I wish the Pentax 645 had a low battery indicator.

I dearly love my Pentax 645 camera. That camera feels solid and takes great pictures for me. Unfortunately, it lacks a low battery indicator.I took it with me on my fall trip to WV and took two rolls of shots with it. Sure that I got awesome shots, I proudly opened it up to get the film out of the back when I got home after the trip.  

After I got the film developed (I scan the film myself on my Epson v500 at home because my local lab no longer carries a mask to print directly) I immediately saw what is depicted in the image above. The motor didn't pull the film taut and flat and it didn't advance the whole frame between shots.  

My mistake here was that I wasn't paying a lot of attention to  it before I left. The 6 AA batteries the camera takes should of been replaced before I left to take pictures. I don't think it is likely I will make the same mistake again. Battery sales will increase at my local store as a result.
