<p>Thanks you all, I will give it a try and make it work once I've decided on a camera :-)</p>

<p>Thanks Martin, very helpful!<br> I see what you mean: with the circumference being 2πr, and r being 7cm in the case of my drum, half de circumference would be a little over 21 cm, 8 inches in other words.</p>

<p>My dad picked up a Unicolor drum ages ago and now that I want to start dabbling a bit with 5x4 format, developing the negatives myself, I'm trying to figure out what I'm having and what is missing. The drum is 34cm long by 14cm in diameter but the only marking is 'Unicolor'. I know that I'm missing the roller machine and I have seen the mention of 'spacers' in the context of Unicolor drums but I do not know what there are. <br />My first question is: do I have a Unicolor film drum or a Unicolor paper drum? I guess it is a paper drum but that is good for LF negatives.The follow up question is: do I need anything other than a roller machine?</p><div></div>

<p>Hi, I have a Pentax 645NII and picked up an adapter for my Pentax 67 lenses. I was wondering what the "cropping factor" would be for the SMC Pentax 67 lenses when used on the 645. My gut feeling is that it would be something like (6x7) / (6x4.5) = 1.56 but I'm not sure if that is the right way to approach the question. <br> <br> Hans</p>

<p>Hi, I picked up a Komura Telemore 95 2x converter for my Pentax 67II for a few pounds. As this is my first experience with converters, I just wanted to make sure that I understand how to use it correctly: Am I right in understanding that it requires an additional 2 stops when measuring via a handheld light meter? The TTL light meter of the Pentax 67II will work without correction, am I right?</p> <p>Thanks!</p>
