Yeah the crop factor is the focal lenth.

100mm lens on a 1.6 is 160mm focal length. So 1/160

Lol, I wasn't expecting to jump into the forums so fast. Still reading tons of threads while I wait for my tank to arrive . However photography is near and dear to me.

Very true.
When IS/VR was first becoming more mainstream (incorporated into more lenses and bodies) I used to get a chuckle at the marketing ads. They often portrayed moving subjects and the "claim" clearer/sharper images. The one I remember most was of a dog (Border Collie I think) jumping into the air and the shooter capturing the hang time
No "IS" sample showed an image of a leaping dog suffering motion blur
With "IS" sample showed a tack sharp dog.
wonderful marketing play to peoples heart strings to open their purse strings. I hope that marketing exec got a good bonus that year

Not "technically" accurate but yes true enough. The resulting image gives you the "same" field of view as though shot with a focal length of 160mm, which isn't quite the same as if it were shot at 160mm. If your at the back of a room, 30 feet from a large window (full frame sensor) and someone then removes the larger window and installs a window half the size (a smaller sensor) all thats changed is how much you see through the window (hence "cropped")...the window itself is still 30feet away. A crop sensor really just has a smaller frame and doesn't "increase" focal length in the most common understanding ("magnification")

To the original comment by Ryan.
Depending on the body itself, it could very well be newer technology as to why it takes as good or better images. Too many people get caught up in MP counts. Canon (and I believe Nikon as well) have finally come to realize that more isn't always better. The flagship "PnS" the G series, they've reduced the MPs from 12MP (G10 I believe) back to 10MP (G11) understanding that there are limits and that you can get a cleaner/better image, especially when dealing with even smaller sensors as found in PnSs.

While not entirely accurate (there are subtle benefits to more MP) for the most part, the average person really doesn't need more than 8MP. Ive got 19x13 prints from my "old" 8MP 1Dmkii that stand up very well against my 17MP files. For the average person who would most likely most often print nothing larger than 8.5x11 and 8MP file is plenty. I have more covers shot with my MKii (8MP) than I do with my mkiv (17MP).

GreenSpottedPuffer is an unknown quantity at this point

Someone mentioned the D700, just a heads up, the new (D800?) will be coming out in spring 2012 and probably be in the same price range, maybe a few hundred more. I wouldn't buy a D700 right now unless its used. I think there is a big shortage anyways because of the Tsunami in Japan. I know the Tsunami delayed the D800 (if that is the new model number as expected).

For what I like to call an almost professional Nikon body, the D7000 is amazing. I don't think you can beat it with a Canon for performance AND price ($1099 body only). I haven't seen a Canon in that price range that can compete. I hate the comparisons it always gets to the D700 because its like comparing apples and oranges. The D700 is FX and D7000 is DX BUT I have seen them compared side by side and was very impressed. The D7000 starts to loose out in lower light though.

One advantage of the D7000 is the glass cost. DX lenses are much cheaper.

My wife uses the D7000 as a back up body (professionally) and I use it for fun...I accidentally had it the other day shooting my aquarium when she was suppose to have it on set for a shoot lol. Luckily she didn't need it. I'm not allowed to touch her expensive body.

LOL I just realized how that sounds...

i've had both and both have their pro's and cons.
I find my Nikon doesn't take the greatest indoor shots - everything comes out a bit yellow but the Macro kicks it!
Canon didn't take the greatest macro shots but it really never took a bad indoor shot.
I think Nikon by far takes the best photo's in natural light!

Are you comparing point and shoots or dslrs?

That was probably me who brought up the D700. I'd like one because of the sensor and the minimal (har har har) price tag (comparitively) but at still more than twice the price of the D7000 it is basically never going to happen for me.

I agree the D7000 is pretty nice.

But you mentioned getting the D700 used ... and well, trust me, I've looked into this and it's a non-starter. Maybe on account of the shortage or whatever, the price of a used D700 is ridiculous. I am seeing $2400 for the D700 body retail (new, for the stores that have one kicking around) and around $2100 for used with several tens of thousands of shutter actuations. Umm no thanks. Given that the D700 is also behind the curve on a few bells and whistles (2008 vintage) compared to 2011 models, you're paying for the sensor, and, it would seem, paying through the nose. Crazy.

Not exactly answering the original question but I'd like to pose an alternative; Pentax. Stabilization is in the body so you don't re-buy it with every lense, any Pentax lense going back to the dawn of time will work with a modern body, and for the price the feature set is very good. I looked at the T3i, D5100, and K-R and ultimatly chose the Pentax. The K-5 is an excellent camera as well but I was on a pretty tight budget.

Getting back to the original topic, it's been mentioned above but I'd have to agree that the modern cameras are pretty decent and that the photographer will play a much bigger role in the resulting photos then the hardware itself. Feature sets will differ a little so your choice will probably come down to which features you find most valuable (video features, burst speeds, etc.) and trivial as it may sound, how the camera feels in hand. I had to drop the T3i from my list for that reason! Go to the camera shop to touch and feel the candidates, and have a good think about what kind of shooting you want to do. That should help you decide.

in camera stabilization is useless. image stabilization is mostly helpful for longer focal lengths. and the in camera sensor stabilizer just cant move enough to compensate the the shake at telephoto focal lengths.

anything below 100mm on a full frame body shouldn't need IS

and if you ever being a serious photographer, you dont want to be stuck with pentax gear.

It doesn't matter what you buy, whatever feels comfortable in your hands, you can't go wrong with any digital SLRs these days

When I was scuba diving in Honduras, I met a National Geographic photographer, he uses Nikon, went on a photoshoot with his friend (uses Canon) in the Desert, Canon was grinding after the assignment, super fine sand/dust was getting into the body and lenses. He told me that Nikon has a far superior sealing system in their cameras and lenses.

Here's a good read

http://www.kenrockwell.com/tech/nikon-vs-canon.htm

First DSLR for me was a Nikon D70, sold the D70 to a friend, then purchased 2 D200's

Personally I use Nikon, have 15 lenses, primes and the preminum zooms.
Have 2 Nikon D200's, cannot switch because I have 2 underwater camera housings for the D200's
All lenses have a Heliopan SH-PMC UV filters on them.

Purchased a D300, then sold it to a friend when the D700 came out, just picked up my D800 last week, just found out Sea&Sea is making a housing for a D800, so I'm tempted to buy it.
http://www.bluewaterphotostore.com/sea-and-sea-mdx-d800

It would save me a lot of weight travelling, won't have to bring my Sony HDV camcorder and housing.

Wrong timing, they won't before I go scuba diving and the end of July to Galapagos Islands (it's whale shark season), then to Machu Pichau

Probably buy the D800 housing for my next trip, muck diving in Indonesia in Aug 2013

I'm a old school photographer, still own a Leica M4P and a couple of Hasselblads, and 2 Nikon F100's and F70. Haven't shoot film in years.
