They don’t want to cannibalize the other product markets. Canon for example was caught up with the video features that they added to the 5d back in the day. it sparked a video revolution, but destroyed their camcorder sector. same thing again when they released “cinema” specd cameras, that really just had different firmware than the photography cameras, but priced much higher.
- LorenPechtel 5y agoCinema requires different lenses. A standard camera lens will not remain in focus while zooming. Cinema lenses have to--imposing restrictions that cause the lenses to be a lot more expensive. (A cinema lens works fine for still photography, but why pay the price/weight premium?)
- nullc 5y agoParfocalness can be emulated in firmware (by adjusting the focus as the zoom changes). What you probably should have pointed out is the opposite property: keeping the same focal length while changing the focus distance. This can't be emulated in software because camera lenses don't have a motor on the zoom (plus primes don't have a zoom). Some cine lenses do achieve this by moving a zoom-like group (I think all the ARRI master primes do) and not just by being telecentric on the exit side.
