Re: Nikon lens multiplier info

I'm not a Nikon guy, but decided I need to include the sensor cropping on their models to go with my previous post about Canon. So here's the info from their usa website:
Looks like the D1X, the D2H, the D1H, the D100 and the D70 all have a lens multiplier effect of 1.5x.
Kind of funny compared to the Canon's EOS 1Ds (1.0), 1D (1.3) and 10D (1.6) ratings - looks like Nikon has some design issues that have standarized around that 1.5 multiplier, because I don't believe that all those models use the same sensor...
For Evo:
Here's the Multiplier effects:
Canon:
300d: 1.6x
10d: 1.6x
1d: 1.3x
1d mkII: 1.3x
1ds: full frame
Nikon:
d1: 1.5x
d1h: 1.5x
d1x: 1.5x
d2h: 1.5x
d100: 1.5x
d70: 1.5x
Fuji: (nikon mount)
Finepix S2: 1.5x
Kodak (nikon mount)
14n Pro: full frame
Pentax:
*ist: 1.5x
Sigma: (foeveon!)
SD9/10: 1.7x
Nikon has "standardized" on the 1.5x image crop as their "DX" standard, probably stemming from engineering difficulties (or just price constraints) in the development of sensors.
as such, they've also developed a NICE series of "DX" lenses, which take into account the 1.5x crop factor:
10.5mm fisheye = 15mm fish on D series body
12-24 G f4 = 18-26 f4 on D series body
17-55 G f2.8= 28-90 f2.8 on D series body
18-70 f3.5-4.5 = 28-105 on D series body
All of the lenses has AF-S (silent wave motor for fast focusing) and they are all ED element glass (extra dispertion for less chromatic abberation) and they all have that nice, semi-professional/professional nikon build.
The 17-55 and the 12-24 are EXPENSIVE, but the new 18-70 should be around $300 and be of similar optical quality to the EXCELLENT 24-85G lens that Nikon has out now.
Canon offers "EF-s" lenses for the Digital Rebel ONLY.
the Kit lens:
18-55 f3.5-5.6 = 29-88 on 300d
55-200 f4.5-5.6 = 88-320 on 300d
These lenses are pretty much consumer build quality all around. I don't know anyone who has the 55-200 (most opt for the 70-300 Sigma, which i'm SURE is opitcally superior and has a TON of telephoto (480 on the 300d). I'm sure the 55-200's quality is acceptable. BUt I think Canon lacks in that these lenses only work on ONE camera. And knowing Canon (they've changed their mount before!) It's entirely possible that the 300d lenses MAY NOT work on future canon bodies. That would take the stuffing out of their "first sub 1k dSLR" march I think.
Sigma (one of my fave lense companies. Check 'em out!) offers one "Digital" series lens:
Sigma 12-24 f4.5-5.6
EX (professional finish) Which equals a 18-36 on Nikon and a 19-38 on Canon.
This lens costs around $500.
I think Nikon has the best strategy with their sensor format and lenses. I don't mind the smaller sensor, as it's easier to engineer. If it gets me 16-22mp (medium format res) some day for 2k i'm sold.
Canon is weird (to me) since they have 1.3x's, 1.6x's and full frame. Plus some odd rebel only lenses, etc.
Sigma's Digital initiative is to be looked at seriously, though the slowness of that lens makes it primarily a landscape lens for me. Though I may get it.
SO the crop factor isn't as big of an issue as it was a year ago. That said, no one ever knows what's happening in the digital world. Hehe
