Originally posted by JohnBee Sony has a history of abandoning products in the pursuit of better technology. The problem wit hthis however is where camera owners often times end-up investing such large sums of money in their kits that they will avoid staying companies who do this in favor of those with long product stability....
I'm not sure how it could be otherwise. Canon has moved to more modern mounts as well. How could any company stay with a product that is no longer profitable. One could debate at which point of profitability a camera company can/should abandon a mount, but ultimately profitability determines what survives.
Pentax has stayed with the K-mount obviously. How has that worked for them? I don't see hordes of customers buying Pentax because of their loyalty to the K-mount. Tamron and Sigma has reduced their support of the K-mount - altho that will may change when the Pentax FF is produced. In the last 6 months in my photography club, 3 new Nikon FF have been purchase, 3 new Sony FF have been purchased and 2 Fuji's and a Panasonic or 2. No Canons that i have heard of. Sony has made all the sensors for the FF cameras i think.
