Sorry for the ignorant request, but what are the lenses available for this system and their FOV equivalent in 35mm. I'm fairly new to my MF system (Mamiya 645) and I still find it helpful to compare FOV's to 35mm. I'd also appreciate samples and suggestions for which lenses to get. I shoot mostly portraits, food and fashion, as well as some product.
Here is a list of the lenses made for the GX 680
and 35mm equivalent focal length to 35mm when
using the 689 with 6x8 film back
50mm =23mm
65mm =30mm
80mm =37mm
100mm =46mm
115mm =53mm
125mm =57mm
135mm =62mm
150mm =69mm
180mm =82mm
210mm =96mm
250mm =115mm
300mm =137mm
500mm =229mm
100-200mm =46-92 Zoom
With a MF digital back used on the back of a Fuji gx680 the 35mm equivalent needs to be multiplied by about 1.5x
