TIL that you can only string 25 posts together on Twitter... 😅Conclusion time! Is the A7R4 worth it? It depends. If you are buying a new system the A7R4 will cost $700 more than an A7R2. THAT IS 100% WORTH IT! Here's why... 1/6

The A7R4 generally outperforms the A7R2 in sharpness across the board, especially if you're working with small insects. Plus, it opens the door to PixelShift technology, which you don't have with A7R2. However... 2/6

PixelShift is not really viable for large volumes of images. It is way too costly to store and time consuming to acquire and process. If you need that level of detail, a microscope or SEM will be better, except in a few one-off cases like large display prints. 3/6

PixelShift is also sensitive to vibrations and you need powerful compute hardware to process the images. But I think this gives a glimpse at how beautiful true +100MP single-shot images will be. And perhaps PixelShift shots on those systems will rival some microscopes! 4/6

If you're mainly working with large insects and don't need very fine details, the A7R2 should be more than adequate. I'm going to stick with mine for now. But if @SonyAlpha wants to send me a pre-release A7R5 to play with, I'd be happy to do this again!😉5/6

Thanks for your time. Please let me know if you found this useful or if it was a huge waste of time! Haha, nah, I enjoyed it. I'll put the full resolution images on FigShare soon and do a separate tweet for that.☮️6/6
