you don't need to worry about refurb Canon gear IMO, sometimes they went through tougher QC from Canon.

Sigma are producing superb primes at the moment which are in many ways better than the canon offerings.
I do hope sigma release a 35mm f/1.4 and a 135mm f/2 as I will likely buy them if they are as good as the canon offerings. Canon's versions are both excellent so the only 'niche' sigma could go for is the lower price.
if this one has the same noise performance as the D7000, BSI sensor from Sony? i would think the D5100 is better than the 600D.
they price it aggressive too even in MSRP.
Lots of rumors that it is a similar sensor, and ISO max is 25600 too, so I doubt there will be a big gap from the D7000. Great specs too as usual, but this time they have these new Sony sensors which they are getting better at a terrific rate.
I can easily see Sony as the main Canon competitor within a few years. I think Sony are exploiting Nikon and all the other brands by selling large number of sensors to them and therefore they can justify a bigger investment in sensor research, since there is a big market. I doubt they could reach such a performance in just few years if they were going to use these sensors only in their cameras. After they reach what they want, they might easily start to sell their older technologies to their competitors. If Nikon won't invest more in sensor technology they might end up in a disadvantage in the future. Of course, this is only true if Nikon is using Sony technology and not Nikon designed and Sony manufactured sensors. Anyone knows ?
... and I think Sigma would do well to spec a 135 mm prime at f/1.8
that would require filter size in the 8xmm size
Wouldn't 75mm suffice ?
Yes. In practice you'll end up with a 77 mm filter.
Canon's 135/2 has a filter size of 72 mm. Same as the 200/2.8
