Extension Tubes - Full Disclosure

[Loupey]

... I noted in this thread that the extension tubes alter the focus location? Whatever, I'm wondering, is there a place for these tubes in my long lens technique, in my setup? Do you think they could help me achieve better focus? I've yet to get sharp images.

Of course, I'm hopping the focus screen, heavy tripod, & ability to manually focus the lens without the hindrance of the infinity click/stop will greatly improve my situation. Yet, maybe some elaboration on extension tube use with long lenses (eg. my setup) could help with the problems I'm experiencing. Could I benefit from there use?

Thanks for any comments-
Bob :thumbsup:

The tubes aren't going to help you as they will not allow your combo to shoot anywhere near "infinity".

You've got some nice equipment. I would bet that you're experiencing a lot of camera shake - even on a tripod that is a lot of focal length to manage (especially without stabilization). Do you have a cable release? Can you post some examples (not in this thread but start another).

Thanks for the reply-

Yes, I do use a cable release, yet I notice I have to be very careful with that, the slightest movement of the wire causes shake.

I need to get my current upgrades together & installed, then take some pics to see where I'm at. Not worth showing anything until I do that much. I'll start a thread then-

Thanks again-

Bob
