Hello and sorry if I reply now (university esams took all of my time), but I've read everything you wrote and I would thank you for your help.
Thank you for the developing tips Revdocjim, but I've a Paterson and considering I'm new in digital developing, I would like to start with this instead of steel reels. (and I've to search on youtube to understand where the negative was in the 120 film
)
I was looking right now for a 645n in great working condition, but I wasn't 100% sure on it. I really don't know if it is only the addiction to buy something new (67 or 645) or my deside to have big 6x7 negatives.
Looking on Flickr, I've found many P67 users with great images in their portfolio and reading on the web, the P67 was described as one of the best medium format camera. Maybe this pushed me to think I wanted the 67.
At this point I will search for Pentax 645 images in order to have an idea of what we are talking about. In fact I would like to ask you: but the difference in negative images is really big? (ok, sorry for the stupid question, I'm able to make the comparison between 6cm and 4,5cm, but what I would like to know is if there is a real difference among them in term of image quality).
For the point you have underline, the focus indicator is an important help. And the fact that there is AF, although AF lenses are expensive, would be a nice thing.
Thank you in advance for your reply!
