Canon EF 80-200mm f/4.5-5.6 Lens

This is one of Canon's budget lenses, and has the less robust "plastic" lens mount and only 5 aperture blades. That said, it does a cracking job of being versatile, lightweight, fast focussing and value for money. Sure, there are better lenses - and yes, you pay for that, but for around £65.00 second hand, you get a good workhorse that still produces A3+ prints of more than acceptable quality.
The 52mm filter size is a bit of an issue, as all my filters are 67 or bigger, but at least at that size, they are CHEAP.
There is no Image Stabilisation on these lenses, they are so light it's unlikely you'll ever need it anyway.
This is a pocket-sized lens that you can afford to throw around a bit, unlike some of Canon's L series IS lenses
I bought one recently for £50.00 S/H and took it to RAF Waddington's air show 2008, as my 70-300 was being serviced.
The Vulcan pics are so good, I sold them to friends, enthusiasts and two magazines.
In fact, my earnings from this lens have already outstripped the purchase price. It will be given to my son when the 70-300 comes back, but until then -I'll keep on using it, thanks.
