<p>Thanks a lot for the input guys. It is very much appreciated.<br>
I did my research on the D7200 and it seems pretty good which was out of what I expected. As for DX being good in ISO 3200, it probably is on the D7200, but definitely not the D3200. I had this mindset where the AF on a crop isn't as fast / as good as what's on a FF, but I guess I was wrong. The amount of noise / color noise is noticeably more obvious on the D3200 as compared to the D7200 especially in black / dark areas. There's also this link I found that shows the difference in noise: http://www.dpreview.com/reviews/image-comparison?attr18=lowlight&attr13_0=nikon_d3200&attr13_1=nikon_d750&attr13_2=nikon_d7200&attr13_3=nikon_d610&attr15_0=raw&attr15_1=raw&attr15_2=raw&attr15_3=raw&attr16_0=3200&attr16_1=3200&attr16_2=3200&attr16_3=3200&normalization=full&widget=1&x=-0.8546513639771612&y=-0.15960598525124337</p>
<p>The main reason why I felt the need to change my camera was mainly because there were a lot of shots I missed due to focus hunting. But having the extra stop or two in addition to the AF would definitely be much better. As for the price different between the D750 and D7200, it's pretty signifcant, the D7200 being ~2k cheaper (MYR) than the D750 which is priced at ~5.8k. But is the D750 worth upgrading to full frame for? Or should I stick with the D7200. </p>
<p>As for lenses, I'm definitely looking into getting a Nikon 70-200 f/2.8 regardless whether or not I'm upgrading my body. The 55-300 is something I'm definitely changing and looking to change when the time comes. Also one more thing is that the 17-55 sells used for ~600USD here while a used 24-70 goes for about 2x the price, which is ~1200USD. So it would be quite a lot of money coming out of my pocket to change the 17-55 for a 24-70. </p>
<p>But a FF has this big appeal to it and I guess it's sort of an ego thing as well. I'm definitely not dismissing getting the D7200 now, but is the D750 more worth it in the long run? I mean I would definitely be a freelance photographer, but I doubt I'll be doing it professionally. </p>
<p>I do make do with what I have and try to make the best out of it and I'm not just upgrading from the D3200 because I want better gears, but it's more to I want better gears to be able to get more shots and miss less shots. Here's some photos of concerts/live shows that I took using the D3200.<br>
