M4 vs A1 studio comparison. Absolutely same camera, lens and flash settings, both on tripod, same positions, both manually focused and triggered with 2s timer.

Can you tell witch is witch without looking at the Exif ?

Well I thought maybe a single hair on her left eye might show the difference, but no. Can you tell without looking at EXIF, Afonso?

No I can’t, not even doing A/B comparisons on a 32” 4K monitor. So far A1’s extra resolution has only benefitted me on achieving more reach trough aggressive cropping on my surf shooting sessions. For everything else (Non-action) the M4 results (Not the usage experience - because A1’s EVF is amazing) are equivalent or superior (Smaller files, better ISO performance, longer lasting batery).
For pairing with fast lenses like the 50 f1.2 A1 also has the edge over M4 because it can go to 1/32000 on bright outdoors. I don’t do landscape or architecture at all, Wich are 2 other areas where A1 probably delivers better results than M4. If I already had the M4 on A1 release day I would probably had gone to a 2x M4 kit instead.

Interesting comments, thank you. I just received my M4 this afternoon and loaded it with Mark Galer's CAMSET file. Boom, instant M4, fully programmed. Now I can think about Christmas with full attention. Thank you for your testing and Merry Christmas.

Yes I am, but I couldn't find the A7iv version, then I clicked another heading and there it was.

Hi, I'm reading and seeing a lot of unboxing video of the a7iv and noticed that Sony don't supply the battery charger but only a power brick.
I'm a bit confused, since I always used a battery charger for my Pentax, how does it work with the Sony? You have to charge the battery inside the camera and plug the camera to a usb port of a PC? How long does it take to fully charge this way?
Would you recommend to buy an external battery charger?

I bought a dual battery charger with a couple of batteries from Amazon cost was £46 (NP-FZ100 Battery Powerextra 2 Pack Camera Replacement Batteries and Dual LCD Battery Charger Compatible with Sony A9 A9R A9S, Alpha9 9R 9S, sony a7iii battery A7RIII A7R3 Digital Camera), I have used them a couple of times and all is good, They recharge the Sony battery in about 2.5 hrs.

My wife bought me a Grip for the camera which also had a couple of batteries with it for about £90.

Sony is frigging cheap. I cannot understand for the life of me how they think it's acceptable to sell a camera for this price and not include a charger. My battery was 100% DEAD when it came and it took quite a while to come up to full charge. While it was charging I ordered a set of Wasabi batteries and a charger. I couldn't survive with in-camera being the only way to charge.

Thanks for your response! It's indeed shameful that Sony don't include a proper charger.
