So... Im short on cash at the moment and lookin for a cheap but cheerful lens...

So im looking at this Opteka 650-1300 lens, It has f/8-16 and its manual focus...

But im wondering if this would atuo focus on my D90 because it has built in focusing?

Would it work? Is the high F-mumber bad?

Anyone help? :)

It'll work, but do bear in mind the old saying: you get what you pay for. It will be manual focus only. High f number in this case is not good. 650 at f/8 is going to be a challenge to hand hold already and you'll likely need to use high ISO in anything less than the brightest light. 1300 f/16 - tripod is pretty much essential.
