Roll film 120 and 220 Is there any difference in quality between roll films of 120 and 220 format. it seems the 220 film is thinner?

No, there is no quality difference. The paper backing follows the 120 film the whole length, but on 220 film the paper is only used as a leader and trailer, so you get twice the film with 220 on the same size spool. Since 120 will be thicker because of the paper backing, make sure you are using the correct pressure plate, film insert, or whatever technique your camera manufacturer uses for 220 film to make up the different thickness.

Stan is right. Other than that I have heard complaints that 220 tends to not lay as flat as the 120 does. Consequently, you get images that can be less sharp at the edges. I used to shoot quite a bit of 220 and never really noticed this happening with my gear though.

Thank you all. In fact I recently acquired a 220 filmholder for my Pentax 645 at a sale and was surprised to see it had practically the same margin for the film as had the 120 filmholder.

Dominick- Did you say Pentax 645? I see Shari B. (currently question 16 under new questions) is looking for a Pentax 645 manual. Can you hook her up?

Stan, I could not find Shari's question. At first, I misunderstood and thought she was looking for a 645 camera, manual version (as the new version is auto-focus). If she is looking for an instructions' manual, I have one, but it does not say all that much. The Pentax importer should be able to provide one.

Dominick- Copy and paste this link and see if it takes you to her question. She says she bought the camera used, and you may be able to help her with a manual, questions she may have, etc. http://www.betterphoto.com/forms/qnaDetail.php?threadID=5532&catID=100

As Jeff mentions I have also read remarks about 220 not laying as flat as 120, but this is very dependent on specific camera design; in particular design of the film insert, pressure plate and rails around the film gate. Most of the remarks about medium format film I've read center around older equipment with worn/weak pressure plate springs, and IIRC this particular issue is not exclusively 220 but about specific camera systems (I do not remember which one[s]). I've read even more discussion about large format sheet film and properly maintaining its flatness in sheet film holders. Personally, I've never encountered anything that would hint at a film flatness issue with my medium format camera system; 120 or 220. -- John
