You mean like these? Aperture: http://www.digicamguides.com/learn/aperture-examples.html Shutter Speed: http://www.digicamguides.com/learn/shutter-speed-examples.html ISO: http://www.digicamguides.com/learn/iso-examples.html

If by colour fringing you mean chromatic aberration (CA), then yes, the 17-85 is not good for that! You've four options: 1) Avoid shots at 17-20mm. It seems much worse at those focal lengths. 2) Shoot in RAW and process in DPP. The auto-remove tool for CA works very well, IMHO...

If you want autofocus and really wide angle, there's nothing else to the best of my knowledge. I'm afraid that the Sigma already is the poor man's edition, being substantially less than the Canon 10-22. If you're OK with manual focus, then you might want to look at the Samyang/Zentiar...

Polarizing filters lose you some light, typically 1-2 stops. With a slow-ish lens like the 55-250 and a sport requiring high-ish shutter speeds like rallying, you might not find them too practical. The light loss will also likely slow down the autofocus, and the fact that the front element...

I'm very happy with the second-hand 420EX that I use. They're currently going for around £70-£80 on E-bay. The 430EX will stretch your budget, but you might get lucky. The 430EX apparently recycles more quickly, has a better control panel (you have to set pretty much all the 420 functions...

According to http://support-asia.canon-asia.com/contents/ASIA/EN/8200740600.html Err 20 is "Malfunctions related to the mechanical mechanism have been detected." (Edit - posted at around the same time as you - sorry - you already know it's mechanical! If it's still under guarantee, I'd be...

Not PSE - but a freeware program that I find useful for this type of image: ShiftN: http://www.shiftn.de/

Not sure what your definition of "cool" is, but Whitstable has a bit of character, IMHO.

I'm looking to get hoods for my Canon 17-85 and 100-300 lenses. E-bay seems awash with cheap, typically Chinese copies. Are any of these any good? Or should I splash out the seeming;y ridiculous sums that Canon wants? Thanks for any recommendations.

Your lens / camera combinations will be out-of-spec for autofocus with either the 1.4 or 2x converters. Canon's consumer range of cameras only autofocus at up to f/5.6. The 1-Series cameras will autofocus at f/8. HOWEVER...many of the third-party (i.e. not Canon) teleconverters do not...

You are misunderstanding something. The f/3.5-5.6 rating of your lens is telling you the maximum (i.e. largest) aperture that the lens offers. It varies according to the focal length. At 28mm it will be f/3.5 and at 135mm it will be f/5.6. The largest available aperture lets in the most...

I agree, very unlikely indeed that Photobucket is offering malware banners. However, the OP said "I hosted some pics on photobucket on another site", which I took to mean that the malware banner was on another site, not Photobucket. Perhaps the OP could clarify?

PC Antispyware 2010 is indeed a nasty piece of software that you do not want to install on your machine. If you don't believe me, just ask Google... http://www.google.co.uk/#hl=en&source=hp&q=PC+Antispyware+2010&btnG=Google+Search&meta=&fp=f8018b3e94e32b3b It sounds like the hosting...

Handle both. IMHO, the main difference is in how the cameras feel and operate. Depending upon the size of your hands, how well you "click" with the user interface, how heavy you like your camera etc., you should soon know which is right for you. If after handling both you still can't...
