$3,000 Full Frame vs $1,000 APS-C Camera Setup for Portraits

I have A6600 and the A7IV, I enjoy shooting landscape and bird photography. Despite the advantage of low light for full frame, I'm constantly taking my A6600 for birding trips and landscape photography. Being a lighter setup enables me to be less "scary" looking holding a big camera/lens. I can say its true that the full frame is not 2 or 3 times better, maybe just 20 to 30 % better, usually in iso performance. As such I'm now considering very seriously to sell all my full frame and go back to apsc (A6600 + A6700)

I have both and I reach for the A6400 with the Sigma trio setup more often due to the size and weight advantage and the results are soo close. You helped me realize that. Another great video and service for the community. Thank you!

I think there are a few points to highlight here: APSC f1.4 is equivalent to full-frame f2.1 in terms of bokeh - therefore the background separation is significantly different in my opinion. Also, most of the shots you took were around ISO 100. Full frame widens the gap from crop sensor at higher ISO values ..... the one scenarios where you had higher ISO values - the full-frame at ISO8000 was significantly better than the APS-C at ISO6400. These may be the deciding factors for a lot of people and therefore should be highlighted properly.

Every time I get trapped in sales or full-frame love youtube videos, I come back to your channel and take my A6500 and go out so happy to take some shots. Thank you for another great video 🙌

What an incredible value in the sigma 56mm. That might just be the next lens I purchase. Great analysis, thank you!

Great video as always Arthur

Excellent comparison Arthur! Thank you.

Thanks for taking the time to make the side by side comparison. I think this will help me justify the lens purchases before I step into a full frame body.

long life APS-C ! thanks for another great video. Happy 2022 to you and your whole family. Blessings

Very interesting comparison, thanks!

After watching my A7R2 rapidly fall behind more recent generations I am now pursuing APSC lenses to round out my kit. Cropped mode on my camera gives 18MP, which is adequate if we are honest, so I appreciate your emphasis on APSC Sony options. Good video, I like the results from the 56mm a lot.

Awesome! The video I was looking for. Thank you very much!

A very useful explanation for APS-C and FF, thank you.

I have been using the 56mm and a6100 combo for over a year now, the images it produces are incredible and in my opinion the best value one can get, great video!

Very interesting comparison. Thanks for doing the video.

I love the Sigma 56mm for my Sony a6000 photoshoot behind the scenes!

Excellent comparison video, you have the best Sony lens reviews on YT!

The thing for me which I noticed is the low light performance since I do take more photos at night upgrading from my A6000 to the Sony A7III was a good idea plus doing time-lapse is much easier on the A7III. Mind you the upgrade from the a6000 to the a7III was a massive leap all in all so it made more sense for me.

Great job, Arthur! As always :) It could be interesting to compare the same cameras in video mode. I guess 4k and especially 1080p will be better on ff, but how big will be the difference?

Great review as always, Arthur! Are you going to review the new Tamron 18-300mm?
