Originally posted by Rondec A slower release schedule for full frame lenses is probably fine once they get the line up filled out, but till they get the basic primes (ultra wide prime, 50 and 85 -- I know there is a 35-ish prime as well, but since we have the FA 31, that one isn't crucial to me) done, they should be cranking out at least three new lenses a year. It really doesn't feel like that is too much to ask for.
They probably won't risk expanding R&D, because after filling the gaps in the lenses line they may have to shrink again and fire staff.
I saw some examples for such behaviour in my former profession. I remember one case, when a big company placed a very big order with one of our competitors for a special model (metrology equipment). They refused to take that order, as it would have either needed big investments in buildings, machinery, and staff, or it would have blocked any normal production for several years. What happened in the end, was that the ordering company just bought the manufacturer, and took the risk themselves.
Think also about Boeing and Airbus: the media proudly announce if one of them gathered much more orders than the other, which is absolutely meaningless. Production of both companies is booked out for more than a decade already. But none of them risks strongly expanding production - what to do if orders decrease a lot in the future?
EDIT:
We just see the same problem with railways. None of the manufacturers (European or Canadian) can deliver on time. 1-2 years late must now be expected. The manufacturers just pay for the delay, probably had it in the calculation of their offerings anyway. Do they expand their production lines? No, they presently all are shrinking them (and some of them are booked out for many years, too).
