              Both of them are good for that, anyway you have to have in mind that the lens are very important too, to have nice portraits, you have to buy a 50 mm lens f1.4

              Don't worry, when I was ready to buy the Sony SLT A65, I was very concerned, and I was keeping some thoughts about the Nikon 5100, always having doubts, always searching in the internet something that would tell me " do not buy the Sony" but at that point I was tired, and I bought the Sony, and let me tell you, the Sony is a great camera, the pictures you can take are awesome, they always look very professional, every setting is useful, the resolution is great, colors are very sharp, the kit lens are very good, etc, I always was lookin for something perfect in Photography, and now I found what I was looking for, maybe the Nikon is very good too, but I'm very happy about my choice.

              I was ready to purchase the A65 but have now stopped to rethink.  Image quality is very important to me and a couple of reviews have highlighted the Nikon as producing better quality pictures.  With the 24mp capturing more detail in the shot, I cant understand why the Nikon produces better quality pictures - can someone help me.  Also, the video detail on the A65 is better than the Nikon but I'm not sure it will really matter?  I can wait for inventories but still a bit confused.

              I just purchased the A65 yesterday, 1 have 185 actuations and am very impressed. I'm a newbie to DSLR and absolutely was prepared to purchase the D5100, the problem is you can't buy it right now as there is no inventory due to the flooding in Thailand. I thought perhaps I might have buyers remorse with the Sony but after reviewing the photo's I've taken I don't think I'll look back...

              Hi Stondonmassey and Thyprod, we just take the # of lenses currently available for sale from B&H Photo video by mount.

              Stondonmassey, you suggested we only take Nikon lenses that have AF-S and VR.  I understand your point, keep in mind we already include image stabilization as an advantage of Sony and Pentax cameras, and we point out the lack of autofocus capability with some lenses with the low end Nikon bodies.
               
              Thyprod (4:49 AM, January 18, 2012)
              Add to that, the reviewer has been a bit vague and a little misleading I believe. 92 lenses for the Sony? Doesn't specify new or current lenses... And with the Nikon @ 169 lenses? Sounds like new and second-hand lenses to me. Also sounds like the reviewer may be a bit biased towards Nikon, or simply hasn't done their homework correctly! The beauty about the Sony is that is can accept a lot of second-hand Minolta (MF/AF) lenses which are still readily available second-hand in excellent condition, and some which have better optical quality than Nikon have ever made, because they were once associated with Leica! The glass is the most important thing, remember!
               
              stondonmassey (6:48 PM, November 20, 2011)
              Why are you always saying that Nikon d5100 is compatible with 192 lenses ("169 lenses vs 92 lenses)? Since Sony slt a-65 has built-in motor and stabilization system, and Nikon does not, when comparing these two cameras you should count only  Nikon lenses which are simultaneously VR and AF-S, and you will  hardly find 10 such lenses.
