A while back I wrote a short article comparing wide angle lenses on various formats. This is a small update to include large format (4×5″), which I have recently bought into to overcome problems with super-wide lenses on 6×9 (or lack thereof) This diagram shows various common film formats, ranging from 4×5″ (large format view […]Read more "Wide angle lenses – now with 4×5″"
Since I embarked upon my Somerset Towers project, I’ve visited over a dozen churches across the country to photograph them with my Horseman 980 view camera. It’s barely made a scratch in the project, but I have learnt a lot already. View cameras are appropriate for architectural photography because they allow the photographer to capture […]Read more "Wide angle lenses"
I know everyone who has several lenses for their camera does a comparison, but that isn’t going to stop me from having a go too. Here is the same view, seen through every compatible lens in my collection. I decided to use my Canon FD manual focus gear as I have most lenses for that, […]Read more "A comparison of focal lengths"
On photography forums I see a lot of confusion about what is meant by prime lenses, zoom lenses, and telephoto lenses in particular. A zoom lens is able to change its focal length, i.e. to zoom in and out. This does not necessarily mean that it is a telephoto lens. A prime lens has a […]Read more "Prime, zoom, telephoto or wide angle lens?"
These days, camera lenses are high-tech pieces of kit. Each manufacturer uses many abbreviations and acronyms to refer to the various technologies and it can get confusing to compare lenses – especially when different manufacturers use different names to refer to the same technology. You can look up the abbreviations on each manufacturer’s website (see […]Read more "Lens designations"
I’ve probably discussed before the way that different size “sensors” (or pieces of film) need different focal length lenses to achieve the same angle of view. For instance, it is well known that a 50mm lens on an APS-C crop-sensor DSLR behaves a bit like a 75mm lens on a 35mm full-frame camera. I’ve extended […]Read more "Angle of view on various formats"
After making some pinholes recently, I tested them with my DSLR. It has a tiny sensor and it’s not even the camera I intended to use the pinholes with. So naturally I’ve now tested them with my Horseman 980 view camera, which has a sensor area sixteen times greater than a crop-sensor DSLR. I was […]Read more "Second pinhole test"
