This is a useful resource if you want to directly compare sensor output - note the D610 doesn't really pull ahead even at 6400iso and if you compare it to other brands (I included a Fujifilm 26mp APSC body) it is well and truly beaten even though it's sensor is larger https://www.dpreview.com/reviews/image-comparison?attr18=daylight&attr13_0=nikon_d610&attr13_1=fujifilm_xt3&attr13_2=nikon_d7200&attr13_3=nikon_d5300&attr15_0=jpeg&attr15_1=jpeg&attr15_2=jpeg&attr15_3=jpeg&attr16_0=6400&attr16_1=6400&attr16_2=6400&attr16_3=6400&normalization=full&widget=1&x=0.5763247189672414&y=-0.18858878066013512

You will get a tiny, and it is a tiny gain in noise levels at very high ISO's switching from a D5300 to a D610 - BUT - you will loose your 1.5x crop factor so your 600mm lens stops acting like a 900mm which mean you are going to have to get closer (we all know this isn't usually possible) or crop during post production which will lead to a net loss in image quality. I appreciate you have already made a purchase but if you can out it on hold it might be worth doing so. The AF points on your D5300 cover a larger are of the screen which can give a significant boost to your keeper rate - your current camera has a larger, higher quality and fully articulated screen which the D610 lacks, might not seem like a major thing but trust me, once you are used to one, they're hard to live without. I don't know your exact overall budget but a D7500 or better still D500 would give you a far great gain in overall performance. They are faster, have better AF systems, more modern processors, articulated screens etc. The D500 if its within budget is basically a baby D5 and is frankly astonishing for the money. All current mainstream camera use CMOS sensors, they have done for donkeys years. Processors are a separate thing altogether and they gain significantly in performance with each generation.

Which camera are you using now - because the D610 sensor has a poorer performance than many current APSC sensors?

Out of curiosity what are you hoping to achieve by changing the size of your sensor?

Oooo....just spotted this. Thanks flower, it was a spectacular morning to be out on the coast

Thanks very much - I'm very lucky to live where I do and have a fantastic coastline to photograph

Thanks very much - I've told Thomas he has won and he wanted to know what his prize was ? Kids man

One of the Best camera ever made - enjoy

This is one to watch as well as listen to - absolutely mesmerising

I somehow seemed to have been hoodwinked into being a judge so I guess I had better pick this months 3 winnings shots. In their original chronological order: #1 - a long lens and a teleconverter made for this excellent 'macro' shot by Clicker #2 - There are meant to be these critters near us but I have never managed to spot one, very impressive Ryewolf #3 - Look at that colour, gorgeous that JohnP

Been baking again- had some left over chilli con carne so knocked up some pastry, made mash with caramelised red onions and cheese mixed in then made a tray full of pies

That’s typical for many cameras, has been for a while, as it’s a very unusual way to access data.
