The lone black-and-white was shot at f11 (and I really wish that Meike/7artisans/whoever made a 16, because that building thunderstorm would have been a lot more dramatic with a wider lens.) But these pictures aren't art, they're to see if the silly thing works. You'll note the hotspot in color from f16 to f8, but it's all or almost all gone by f5.6 and the lens is good at apertures wider than that. In that the camera is going soon to Kolari to get its 720nm filter exchanged for a 590, and in that I'm about to order a 49mm 850nm filter, I'll know those things in a few weeks.īut here's what we have now. This is shooting 720nm I do not know how it will do 590 or 850. Some lenses have what is called a hotspot. Unfortunately not every lens can be used for infrared photography.
I’ll also show you the final processed result. The short version: it's just fine in infrared color up to f5.6, and in black-and-white up to f8 and, depending on the subject, f11. In the following 4 pictures you can see how infrared photography looks like compared to normal light. The answer is not perfectly but well enough to be entirely usable.
The Meike 25mm f1.8 arrived about an hour ago, and the first thing was to test it to see how well it did infrared photography. Takumar was carried over to lenses that fit the 35mm M42 (1957-1973) cameras and went through a series of iterations as build quality and coatings were developed with names such as Super-Takumar, Super-Multi-Coated Takumar, and SMC Takumar (with open-metering capability).
