So much misinformation. Where to start? I teach photography at UMD so i hope i can clear this up for you.

Your fullframe camera- thats just sensor size. Full-frame is the old 35mm film size. Its a tad larger than your aps-c sensors. It also means theres no conversion needed to talk about lenses in mm's. If we say 85mm, its 85mm.

Your iPhone camera needs to be converted into 35mm equivalent. Its about 33mm.

So, your full-frame 35mm is roughly equivalent to your iphone 33mm. And yet... Youre right- 33 is slightly wider than 35. That's independent of the room or the setting.

The end. Go in peace to love and serve photographs to others.

Just shoot. Who cares aboot the numbers?

Except i just put my 35mm lens on my Canon 6d and compared the image to my iphone 6s. The iphone was MUCH wider than the 33mm posted all over the internet. It looks more like 25mm to me.

Numbers shmumbers.
