It's just that you mentioned the perfect portrait lens, Yours - and since most of my work is in that vein - these are the lenses which have proved to me - to be the most valuable. Also have the 65mm on the RB, and have used that - with some success. On my APS-C cameras, the 10-20 Sigma has worked out well on my Canons. But, on my Nikons - 16-18 - is about as wide as I've ever wanted to go … Sonys, too …

rmorrison1116 got it exactly right, as did some other replies. I come from the film era. For digital I shot APS Canon EOS cameras for some years before switching to a Canon full-frame EOS 6D, and I really wish I had switched a couple years earlier before I took hundreds of great shots of shorebirds. They're great, but they have a fair amount of noise that they wouldn't have had I been shooting full-frame, and printing them 48" wide reveals too much of it. In a nutshell, if you're serious about photography and are likely to go forward with it for a long while, and if you can afford it, buy a full frame camera. You won't regret it. If you do buy a DX camera and lenses to go with it, buy full-frame lenses so that you will be ready for full-frame when you realize you have to move up to it.

In the Nikon world, FX is referred to as Full Frame, DX is referred to as Crop Sensor. In Canon speak, Full Frame equates to EF lens, and EF-S lens requires crop sensor camera. Some FF newer Canon’s will shoot EF-S lens, after a switch to 1.6 crop factor for aspect ratio. Hang in there, you’ll get it sooner or later.

He said in another post he has a D90.

I had some experience working for a for one of New York City's leading fashion photographers during one summer when I was in undergraduate school. He was monthly in Vogue and Harper's Bizarre. He and all his competitors/friends used a 105mm on a Nikkon and a 150mm on a Hansselblad for head and shoulder pictures. Those lens subtly flatten facial features and make people better.

Sounds good

A newbie hint:
Using the “Quote Reply” option as I have done will let us know what you think “Sounds good” means to you.

Yup! Twice the “normal” focal length for any camera format was the recommended typical portrait length I learned in school. That should give you approximately the same camera to subject distance with all of them, which will give you about the same perspective.

Thanks for bringing this up. I have wanted more info myself, and these fine folks have provided just that.

BTW, Stan - didn't give you the run-down on Canon DSLRs before, as you indicated you had a D90 - and wanted to know the difference between DX (APS-C - or crop-sensor) and FX (full-frame) but the way it pans out is this … the pro 1Dx Mk. III (FF), and the pro-level 7D Mk. II (APS-C) both use 20MP sensors, whilst the 5Ds and 5Ds R (FF) both use the 50MP sensor, and the 5D IV (FF) - uses a 30MP sensor (as does the new R mirrorless) whilst the 6D Mk. II (FF) uses a 26MP sensor (as does the new RP mirrorless.) In the APS-C series - apart from the pro-level 7D2 already mentioned, there is the 80D and the 77D - which both use the 24MP sensor, as does the top Rebel in that series - the T7i. The older T6i also has the 24MP sensor, but the older T5i and T4i - use the 18MP sensor, as does the T3i. Not quite sure about the T2i - but I think that one had the 18MP sensor, too. The SL series - now, up to Mk. III - is a more compact version - suited better to street use. Both the 2nd and 3rd - have the 24MP sensor, but I think the original either had the 18MP sensor, or the 20MP sensor. The original 7D (pro-level APS-C) had a 20MP sensor, as did the 6D (entry-level FF) and the 70D (APS-C.) The beginner series are those models which lack the "i" - which basically means they don't have the Intelligent auto-sensor cleaner. So far, the models have included the Rebels T3, T4?, T5?, T6, and T7. The T3 was a 12MP camera (like your D90, Stan) but the later models went to 18MP and now are 24MP. Ok? Thassit!

Stan - sounds terribly complicated, reading it back - doesn't it? … All you really need remember for the Canons are - the 1D series, the 5D series, and the 6D series - are ALL Full-Frame sensor Cameras. Now, then - the 7D series are pro-level APS-C cameras, and the EOS 60D, 70D, 77D, and 80D - are all upper level APS-C designs - similar to the Nikon Prosumer line (D7000 series, incl. the D90, and the D500.) The Canon cameras which ALL sport the Rebel name - are ALL APS-C sensor cameras - the higher up the number - the more advanced they are … the SL series are beginner cameras, with a twist - they have some features of the "i" series, but are still quite small. The most basic entry-level Canons - are the ones w/o the "i" appendix ... they are also the cheapest.

And who remembers filing out your negative carrier to print black frames around the image in order to prove you did not crop the image?

Very good explanation Orrie.

And a very good decision and choice. I own a D90 and it produces wonderful images. You can enjoy DX and FX lenses on the D90 and it will continue to give you great service. Best of luck!!

FYI, I shoot a D600, bought just before the 610 was released, never had the oil on sensor issue.
