Hi again all.

I am looking at purchasing two new lenses for my 350D. After some great recommendations from people here I have returned once again to seek some more advice.

I have a 17-85 IS lens, a cheap 90-300 and would like to get a 50mm standard (for portraits and candids) and a wide lens to get some great lanscapes.

In wide I am considering the Tokina 12-24 which I can get for $799 Australian ($600US), about $500 Australian cheaper than the Canon 10-22. From what I have read around the net the Tokina is slightly more attractive than the competing Sigma lens, not quite as good as the Canon (but better build quality) but also ony two thirds the price.

In regards to the prime lens the Canon 50mm 1.8 is cheap and that attracts me, but I have read it has more distortion than the f1.4 version. Again though it's significantly cheaper.

Now I haven't been overly inpressed with the sharpness on the Canon 17-85IS, maybe I'm too picky, but I would like something a little sharper if possible, thus the 50mm prime consideration.

So the question is, firstly would people recommend the Tokina over the Sigma (10-20 or 12-24), and would the Canon offer a $500 Australian better (& sharper) result? Secondly, is the price difference in the 50mm 1.4 & 1.8 truly representative of the quality difference?

Budget is an issue but I will spend more only if the $ spend is justified in the result. Which I know is a little subjective. I am only an enthusiest so spending thousands on lenses is not all that appealing.

If anyone has any comments, questions or suggestions please let me know.

Thanks very much.

Dave.

Mmm, well if you haven't been impressed with the sharpness of the 17-85 then you're going to be really really disappointed in the 50mm primes!

Look at the MTF charts:

17-85: http://www.canon.com.hk/en/Consumer/...p;tag_id=10515

50 f1.8:
http://www.canon.com.hk/en/Consumer/...p;tag_id=10103

50 f1.4:
http://www.canon.com.hk/en/Consumer/...p;tag_id=10104

The 17-85 is a pretty sharp lens - can you post some samples of shots you're not happy with? Perhaps we could help.

Optically there's not too much to choose between the two fifties.

But the more expensive one is f1.4 v f1.8, has a USM motor for faster focus, and is made of metal v plastic. So it's easy to see why it's more expensive.

Thanks for the info peripatetic. I had seen the MTF charts before and had no idea what they represented. That helps a lot.

Cheers.
