Hehe I can't get rip of my NEX3, I cracked the back LCD screen. A cautionary tale, you guys may want to consider a thick glass protector. Like the one I have now.
As far as Sony goes, I don't believe Sony needs lens designer. They had gotten lot of them from Minolta. I believe its a marketing problem.
There are at least 3 different markets thats asking 3 different types of lens. First its the entry level, first time SLR/mirrorless buyers who want convenience high ratio zoom, cost efficient lens. Secondly you have business shooters who need expensive, imposing lens of the highest quality because their clients pay for the best stuff. Lastly the one in the middle are the enthusiast shooters who want compact, high quality lens. They mostly want primes because they don't need to get the job done fast.
There may be more niches but I point out the 3 main ones to make my point. These three markets really have different priorities, and different priories encourage different lens designs. Some brands and mounts cater to all three market. Pentax used to skip the pro market and only concentrate on the entry and enthusiast markets. At one time they had more complete lineup of APSC lens than anybody else.
Fuji's X system, as far as I can tell, completely ignore the first two markets and only design lens for the enthusiast market. And this happen to be my market. Sony's NEX system, is still trying to design lens for all three markets. See this is a market approach problem, Olympus can't help them.
