16-35mm 2.8 or 10-22mm

[dearcharlie]

hey guys atm i have a canon 500d and i really want a very wide angle lense..im torn between the 16-35mm 2.8 and the10-22mm,

the pros for each are: i like the 16-35mm because it can fit on a full frame camera if i get one, one day.. its 2.8 and its L series.. but i heard that when you put this lense on a non full frame camera it acts like a 24-36mm and is not wide at all

: i like the 10-22 because its cheap and i can get it soon and that it is wide which i want. but it wont fit a full frame camera apparently which sucks and isnt L series and doesnt have 2.8

really not sure what to get.. if the 16-35mm does act like a 24mm on the widest then i guess im not interested ATM.. but i do want it because of the 2.8 L..please advice me on the best route i can take i want a wide angle lense..

thank you very much

If you want wide go for the 10-22.
Down the track, if you get a full frame camera, then keep your existing camera/lens as a backup/second camera.

The 10-22 holds good resale value. When you get the full-frame camera, time enough to sell it and get the 16-35L II. Consider the $100-$200 you'll lose on the price selling it used as your rental fee for the lens for the three-to-five years before you can afford a $3k full-frame camera.

Or. Consider the Tokina 11-16 f/2.8.

thanx all for the advice i guess your right,, but is it true that the 16-35.. acts more like 24mm on widest if not on a full frame

because of the cropped sensor in the 500 you need to multiple the quoted focal length by x1.6 on all your lens, so 16mm x 1.6 = 24mm (ish) , and the 10-22mm becomes 16mm at it's widest angle. I use a 10-22mm and a 17-40L, the 10-22mm feels cheaper than the very robust 17-40 but the image quality is excellent.

oh okay thanx.. but why is the 10mm becoming a 16mm.. because isnt it true that this lense doesnt work on a full frame camera such as 5D.. so if not then wouldnt it be 10mm on the 500d.. or they should have just labeled it as 16mm

[RichardTaylor]

The focal length always remains the same - it is part of the lens design. It is the field of view that changes with sensor size change.

The 10-22mm refers to the minimum and maximum focal length of the lens, no matter the type of camera you would use it on. So if you have an APS-C (non full-frame) camera you should always keep in mind the crop factor ( 1.5 or 1.6 ). In your case it is 1.6

Ditto to what the guys above have said, but I also wanted to give you a huge thumbs-up for the 10-22. I have that lens and it is wonderful!

The 10-22 is also sharper than the 16-35, which is terrrrible.
