IMHO Ricoh Imaging cannot compete with the D610, nor with the 6D for that matter - those are 4 years old cameras after all (the D610 is a minor update of a 4 years camera). Perhaps in 3-4 years
The D610 initial price was ¥178,199, while the D750's was 204,000 ¥. In the US, the K-1's launch price was slightly less than that of the D610 and 6D. I see several problems with attempting a cheaper camera:
- it might hurt the K-1's sales (possible solution: do it after having the K-1 replacement ready)
- their lens strategy, without a full range of affordable yet OK lenses and a second hand market it might not work
- their user base might be too small, as cheaper cameras usually require higher volumes to be sustainable (solution: use the K-1 and APS-C to increase the user base)
I'm merely guessing here, but a cheaper K-1 might be the K-1 itself in a few years, or a "K-1 lite" using the K-1's technology in a less expensive shell (and accompanied by a new flagship with improved technology). I'm not seeing this happening this year.
