Which wide angle lense for my 300D I use at the moment the 18-55mm lense that came with my kit for lanscape and wide angle shots. Although this lense is acceptable for small prints stopped down at around 25mm for lanscapes I find that the colour and contrast is poor and the field of veiw too narrow. I find myself at a bit of a loss of what lense to buy to replace it. I was looking at; Canon EF 17-40mm f4.0 L USM, Tamrons AF 11-18mm f4.5 - 5.6 Di II LD Tamrons AF 17-35mm f2.8 - 4 Di Sigma's 12 - 24 mm F4.5-5.6 EX DG HSM sigma's 15-30mm F3.5-4.5 EX DG I am unsure as to how the minimum focal lenght effects how wide the field of view is,if at all as tamrons 11-18mm has a field of view (103 degrees) less than the 17-35mm(104 degrees) which is confusing. This is important to me as I want to shoot landscapes with a lot of forground detail. I have read numerous reviews on all these lenses and have the option of a cheap canon 17-40mm but am unsure if this will be wide enough if so should I get the Tamron 11-18mm. I also would like to be able to use the Cokin filter A series system with my lense of choice. Hope someone out there can help me make the right choice.

The angle of view given for the Tamron 17-35 f/2.8-4 Di (104°) is when used on a 35mm film camera. It gives a narrower angle of view of 77.5° when used on a camera with a smaller sensor, like your Canon 300D. Similar for the EF 17-40 f/4L, it is not significantly wider than your EF-S 18-55. To get wider view, you need shorter than 18mm focal length. The Sigma 12-24 f/4.5-5.6 and 15-30 f/3.5-4.5 zooms are also usable on both film and digital DSLRs. On film cameras 12mm gives 122° view, 15mm gives 111°. On the APS-C sized sensor of the 300 D, these lenses give 97° and 84.5° views, respectively. The Tamron 11-18 f/4.5-5.6 Di II is usable only on the smaller sensored DLSRs, so it will give you the stated 103° view with your 300D. Similar for the Canon EF-S 10-22 f/3.5-4.5 which can only be used on the 300D, 20D, and 350D. At 10mm it gives a 107° view on those cameras.

Thanks for taking the time to answer my question Jon, appreciate it. I was edging towards the digital dedicated Tamron and it appears that is going to be the best choice. I Would of course like the canon EF-S 10-22 but the price of the Tamron is just too attractive in comparison.
