Canon EF 70-200mm f/2.8L USM

Pros: Sharp at f2.8, fast and accurate AF, nice bokeh, focus limiter useful, internal zoom & focus, f2.8 throughout zoom range. Nice to see some accessories included (hood, tripod mount and case).
Cons:
No weather sealing- VERY disappointing for an "L" lens, bit of a lump, but easy enough to get used to.

What the others have said really. A sharp lens, even at f2.8, if you get a good copy. Stopping down to f3.5 shows a slight improvement, but not much: you have to be pixel peeping to notice the difference.

I wouldn't have any qualms about shooting wide open.

The autofocus is very good. It is fast and accurate and even moreso if used with the limiter.

I've coupled this with a Canon 2X mkII extender and the results are impressive. Even wide open at f5.6 the image is far sharper than I'd have thought it would be. Stopping down to f6.3 does improve things, but you need to be zoomed in at 100% to see these improvements.

The only thing I have marked it down on really is build quality. Why it isn't weather sealed is beyond me. And also I seem to have gained a genuine bit of Canon dust and speck of dirt.

It's not the first time I've found such items in a new lens, however, I have no intention of returning it because so far it hasn't caused any problems and I don't know what I'd get back if I did.

It is somewhat irksome though after spending the money on it, and I don't appear to be the only one to have come across it. I wish canon would improve their QC slightly.



 
Canon EF-S 17-85mm f4-5.6 IS USM

Pros: Good IS, good zoom range, fast & accurate AF, produces great colours, can be sharp wide open above 50mm,
Cons:
Distortion from 17-24mm, can be soft wide open from 17-24mm, some CA 17-24mm, dust can enter the barrel (but can be removed).

I've owned two of these lenses now, and am very happy with both (even more so with my new one. The IS started to die on my first, so I sold it on).

OK, so the cons above pretty much sum up the lens: it's weakspot is 17-24mm. Nutshell.

However, you can still get good results, and my new 17-85 seems sharper at 17mm wide open that the old. Maybe I got lucky again, or maybe Canon have pulled their finger out? Who knows...

On a 6x4 print you aren't going to notice the problems, or 8x6. but maybe A4 or above will show the weaknesses.

Stopping down helps a lot at these zoom ranges, but then it takes away the point of the F4 aperature....

The other problem I have come across is dust entering the barrel and sticking to the front lens element. For the brave, it can be removed, but for the weak at the knees, you're stuck with it I'm afraid. It doesn't seem to affect the picture quality however.

Having said that, having a piece of lint attach itself to the inside of the lens was the last straw, and it had to go.

Right, nag over, what is good about this lens then?

The IS is brilliant and makes the lens great for low light photography and night scenes.

It sharpens up above 24mm, much improves by 35mm and above 50mm is generally sharp wide open, but obviously stopping down improves things further. I'd say F7.1 to F8 is a nice sweet spot.

The zoom range is great too, making it a good walkabout lens for landscape photography at the wide end and the the 85mm (135 equiv) is there when you need it.

This is why it is bolted to my camera most of the time and I'd personally recommend it.


 
Canon EF 70-300mm f/4-5.6 IS USM

Pros: Great IS, sharp without stopping down on all zoom ranges (OK, I think I got lucky), price is good for what you get.
Cons:
Roating and extending front element, no FTM,

Ok, firstly I think I must have a good copy of this lens compared with some other reviews.

Through all the zoom ranges the sharpness is pretty constant. There is a difference stopping down, but you have to zoom in to over 100% to see it. And it is sharp. OK, not razor sharp, but definitely sharper than some third party lenses I have seen and owned.

And the IS is brilliant- it is advertised to being 3 stops but I've got some acceptable handheld photos at 300mm with a shutter speed of 1/20s.

The AF isn't that fast, but I've noticed it is faster and more accurate on a 40D compared to my old 350D. It's just a shame it isn't FTM too.

Maybe the build quality could be better, the barrel wobbles a bit at 300mm, but to be honest with the pictures I'm getting, I don't care!

I give it a thumbs up.




 
Canon EF-S 10-22mm f/3.5-4.5 USM

Review Date: Jul 15, 2008 Recommend? yes | Price paid: Not Indicated | Rating: 9 

 
Pros: Good AF in low light, light weight, very sharp even wide open, low distortion (if desired!), good build quality, internally focused, barrel doesn't extend when zooming, fast AF
Cons:
Price! But then again it is a nice piece of kit....

One of my favorite lenses.

For a fish eye lens there is exceptionally low distortion if used correctly, and then on the other hand if distortion is what you want, it's there.

Build quality is good, there isn't any slop (yet.....).

It's sharp, even if wide open, although at 10mm the edges do go a bit soft.

Very useful for landscape photography, museums (and such environments), and if there is a creative side in you that likes the unusual aspects of photography, this is a lens for you.

Shame about the price though. I do think it is overpriced, but at the same time I can see this lens getting a lot of use and giving me a lot of payback.

In general I'd give it a thumbs up and recommend it to anyone.
