Other than it obviously cropping the picture, are there any disadvantages of a cropped sensor over a full frame if they have the same specs

AngeloRFull frame cameras usually have a lower native ISO and better high ISO performance. Often times they have a higher dynamic range, but that isn’t a guarantee, and high end crop sensor cameras like the d500 can create phenomenal images as well. Also full frame cameras obviously tend to have more megapixels, but cost a lot more.

AngeloRThere are pro versions of crop sensors. Like the Canon 7D MKII. The crop sensors can work great for telephoto lenses. Giving a long lens a longer reach. Conversely it can turn that favorite lens into a different monster. Such as the way an 85mm looks on FF vs APSC. Not quite the portrait nailing machine. The noise issue is real. I had a lot of problems with noise when I was using crop sensor Canon bodies. When I moved from the T6s to the older 6D, my dynamic range, color, and noise performance improved even if I did lose dual pixel AF, and for from 45 to 11 focus points.

CalaverasgrandeWhat's your point about 85mm on crop - is it good or bad for portrait?

dkokalanovAn 85mm lens will simply behave differently on a crop sensor. The crop factor varies, but generally it's going to end up around 115mm-125 equivalent. So it's going to be more tele and less wide. Also FF sensor cameras give you a shallower depth of field. This is part of the magic of 85mm. When you are just far enough away to get the head and shoulders in frame, in most cases the 85's DOF only covers from the tip of the nose to the eyes. The sides of the head will start to subtly blur out, which gives a nice flattering look. (especially on us 40+ folks) On a crop sensor you'll almost always have the whole head in focus, other settings being generally equivalent. I experienced this first hand as I went from crop sensor bodies to a full frame. My lens collection was limited to a 35, 40 and 85mm. On my APSC camera the 85 was really good, but I often went to the 35 or 40mm lenses for their compact size. Also the 85 was just a touch too tele. Making it awkwardly long when doing street photography. I had to keep stepping back! On the full frame 6D the 35 was suddenly very wide to my eyes. The 40 was almost indistinguishable from the 35, and the 85 was much more fun and practical to use! That all said, the classic 85 portrait thing is a wide open (or close to it) shot. Which of course isn't always practical. And not the only stylistic choice for portraits. It will still do that cool thing which emphasizes the roundness of peoples heads even when stopped down though.

AngeloRFull frame sensors are larger, so they can absorb more photons in the same shutter speeds. This makes them better at low-light shooting.
