Let’s start with the big change, the resolution. A staggering 61mp. I often ask myself, “Do I really need a 61mp camera?” Well……why wouldn’t I!!!!! I remember some years ago saying to people that 16mp is all you will ever need in a camera. However, after owning a 42mp camera my opinion has changed. Why? Well having a higher resolution camera allows for cropping, cropping and cropping some more. Have you ever taken a photo gone home and in post processing you spot something in your image that stands out. You begin to crop all the elements out that are a distraction and then discover your image is around 1200*800 pixels. This may be ok to post on social media, but useless if you decide to print A3. So this is where the high MP camera stands out from the rest. I have cropped a number of images on my A7R2 and could still achieve an excellent A3 print. Mind you there is a downside to all this and it is computer lag. Most image processing software is resource hungry even before you load the image. So processing a 61mp image will require a good machine.
Another few interesting improvements are a pixel shift sensor. I had this on my Pentax camera, but never really used it. I doubt I would use it in the Sony either as it doesn’t combine the images in-camera. You need to use Sonys image edge software or another 3rd party software “Sonypixelshift2dng.” This creates a staggering 240mp image. There goes your laptop up in flames trying to process those images!!!
The camera also has 2 card slots. Which I really crave. I missed that when I jumped ship from Pentax. 🙁
A much higher resolution viewfinder can be found on the A7R4. With my failing eyesight, this would be nice. 🙂
I suppose that is most of the key changes or upgrades from my current camera. The thing I would love more than anything in the A7R5 would be GPS. I think Sony made a big mistake not having it in the A7R4. This would be a big nudge for me to buy. For
