Well, an "old" Nikon! But its a NIKON! Model is AF N600?! Bought it for the lens which is a Nikon AF Nikon 35 - 70 f/3.3 - f/4.5.
Will reverse it on an Olympus E-620. Lens is in good shape, no dings, scratches. Zoom, f-stops and focus works fine.
Question, when attached to the E-620 for macro work, how do I figure magnification factor at various zooms?
(Hope I have not violated any rules, laws by attaching a Nikon lens to an Olympus! :)

Second - the best way to know your magnification is to photograph a metric ruler, and compare capture to measured size of camera sensor.

So are there any combinations of reversing two lenses that do work? Two primes? A prime and a zoom? Half a zoom, two thirds prime and a 1.4 TC?!? :shock: First - do not expect good results when you reverse-mount a zoom lens onto another zoom lens.

I've seen guys do it but my efforts have failed...

Not mounting to a zoom, directly to camera. Thanks for suggestions on using a ruler.
Captured some quick shots and look good so far. Will try more tomorrow.

My error. Straight reverse is easier, still requiring a special camera mount-to-male-thread, to be able to attach a lens using the female filter threads.Not mounting to a zoom, directly to camera.
Again, do not expect decent results, as all zoom lenses, and all standard prime lenses, have a curved arc (field) of focus for normal use, and reversing causes the lens to project a curved field to the sensor. Large apertures can cause corners to be OoF.

Two primes are the preferred combination for stacking lenses. So are there any combinations of reversing two lenses that do work?

What camera/equipment do you use? = "Im currently using a Pentax K-x with either a vintage 28mm or 50mm prime reversed to the end of extension tubes. In the rare chance that I have a highly cooperative subject, I may bust out my macro bellows for some really high magnification shots."

Indeed it does. I was just razzing you over the camera system (Nikon). I love picking up old glass, some real value if one doesn't mind manual focus and aperture.Well, for ten bucks, seems worth while. Better than a sharp stick in the eye!

Ok, I get it. Now I see the light! Pick on the old "guy" day! Wait until I show the "stunning" images!
