Haven’t done flashlight reviews, nor photographs on flashlights.
You can although see my writing style and find snapshots i made with my iphone in Here (my first build) (yes there are some badly focussed pics too, but that didn’t matter, it showed the essence) and over here at cpf , and some more pics of baked flashlight later on. All taken with iPhone.
Most pictures i post on forums, are made with my iphone, for a (photo)review of course i would use my canon in the studio (or take it to my workbench)
