Actually, I believe that the price will not be that bad. It will have to be lower than their current models in that focal length range if the apertures are what they plan. The only one of these that I know of is the 300mm and it costs about 35% of their traditional 300mm lens.

This has potential to be very good for the consumer.

It would be good to know the time frame when these might be released onto the market, I might persevere with my Tamron G1 a bit longer and see what happens.
