Hello,

I noticed that when taking a picture with the canon IS 18-200mm in 200mm the picture is very blurry..

Can you offer me any other lens solution to get sharp pictures at high zoom (like 200mm)?

Thank you!

The question some will probably ask is "how much do you have to spend?"

You can do some post processing to get around the distortion but no human effort will sharpen the softness with that lens.

Without breaking the bank, you can perhaps look at the Canon and Tamron offerings of the 70-300mm lens.

Can you post a sample picture of what you are talking about?

Also, is your "IS" turned on in the Lens?

At what shutter speed are you taking the photos at?

Hi guys, thanks for your help.

Just to make clear, i didn't buy the Canon 18-200mm yet, i'm thinking about it.

The review i saw here made me do some more thinking about it because of the blurry results in 200mm..

(P.s. - a sample for what i'm talking about you can see in "camera labs" review of the Canon 18-200mm lens here - http://www.cameralabs.com/reviews/Canon ... ages.shtml)

The question is, if there is a lens that would give sharp pictures when fully zoomed out?

thanks!

I think you may have misunderstood the terms.

Image blur is caused when your shutter speed is too slow to compensate for your subject's movement or your own but that's not what Gordon's sample pictures demonstrate. What they're demonstrating is the soft optics of that lens, giving the appearance of a blur.

For your question itself, are you sure you don't mean zoomed in? Zoomed out refers to having the lens at its shortest focal length/widest angle. The 200mm focal length of the 18-200mm is when you're fully zoomed in whereas 18mm is when you're zoomed out.

If you do mean zoomed in, there are several lenses that offer reasonable to pin sharp IQ at a long focal length but as I implied before, your budget will dictate your options.

You can look at 200, 300 or 400mm primes but they cost an unholy amount of money for the average person though rental prices are reasonable, the practical disadvantage of course is their lack of a zoom range.

The Canon 70-200mm L is extremely popular though it's still quite pricey compared to the 70-300mm zooms I mentioned by either Canon or Tamron.

Perfect answer, you got exactly what i was aiming for! I did mean "zoomed in" LOL... THANKS again!
One more thing, does the 70-300mm zooms by Canon or Tamron you mentioned before will give a sharper result then the 18-200mm I was talking about?
Can you tell me where can I see some examples?

Have a look at these two shots I did last year with the Canon 70-300mm (non-L), fully zoomed in at 300mm.

The Tamron 70-300mm is reportedly sharper.

I'm glad you posted those pictures because I have the same camera and I'm waiting for the same lens to come from Amazon. It took me a while to decide on it but it looks like I made a good choice. Can't wait for it to get here.
