The Diana 3 5mm Back+ is a great investment for the Diana F+ as it makes your camera more cost-effective, and it means that you don't have to go through so many rolls of film! I received one for my birthday in June and I really love it, especially the sprocket hole option. The only downside is the adjustments that need to be made to the framing of the photo.
These are necessary because 35 mm is a different format than the usual 120 film, so not all of what you see through the viewfinder will end up in your photo. Of course, I always forget to keep the subject to the middle of the frame, and have had many disastrous photos where I forgot to adjust!
To avoid this, I came up with a very simple solution. Follow the guide here.
Use electrical tape to cover the top and bottom of the viewfinder. Masking tape or duct tape works just as effectively. I covered approximately 6mm on each side and this seemed to work well.
Now, what you see through the viewfinder is what you will get on your film. It's very easy to remove and replace if you are switching between formats.
Get shooting, it's as simple as that!
While most of my shots are now lined up correctly -- thanks to the fact that I no longer have to trust my rubbish memory -- there are a few which are only saved by the fact that I had the sprockets developed!
To counter this I would lower the top piece of tape slightly. Overall though, this has definitely added to my enjoyment of the 35mm back, and I was able to take so many photos on my recent holiday. I love the freedom of 36 exposures per roll!
Finally, this is a good step to take even if you yourself have no trouble remembering to adjust your framing. This way, if you lend your camera to a friend, or ask someone else to take a photo, you don't have to try and explain format ratios to them before they click the shutter!
