### 4/5 — Great app, but…

*2026-01-19*

Love your YouTube videos and this app is pretty useful, but could we get custom focal reducer setting and/or add .8x to list of options? Great for those of us using Mamiya 645 lenses on GFX with Kipon focal reducer. Thank you and I look forward to your next YouTube videos.

### 5/5 — Always saving the day!

*2024-08-08*

From his cinematic reviews, to his god like presets, he has given a quick and efficient way of figuring out conversions fast. I’m not quite there to know the information for a custom entry so I do wish there would be a 6x8 option, as I am a frequent user and buyer of the Fuji GX680 series, but I will manage!
