IQ lens upgrade

I have been having some issues with IQ on a 50mm 2.5 macro (which I part exchanged a 50mm 1.8 for) and a 18-200 canon lens

having now had Canon and one of there repair outlets review the images, I'm told thats the quality expected of those lenses.

I have a 60D body so 1.6 crop factor

so if I wanted to change the 18-200 it has been suggested to get the following
I have the opportunity to get a

Canon EF-S 17-85mm f/4-5.6 IS USM - used @ £249 (£370 new
Canon EF 70-300mm f/4-5.6 IS USM Lens - new@ £449 - plus cash back offer

I wondered if the difference would be significant or if the solution is L lens

I dont have any particular subject I take , just a general photographer and I used to take the camera around with me all the time
I had an EOS5 and kit lens and also did a bit of wedding photography and portraits - but dont intend doing much of that now

I then got feed up carrying all the kit around and changed to the canon PRO1 when it first came out , but although i thought the quality was OK the limitations where quite high especially on shutter lag and low light usage - so action was difficult to capture

So i stopped taking pictures - well now i'm interested again and love the 60D body - does everything I think i would need - (except eye controlledfocus)

so a good general purpose kit

would those lenses make a huge difference

I will have a look in the lens archive

just wondered on peoples suggetions

as i dont want to spend another £400-500 and not really see the difference

I have been told the change to those lens would be the USM and not really a great image quality change
and so a
17-40 L F4 non IS
70-200L F4 non IS
would be my entry point @ £620 + £530 (£1150)

I am not sure if the 15-85 fits ur budget but its one awesome lens for general purposes

My personal opinion is that you would be better of buying the Canon 70-200 f4 L which is in a similar price range if you were thinking about a new telephoto...

Thanks for the very quick replies
i edited the post

Yep - just been told that by a store too

and that the glass change is not significant in the lenses i mentioned

Canon EF-S 15-85mm f3.5-5.6 IS USM Lens @£600

do you think would be better then a 17-40L ?

i will have to go look at the archive

well that just saved me going off to the shop today and swapping for those two lenses and shelling out another £400/500 quid

I'm used to not having IS - but think it could be a great advantage especially with F4 lenses, but then the quality of the increased ISO on the 60D is brilliant - so i could get a couple of stops by using iso 400 I guess

thanks for the quick reply

What are the IQ issues you have been battling? The 18-200 being such a wide range lens is not the best lens in the camera bag but it's far from a complete looser as well. Can you post some sample images which show the IQ issues? Maybe there is something else going on and a lens upgrade will not solve the problem.

Thanks gjl711 -18-200 and the 50 2.5 I was told was as good as a 1.8 (which i part exchanged) but also had half life size macro

Also been looking at the L series and suggestions are for a 24-105L which the shop has

and then I have converted the full raw images cr2 files to DNG and hosted here

been looking at the 24-105L lens as maybe a solution for me
off to the archive here to see

For reference, there have been no problems from this corner with the Canon 18-200mm IS lens, used with a 60D for these images:

well interesting I went into the store today and took loads of images with a few lens on different bodies

thought I would play a game of guess the lens here

The Canon 15-85 IS is a spectacular and incredibly sharp lens. It is on my 60D for about 85% of my shots. Not only is it very sharp, but the IS is state-of-the-art. Many of us highly recommend it.

i'll be the first to ask...do you have filters on your lenses?

yes, but only recently, not for all the shots , a Hoya UK PRO
i meant to also take that off today - and forgot - as mainly as I expected to be buying the 24-105L lens

Since it's on your options list, I'll comment a little on the 17-85.
The lens is versatile but it's fragile and produces a lot of chromatic aberation. It's usually possible to correct this in pp but it's work that you may not want to do. In fairness, I've shot some saleable images with this lens but I have moved on.

The 15-85 is a better alternative all around, as would be the 17-55/2.8 or the Sigma 17-50/2.8. Sadly, each of these is considerably more expensive.

mmm £800 and £490
v
24-105L @ £800
and did not get the sharpness in the L lens i was looking for today - having taken about 40 images on it
