              Just bought a D5100 after seeing the comparison here and it being shown to have better image quality than the D90. However after using the D5100 I am so disappointed. It feels cheap and clunky (albeit lighter), and I am so used to the ISO buttons and the screen at the top with the ISO, shutter, aperture and pics left on card. I also took shots with my 35 1.8 on both cameras and could not agree that the D5100 is better quality. With same settings the D90 took much better pics.

              So get a D90 if you can cheap, otherwise go for a D600 or similar camera that wasn't designed for soccer moms who just want to point and shoot and feel like they still have a DSLR.

              focus motor in camera body is not too important, but you can feel a faster autofocus in canon eos. But i had trouble with my eos 1000d and 500d, since i buy with the kit lens 18-55. Both of my lens kit can't use autofocus mode because the motor is broken, and it happen less than 2 years since i buy it, and the shutter count about 15000. It is different with my d3100 although slower autofocus i feel the shutter more soft and the lens kit last longer

              D 90 is semiprofessional camera. you can learn photography. it is old, but you can still find for a good price, 400 dollars - 600 with 18/105mm

              There is a function button in front side of 5100. and you can assign this button for changing iso levels.

              There is a problem with this comparison, as D90 was released 2008, while D5100 is from 2011! Therefore this is not comparing the same with the same. When it was released, D90 was not considered an "entry level dSLR" at all, in fact it was then the flagship prosumer camera from Nikon. Overall, D90 was one of the most successful digital cameras from Nikon, which is confirmed by the fact that it is still being sold from Nikon, four years after its release. Let's have a look at Nikon D5100 in 2015.

              I have them booth and the D90 feels more professional and handles is much better then the d5100 and the lack of AF motor is a BIG disadvantage of the d5100.

              true the high iso shots are better and the image quality is same as the d7000 but why would you buy an entry level dslr  with 800+ dollars when the image quality is same as the d7000? As 'kman' said its about photography i agree with
              him cause you dont need a 'food' mode or in built hdr when you are a serious photographer .if thats really important buy a point and shoot camera :)

              Here's a link to my flickr pics:
              http://www.flickr.com/photos/stevenjamesphotography/
              Photo's from the last year were taken with the D90, others with the D80 and an older Canon Digital Rebel.
              The wedding photo's were scanned from prints that were taken with my medium format camera's back a few years ago in the good old film days.
              Here's a few more examples.
              *note the  pics below are lower resolution (~100k) as the ones posted on my flickr site although those are also compressed. They all look good on a computer monitor.
              I hope these examples help. Just know that any of the Canon & Nikon DLSRs will produce great photo's as will plenty of other cameras but I have only worked with these.

              I've been in photography over 35 yrs and have owned everything from Hassleblad & Bronica to Canon & Nikon.
              I'm currently on my third DSLR, a D90 and have no plans to get rid of it until at least 100,000 clicks. I sold my D80 for the added features of the D90. I could have purchased the D7000 (a very fine camera) or any other camera for that matter, cost not really an issue. I knew I would be happy with the D90 and after one year and over 9000 photo's I still feel this is the best DSLR for the money.
              I'm using my spare cash to purchase quality lenses, the Nikon R1C1 (I love it!) and more Nikon SB900s (4 so far and 1 SB600).
              Any of these camera's will produce great pictures and will be a joy to work with, much more than any point & shoot so don't lose any sleep. Buy one and get out there and shoot, shoot, shoot!
              FWIW I have no interest at all in video with a DSLR, that's what my nice little Sony HD handycam is for. I also don't like "smart phones". I like the right tool for the job. I don't take photos or video or surf the web with my phone.
              Here's a recent pic from my D90 and the nice DX 85mm Nikon micro (macro):

              NOT ONLY THE VIDEO IS BETTER BUT ALSO THE QUALITY OF THE PICTURES SINCE IT PRODUCES THE SAME QUALITY OF THE D7000. D90 IS A SUPERB CAMERA BUT IT´S IS GETTING OLD. OF COURSE IT PRODUCES WONDERFUL IMAGES, BUT CHECK THE QUALITY OF HIGH ISO SHOTS WITH THE D5100/D7000 AGAINST THE ONES PRODUCED BY THE D90.

              I would like to add though, that this is fine if some one only buys new lenses but this limits your choice of lenses if looking for used lenses. And amongst currently available lenses from Nikon, many AF-S versions tend to be a bit more expensive than AF versions (e.g., 50mm AF vs. 50mm AF-S). In lens focus motors are also not as common yet amongst third party lenses for Nikon, this probably wouldn't be the case 5 years from now though.

              I'm in the Nikon camp, so I will recommend the D90 hands down. The D5100 advantage is in video and newer generation sensor and will have better image quality if you are very picky. The D90 sensor still isn't bad at all though, and will still outperform a T3i.

              The D90 is a completely different animal from the D5100. The design of the D90 is what really sets it apart. Having two dials, a top LCD screen, and additional buttons really gives an advantage to the D90. In the D5100/D3100 changing anything as simple as ISO or white balance will require you to get into the menu system. I can do this blind on my D90, press a button, flick a wheel, much faster. It's a heavier camera, but it's much more nimble in that respect. Plus, as others have mentioned, having a focus motor will let you autofocus with a lot more lenses including older used lenses.

              But to answer your question. Note that I don't know too much about the T3i so not including it in my comparison:
              Color Depth: varies depending on ISO. DxO number will show that the D5100 is ahead, but if you look at the actual chart, that's only at ISO 100 which the D90 does not shoot at natively. At most ISOs, the advantage goes to D90, according to DxO at least.
              Lens Compatibility: D90

              You're right, you can not compare  a camera as the D90 with very much  professional functions with other camera the D5100  for to be  a new camera on the market or for to be   just marketing
