Testing enlarger lens coverage

When buying enlarger lenses, it is important not only to choose a lens of the right focal length to give the required magnification, but also sufficient coverage to cover the negative without vignetting. The rule of thumb with enlarger lenses is: Focal length Typical coverage 50mm 35mm 75-80mm 6×6 100-110mm 6×9 150mm 5×4″ I decided to […]

Sontronics customer care

My most recent microphone purchase was a pair of Sontronics STC-1 small condenser microphones, primarily as an upgrade for some less expensive microphones I already owned. I did my homework before buying, and ultimately decided on the STC-1 over other brands based on the technical data, although the lifetime warranty was a nice touch too. Now, […]

So I asked laser dude to cut some more pinholes in other sizes, and now I have 0.2mm, 0.3mm, 0.4mm and 0.5mm pinholes, all mounted in 80mm […]

Testing a zoom lens

When I bought my 450D I started out with the standard 18-55mm lens, and added a 70-300mm to cover most of the usual range of focal lengths. But when I’m on lunchtime photowalks I don’t want to carry two lenses, nor repeatedly change between them. I often miss shots that need a longer focal length […]
