After posting on 35mmc and reading all the articles surrounding the different film holders, finding myself like many drifting towards 120 film, I was drawn to the price and 'one-stop shop' solution the Pixl-latr offered. Honestly, it's 3D printing roots show through with difficulties had getting a truly flat film plane, and similarly the need to get the masks for light creep at the edges, as well as a slightly fiddly way of moving the frames along.
But....
It works! You can do the different formats, with a little tape it will create a flat film plane, and also mask the worst of any light creep- and for such a low entry price compared to other options, plus easy availability and community support, it's worth giving a try- I've found with practice and time, results are improving, and the workflow pace increased. I would suggest anyone who is deciding with DSLR scanning vs. Flat bed reflects on how much time they really want to spend getting it done; DSLR isn't the quickest, especially whilst you learn to get all the pieces in sync, and I've seen just as pleasing results from Epson V-series, which require less hands on time.
Nothing is perfect, and if you are desperate for the best quality and results; send it to a lab like the Wonderlab (please, for the love of everything, make 120 C41 and E6n happen, I know you would do an amazing job- take my money!).
