The NIKON Thread (Talk About Nikon Stuff here)

"Sensor manufacturer Sony " according to DPreview. Then again, manufacturing is not the same as designing. Does it really matter though? The stuff they put into these things come from all over the place and it's hard to tell which factory belongs to which brand.

There are other brands using the same sensors, but even the RAW data will be different because they tweak them differently, put slightly different UV/IR/antialias-filters on top, etc.
Still, I don't have any evidence they're the same, but that's what I got from reading around

Yeah, I thought the D100, D70, D50, D70s, and D40 all used the same basic 6MP sensor, just with different supporting casts.

is there an equivalent to the 100-400L for nikon?

I haven't used the 100-400 but the 80-400 from Nikon isn't all that special really. In the end it gets the job done; its just not a great lens.

Well they cost about the same, both have image stabilization, both around the same zoom range, and are the same speed (4.5-5.6). So I consider them equivalents.

As for actual performance, I've never used either so can't comment on them.

I wonder how fast it auto-focuses. Moving heavy glass from 80 to 400 can't be an easy task for any AF motor.

Hm? Your hand moves things from 80 to 400mm. It's 4.5-5.6 which is not really heavy glass. All the mega primes and something like 200 2.0 all are very fast in AF. The 80-400 is kind of old though. 5.6 also doesn't help the AF system which needs to think longer as opposed to a 2.8 lens.

Oh yeah. I've mixed things up haven't I

Nikon has a 200-400mm f/4 VR. It's a gold-ring lens (sort of equivalent to Canon's L line) but I think it is very expensive. However it's a fantastic lens from what I hear.
