Twin Lens Reverse Macro... problem

[joe_casey5]

<p>I bought a coupler to connect some of 49mm manual lenses together (reversed) to make a macro setup. The only problem is, when I did it, neither lens will focus and give me ANY image whatsoever. I'm using a Pentax 50mm SMC lens as the prime (facing front) with a Zeiss Jena 35mm prime facing in (reversed). Any ideas as to what I'm doing wrong?</p>

I don't know your exact setup but it is possible that you can only focus in a very narrow range and very close to the lens.

Have you checked focus at a subject distance of centimeters from the lens?

<p>I think you need both lenses set at infinity, and then bring the rear of the 35mm as close to the subject as the film or sensor normally sits from the rear of the lens. Focusing is by moving the camera. That's how I recall it from last time I tried!</p>

<p>Yes, it's likely you'll need to be far, far closer to your subject than you think. </p>

<p>Haven't done this myself but recall reading that you'd want the rear element of the wider angle lens facing the subject.</p>

<p>This kind of set-up is meant to be used with a focusing rail on a tripod.</p>
