Kamisafe Fotofans Macro Focus Distance Adjuster
This is a quick look at the Fotofans micro focus adjuster by Kamisafe. I don't exactly own a macro lens, but this does help if trying to use an ultra shallow depth of field, or if doing macro photography.
Ultimately, while this is a cool tool, and it does serve its purpose, I don't think I'll use it that much. You can still get very good adjustment of focus out of most lenses already. I think the most useful part of this is getting close to your minimum focus distance with your tripod, then using this to dial it right up to the minimum to get as close as possible.
Would I buy it again? Probably not. It's a quality tool, I just don't see myself using it much.
