Some tables on maginifcation here Can google extension tubes for more info, though need to filter out some of the stuff for sale. There was a site that teaches you how to calculate maginication with extension tubes, but I lost it. Maybe the macro gurus at the macro forum can help.Hoky said:Just wondering how close can you go with an extension tube?
How do they work? (As in to aid autofocus)
And how compatible are third party extension tubes?
Please advise noob here.
1) Neither, get a dedicated macro. the sigma/tamron macro offerings are pretty goodHoky said:Thanks to all for the comments. I'm confused if I should get a close up filter or extension tubes.
Although extension tubes will be more economical, since I have lens thread size of 58mm to 77mm... the price of close up are pretty cheap and I don't think i'll fit it to my ultra / wide.
How would you judge image quality, degration and ease of use between the both (ext. tubes & close up filter)
