I bought my canon 40D last year. It came with a 17-85 lens. I am looking at replacing it with a 18-200 lens. there are a few different type. I am not sure what the diff type of lens do, i.e USM and the other type.

Any recommendations? Any ideas?

Canon do one lens in this range and Sigma and Tamron do one or two each. USM is the Canon name for an ultrasonic autofocus motor. Ultrasonic motors can be quieter and faster than the normal sort. Anyway, the Canon lens doesn't USM and I don't know if any of the Sigma or Tamron have their equivalent.

The Canon lens will probably be marginally better, but then it'll be more expensive too. You have to weigh up whether it's worth it for you.

The Canon 18-200 is a (relatively) cheapy EF-S lens, so is unlikely to be be a marked improvement over the kit 17-85.

Depends what improvement you're looking for. If the ability to go to 200mm is what you're looking for, then I'd say it is a definite improvement.

i suppose what i was looking for is a better zoom then the 17-85 but i do not want to compromise on the picture quality. I was hoping to just have one len for ease of use.

Do you lovely folks think maybe i should buy an addition lens then for my needs? maybe something else?

What sort of photography do you enjoy?

If you want to take lots of (motor)sports, then you'd struggle with an 18-200 type lens because they're all very slow.

If your one true passion in life is landscapes, then maybe look at something like a Sigma 10-20.

If you're into portraits, then get a nifty fifty.

If you're really after doing as much as possible with just one lens, then go for a superzoom (I think the latest Tamron one is something like 18-270mm?) but don't expect the best image quality known to man.

okay... i like landscape shots so i think i will be getting a 10-20 lens. Even though my lens is 17-85 is it still worth buying the 10-20?

Also, i want to take pics of flowers close up. The 17-85 is okay but i find i can not get that close.

i am clueless as you can tell. its my first SLR.. i have only had the canon ixus and sony T7 before this...! i love my 40D... wanted to make the most of it!

A 10-20 is too specialised, if you want to be the most flexible (as the 'superzooms' aren't as fast as most lenses) then get a wide angle (18-55 or similar) for landscapes and portraits, then get a cheap 70-300 zoom or thereabouts if you want to do nature, sports or whatever.

Lenses don't lose much value though (especially if you can buy 2nd hand to start with), so could be well worth getting the 18-200 if you're not sure what you want now.

Aha! You start to realise where all your spare cash is going to go from now and forever more! hehe

For whether a 10-20 wide angle is worth it, only you can decide, but in terms of difference, that comes from the percentage difference, so a 10mm difference between 10 and 20mm is halving the field of vision, whereas a 10mm difference between 50 and 60mm is only taking off 20% or so.

To illustrate this, I've just taken the following snaps out of our bedroom window. Apologies to the perfectionists for the wonky horizons and the like! All the shots were taken with the lens up against the (rather dirty paperbag ) window, so are all from exactly the same distance....

10mm


20mm


50mm


60mm


For the close ups of flowers and stuff, you can buy extension tubes to go between your 17-85 and the camera body. You won't get quite the image quality of a dedicated macro lens, but as a starting point, it's a lot cheaper.

HTH.

IMO the 17-85 is distinctly average picture quality already. Its soft wide open, not realy sharp stoped down, slow, has CA and distortion.

Your not going to improve that situation with an 18-200 either.

Do you want mroe focal lengths, if so then do what an SLR is meant to do, use multiple lens's.

Get a 18-50f2.8 (tamron) and canons 55-250IS which is fairly cheap and decent quality.

Take that to it's logical conclusion and you should only use prime lenses. For some people though, the lesser image quality of zooms is worth it for the extra convenience and for some people the image quality of an 18-200 lens is worth it for the convenience.

Yeah sure, I'd be happy with a bag full of primes. My zooms are (and probably most other peoples) pin'd to one end or the other anyhow.

I guess it depends on what you find acceptable, I personaly wouldnt be happy with the quality I would get out of the 17-85 or the 18-200, tho I would consider one as a one lens do it all holiday lens.

Okay so this is what i am thinking... my line up would be ...


Canon EF-S 10-22mm f/3.5-4.5 USM IS (need to buy)
Canon EF-S 17-85mm f/4-5.6 USM IS (my existing lens)
Canon EF-S 55-250mm f/4-5.6 IS (need to buy)

What do you guys think?

When I was looking for a wide angle, the Sigma 10-20 beat the Canon 10-22 in every single test I managed to lay my hands on, and it's around £100 cheaper as well. smile

Looks like a nice collection of things to buy! wink

Depending on how much stretch you need, may be worth considering the Canon 28-135IS?
I bought that for my 40D instead of the 17-85IS and find it brilliant.
I pretty much used it all day at the FoS (beyond the extra stretch of my 70-200F4L!) as it's quite a versatile lens.
Not quite wide enough for decent car shots, but I'd sooner sacrifice IQ than a lens that's soft at either (short or long) extreme! smile

The Canon 10-22 is not and IS lens.

17-85 was designed as a digital version of the 28-135 walkaround lens (equivalent range). Sadly it suffers from cronic barrel distortion which is why I sold mine. Smae of the effects can be fixed in DPP etc with the correct settings from RAW but that's not the point.

I'd personally go with the Sigma 10-20 rather than the Canon, cheaper and better image quality based on trial shots I did at a store open day. If you are useing it for landscape then stop down to at least F8 to loose the CA.

The Canon 70-300 IS may be worth a look as it is well thought of. It's more than the EF-S 55-250 but give a longer range at the long end as a swap for the short end you alrady have covered.

Just remember, the longer the range the greater the compromise you are buying and you get what you pay for.

I think for the time being i will get the Sigma 10-20.

I have 3 options:

1:- sell the 17-85 and buy the 28-135 and also the 100-400

2:- Keep the 17-85 and buy the 55-250

3:- Keep the 17-85 and buy the 70-300

So unsure as with most things in life!

Get yourself and your camera to a decent dealer and do some trial shots and get a feel for the options for balance etc. You have to make the call but all of the options you are considering are good, the biggest factor that will influence your selection is likely to be cash (17-40L, 24-105L, 100-400L or 70-200L?)
