similar. UPDATE: There have been reports of soft images when using this lens in a verticle orientation - however I have not experienced this on my copy. I'm happy to say that after months of using this lens, I still consider it great.

After debating between this and the 70-200 L series I decided to purchase this lens. I have been pleasantly surprised by the results. I also own the 17-85 and the 50mm 1.8 lenses and I have found that I have gotten the "most pleasing" results from this lens. The pictures have been very sharp from my 20D - even in the 200mm - 300mm range. I've also been happy with the quality of the bokeh.
The primary drawback I see is that the AF tends to hunt a fair amount when confronted with low contrast images. That being said, I used it for some flying bird shooting at the wildlife refuge and was surprised to see how many of the shots were in sharp focus. However, it was a little bit of all or nothing. Several shots were also wildly out of focus. Since the lens is fairly slow to focus, you never know what you're gonna get with such a fast moving object against the distant sky.
I had much more consistent results when shooting soccer, softball and football in the park... Read more

Each wipe is in a foil-lined wrapping, which makes them last longer because they don't dry out from sitting around. That's a nice touch.
It has to be remembered that these are WIPES...not wash-cloths. You take one out, give a wipe, and you're done. The wipe doesn't last any longer than that. If you expect more, then your expectations are unrealistic.
The box says "High-tech ammonia-free formula", so who knows what's actually in there. It's pretty clear that on my multi-coated filters, the wipe's solution hasn't damaged the coating, so I'd say it's plastic-safe. It probably is, or is a variant of, electronic contact cleaner, which removes grease, dries without residue, and is plastic-safe. I also use the wipe to clean spill-droplets off of my computer monitor (I'm a messy eater and it's a 30" monitor...lots of area to catch flying debris!) These clean the soft LCD without any problems.
I find that for lenses and filters, it's best to practice a... Read more

This review is from: Zeiss Pre-Moistened Lens Cloths Wipes 200c (Health and Beauty)
The first time (or even second time) you use these wipes expect a bit of smearing. What it appears this wipe is doing is removing old residue from whatever previous cleaner you used. Once you get the old muck off your lenses these wipes will keep the optics perfectly clean.

When I got the wipes, I first tried them on my glasses and my glasses are the cleanest I've ever been able to get them, crystal clear. I then tried them on my MacBook Pro screen and the same is true. No smudges nor scratches nor residue. The instructions say to first lightly brush the lenses with the closed pad to remove any grit (the dampness removes it), then open the pad and clean the lenses. They do dry quicker than other products but I think this is an advantage. With other products, you tend to put too much cleaner on the lenses and then rub and rub to dry them and get the smudges out. These Zeiss wipes dry out relatively quickly, smudge free, so that all the extra rubbing is avoided reducing wear and tear.
