Yesterday I received the Pentax Magnifier FB that I ordered from B&H. It fits the *ist DS perfectly: slides over the eyepiece after removing the standard rubber protection, flips up and out of the way for normal viewing, then clicks down into place to allow precision manual focusing. The ocular is rubber coated and turns for focusing.
I think it is diopter adjustment, not sure it's the same as focusing.
Yes, it is a diopter adjustment ... that allows you to focus the magnifier for the viewfinder screen per your eye's needs. There really isn't any difference other than how you express that.
... Interesting. Last week I got hold of Magnifier M. I agree it is a good
fit on the eyepiece and that it's a nice accessory, but found it
awkward to use, because the ocular is small enough to, err, hurt my
eye. I guess tripod is more or less compulsory with this.
I don't have any experience with the Magnifier M or how it is different from the Magnifier FB.
The FB model has a large rubber surround on the ocular so it is about the same diameter as the standard eyepiece, no more likely to hurt your eye. As I said, it flips up and nearly completely out of the way when you want access to the standard eyepiece, would be easy to keep on the camera most of the time regardless of whether you were using a tripod or not.
