Yesterday I published a comparison of the actual depth of field (DOF) observed with a Fuji 80 mm f/1.7 GF lens on a GFX 100S at f/2. If you haven’t read that, this post won’t make much sense, and I encourage you to at least skim it. In this post, I’m going to look at… [Read More]
Are DOF calculators useful? — part 1
In this article, there is the following statement: How precise are tables and depth of field calculators? Usually most tables pretend to have a precision that is neither available nor sensible in reality. That is partly because the values calculated in the tables are based on the arbitrary specification of a limit value (acceptable circle… [Read More]

FF and MF DOF compared visually
A couple of days ago I posted visual examples of what various circle of confusion diameters (hereafter called CoCs) looked like at somewhat greater than 100% magnification with the 80 mm f/1.7 Fuji GF lens on the GFX 100S. That was in response to repeated discussion on some fora saying that the DOF calculators don’t… [Read More]
DOF calculators and pixel peeking, 80/1.7 on GFX 100S
Ever since the GFX cameras first shipped, there has been a vocal minority claiming that DOF calculators don’t work with them, and that they have far less DOF that the calculators say. I have steadfastly maintained that thinking is wrong, and results from misuse of the DOF calculators, specifically picking an inappropriate circle of confusion… [Read More]
