Fujifilm FinePix IS-1 review
I have used this camera for 6 moths or so, it is the same as
Fujifilm FinePix S9100 (Fujifilmn FinePix S9600) except that the infrared blocking filter has been removed, hence low value for money, why should it cost more for a missing component... You will need to add an external infrared filter for IR images, and an infrared blocking filter for normal color results.
It is straight forward to use and the 2 custom WB settings are very useful. Image quality has more noise the stronger the infrarefd filter usesd , less apparent with a 25a, more apparent with an 87c. This also goes for the "hotspot" in the middle of a frame - a known issue with IR photography with a lens and lens coating not really designed for Infrared use.
The hotspot is aperture sensitive, not appearing so much when a wider aperture is used and a low strength IR filter such as 25. If you shoot with an 87 and stop down expect the hotspot.
It can produce some great infrared pictorial images with certain limitations if you need to avoid the hotspot.
Hotspot in centre of image is the only real problem, it will happen with every IS-1 camera in certain conditions. The photographer needs to open up the lens to make it less with the disadvantage that the image becomes less sharp. Also when using a longer focal length the hotspot can become more noticeable.
