Playing with extension tubes

    Got some extension tubes mostly 'cause I want to close focus (closer than 1 meter) with my Nikon Series E 100mm F2.8 ... gonna be fun.

    Tubes are kind of wobbly. The lens locking mechanism is very hard to operate. About the quality I expect for $20.

    I've got (or should I say, had) the same set. The little lens release pin broke off mine after about of month of pretty light use, so be gentle and don't expect much.

    For what it's worth, I spent the better part of a day playing around with cheap macro options for my Minolta lenses, including extension tubes, reverse adapters, and coupling rings—and for the most part, the latter two options seemed to produce better results than the extension tubes. It's possible that this was due to my particular choice of extension amount vs. focal length, or some other factor, but I definitely found those shots to have some issues such as white haze in the center of the image, low contrast, and so on. If not for my recent purchase of a dedicated macro lens, I'd probably still be reaching more for the reverse lens options than the tubes. But definitely fun (and affordable) to experiment with all of these options!

    I have one and a Teleplus/Vivitar 2x focusing macro extension. The macro extension is much easier to focus and use.
    I mount the OM 50mm and get 1:1 macro.

    I have other lenses I plan to use that cannot fit a 52mm thread - extension tubes work for way more lenses! My 85mm f1.8 has 58mm threads ... not to mention too many years of seeing too many crappy close-up lenses have soured me on them. My glass is good so why stick even more glass in front of it?!

    I bought a cheap set of extension tubes for my OM lenses but never had much luck. Didn't seem to want to lock-in properly.

    I have enjoyed using a reversal lens adapter to mount my OM 28mm 3.5 backwards for crude macro photography. It gets you quite close..

    IMHO extension tubes have advantages: no glass, multiple length combinations... they are cheaper than $20 too.

    Why not get some native micro 4/3 auto extension tubes? I bought these ones (from another seller in Hong Kong, but these are even in the US so they'll arrive quicker - I've bought from this seller just recently actually and they shipped quick) for about $30, they are just over $25 now - there are already a few threads discussing them, but in a nutshell they work great, though AF is kind of useless at such close focus!

    No need to spend $179 for the Kenko pair when you can give these a try.

    If those ever give out, give the K-ring set or M2 tube a try. Solid and cheap.
    I use them with a 100E, 50 1.8, and 55 3.5.

    Very interesting.
    What lenses do you use them on?

    My wife enjoyed them with the panasonic 45-150 and got some good results - from some other threads here on the forum it sounds like they pair very well with the oly 45mm as well. I tried them with the 20mm and they worked but focus was extremely close, almost touching the front element so not terribly practical. For the cost they are totally worth giving a go I'd say. I'd post some examples but don't have any uploaded online at the moment!

    If you want more info there are several threads discussing these types of tubes (or the kenko ones - they are essentially the same, both AF and they are the same lengths) on the forum already if you're willing to do a search!

    That is rediculous for the cost of the Kenko tubes! They've really gone up over the past couple of years. As long as I get auto tubes, I'm happy.
