Originally posted by mecrox I wonder whether people really do buy into camera systems for the glass. Some people do, of course, but does everyone? There may not be enough dedicated buyers of $$ glass to go round for all we know. I'm not sure the big camera system with scores of components and accessories can be relied on as a given in the years ahead, in the way Canon or Nikon have come to typify it. The cost and complication must be enormous. Suppose the market shrinks to the point where such ambitions are unsustainable. The market for cameras could develop or even break up in all sorts of ways. Aristophanes has suggested that Sony are engaging in a spot of vampirism. They know that a lot of their bodies are bought by people using Canonikon FF systems who have a lot of glass already and plan to use it with an adapter, so there is less heat on Sony to flesh out a system quickly. Buying that second (Sony) body simply sucks out $$$ that might otherwise be spent with Canonikon, on glass perhaps?
Sony is like this great white shark that smells blood in the water. There was a lot of criticism in the past regarding Sony's e-mount zooms. The new roadmap shows 2nd generation Sony/Zeiss zoom lenses that i assume will offer better native optical performance. For most consumers, a native standard zoom and a native 70-200 F4 is generally what most need and can afford. Flesh that out with some legacy and macro primes and one has a nice package.
Specialists in wildlife and sports are still going to prefer Canikon, but there's not many of those to support a large camera company as you have pointed out.
There was a point in America where the family station wagon got labelled as old-fashioned, not-hip anymore. Ever since then, most car companies are reluctant to label or market a station wagon in this country. Well, Canikon's DSLRs are starting to have that old-fashioned look and feel to them; i expect the culture to turn against them in a sudden and impactful way. Very few people want to carry around the weight and size anymore. Sony (and Samsung for that matter) is systematically addressing and removing any camera/lens issues preventing their adoption by the mass market. They probably don't care that Nikon and Canon will continue to be the market leaders for $10-15,000 600 mm lenses.
(As to me, I just bought a VW Jetta Sportswagon but its really a station wagon
. Needed it to carry around pictures)
