Thank you Yildiz for your encouragement.
Yesterday I realized that I have not used my A900 at all in 2017. That made me wonder if I need another body. 42MP sounds so tempting.
As I mentioned earlier, you have a small 'museum of Alpha mounts' in your possession. That's impressive because many already moved onto more advanced bodies and mounts whilst selling the legacy cameras of Sony Alpha.
I think you already made up your mind and, yes, 42 mp and many other features sound more than promising...
And you already sound happy as though you already have them in possession! I hope you get a good sample of each and enjoy a good round of shootings.
Don't forget to share the photos with us !
This enthusiasm translating into new photos, new endeavours with new camera and lenses sounds hopeful.
