|Canon EF 24-70mm f/2.8L II USM lens|
The Canon EF 24-70mm f/2.8L II lens has been out for a little while now and although it is an excellent lens I find it just a marginal improvement over the already very good EF 24-70mm f/2.8L Series I lens.
The list price is considerably higher than the lens it replaced but now the Series II lens is already discounted from its list price of $2,299 to $2,049. With the EF 24-70mm f/4L IS coming in early 2013, this lens will not sell too well without IS and its slightly 'slower' cousin with IS at a much more reasonable list price of $1,499 will give it plenty of competition. This explains the discounts coming from a few large camera stores so soon.
The word is Canon has prototypes of this lens with IS being tested but they have no immediate plans to release it until maybe early 2014. This is not surprising because Canon has so many new lenses it plans to release in 2013 and the EF 24-70mm f/2.8L IS II will have to take a back seat for now.
