Originally posted by Tesla I think the only problem may be getting SR to work with FF?
IIRC the challenge of SR'ing FF was discussed a while back - at least once ... the points were something like:
- battery capacity/drain from the larger mass of the sensor
- accelerations / responsiveness required
- the total range of motion of the sensor, size of image circle
- mechanical wear on the flex print connector cable (due to larger motions)
I don't recollect any of these being discussed as showstoppers - maybe the battery, if they stick with the same one?
I know it goes against the 'We are Pentax - So it must be tiny!' mantra / rut they are stuck in, but you wouldn't hear a peep out of me if they had two battery slots in a bigger body.
On second thought, I always buy the grip anyway, since they are too tiny without, I don't think I'd care; I always have two battery slots...
Maybe the mass of the sensor is problematic. If it were truly an easy to solve engineering challenge then the 645Z would have had SR... or maybe not, maybe they just wanted to sell really expensive SR lenses and it was a marketing decision that if a customer can afford the body, then they can afford the lenses, and it makes the body more reliable / 'affordable'.
I know I've had (or still have...) an issue with the sensor in my K-5 being slightly tilted. It went in for service but came back the same. I gave up and turned on horizon levelling. Maybe twist is harder to keep nulled with a bigger sensor.
