eBay is as good as any and usually has far more choice at cheaper prices, but all sell the rubbish along with the great. That applies to all those so far listed too. It really is a buyer beware situation, it helps if you know what your buying.

If you tell us the specific lens your after then we may be able to steer you to a decent one. Where you are in the World would help too.

Be very careful of utilising DigitalRev. We offered a Canon digital camera from them till now Christmas. On in basic terms the 2d time we used the factor the shutter blades went haywire. We tried in ineffective to seek for the help of DigitalRev yet all we won became into excuse after excuse. Canon uk guarantee is invalid in case you purchase from those people as we've found out. All in all that's greater appropriate identifying to purchase your product from a uk broking whether you ought to pay some greater advantageous kilos. DigitalRev are to not be relied on.

B&H Photo is one of the largest and most reliable.
