Photo Forum / Digital Photography / DSLR Cameras / June 2006Pentax *ist DS and fast Pentax A lenses
I have the opportunity to pick up a used Pentax A 400mm/f2.8 ED-IF to use with my *ist DS -- I've used my Promaster 70-300mm 4-5.6 exclusively up to now in wildlife photography, and feel that I need to make a move up to improve my image quality and composition. Other than the manual focus aspect, does anyone have any experience with this combination and/or advice they would like to share? >I have the opportunity to pick up a used Pentax A 400mm/f2.8 ED-IF to use >with my *ist DS -- I've used my Promaster 70-300mm 4-5.6 exclusively up to >now in wildlife photography, and feel that I need to make a move up to >improve my image quality and composition.

I don't have the 400, but I have the A* 300/2.8, which I've used with both film and digital bodies. If you can find one, try and get the 1.7x AF adapter - it works very well with the long glass, and would give you a 680/f4.5 (equivalent field of view, on a *ist-DS, to a 1000mm lens on a 35mm film body). Plus you'd regain auto-focus - a definite benefit with the longer focal lengths, with practically no depth of field. >I have the opportunity to pick up a used Pentax A 400mm/f2.8 ED-IF to use >with my *ist DS -- I've used my Promaster 70-300mm 4-5.6 exclusively up to >now in wildlife photography, and feel that I need to make a move up to >improve my image quality and composition.

Thanks for the feedback, guys ... I'm thinking that I will purchase it and see how it goes without the AF adapter before trying to run one of those down as well. > Thanks for the feedback, guys ...

Approximately $2,000 USD. >> Thanks for the feedback, guys ...

So I am guessing that the new 10MP Pentax is on your list as well. It is certainly on my list. > Approximately $2,000 USD. > [quoted text clipped - 5 lines] >> >>Sounds like a good plan, what sort of money are we talking here? |
