Bellows II

Does the M42 bellows II have two geared rails, one that extends the bellows and one that moves the camera body?
This is the unit I am asking about.

No, the lens mount is on a geared rail with knurled knob on left and locking knob on the right. The camera mount is adjustable and locks with a lever on the right side. But it is not on a geared rail.

The bellows front where the lens is attached is the part that moves with a dial. The rear camera mount is lever locked and usually left alone.

Here is a copy of the K series (Bellows III) manual, which is similar.

gofour3, excellent, thank you!

From a bit of playing with extension tubes I decided that using a tripod outside would be no joy, so basically trying to determine if a Bellows II or any other for that matter, allows for gross focus adjustment by moving the camera independent of the tripod. A geared rail would be nice.

The Pentax macro focus rail works well, a bit hard to find though.

+1 on the macro focus rail. The Pentax one is built like a tank. Really makes you appreciate the way things used to be made. Lots of cheaper ones on ebay that will work fine though. Highly recommended if you are using a tripod.

Thank You! Just shows what a serious case of LBA and a lot of time watching ebay, estate sales and thrift shops can produce. All I'm missing is the S-M-C 500mm f/4.5 but they are too expensive for me.

I use the Pentax Auto Bellows M42 - it has a built in focus rail you are interested in.

Yes, that is exactly it! Thanks, now to find one at a reasonable price. I enjoyed your blog.

Over the weekend I watched a Bellows 2 on ebay, seller with 100% feedback and a very nice unit. My internet took a crap when I bid and the bid never got placed. The Bellows 2 sold for $6.00 ... aaaaaaarrrrrrrrrrrrrrgggggggggggggg

I am glad you enjoyed the blog. I have seen similiar models with a focus rail by Olympus and Canon. But I think it is easiest to mount lenses if you start with M42. I am guessing Nikon and other's made them with focus rails as well.

Well I am the proud owner of a Pentax Auto Bellows M.
Special thanks to a forum member who actually made it possible and who shall remain nameless unless they choose to come forward.

That takes the sting out of the $6.00 Bellows II, these are better.
