Okay, I'll humor you. Are you suggesting that because FOV is mathematically derived from focal length and sensor size, this implies a relationship between these two properties? So there is also a relationship between the width and length of a plane, because those mathematically determine its surface area? And between the price of an item and the amount purchased, because they determine the total price of an order?
i'm sorry i missed that, are you saying that most digital slr camera's for amateur use come with equiped with a compact mid range zoom with relatively slow aperture? haha
Seriously though, this is a great lens, I wish you'd do a mk II with more acurate focus though!!
@USERX15 Perhaps, but without any reference to that 50mm lens at all, how would that point ever come across to the uninitiated? He implies that there is a relationship between focal length (30mm) and sensor size, which is just silly.
If you know enough about camera's, you'll understand what he's saying...it's not his fault you're lacking technical camera knowledge. That's the bottom line. And there is a relationship between focal length and sensor size... as sensor size increases, focal length must also increase to achieve an image with he same Field Of View.
@USERX15 If you know enough about cameras, you wouldn't make (him) or condone (you) the statement I quoted. What you're aiming at is that the FOV of a 30mm lens on a APS-C sensor camera corresponds to that of a 50mm lens on a FF sensor camera. Just stating that "30mm corresponds to the diagonal of the imaging sensor" does not imply superior knowledge, it's simply hogwash. By this reasoning, the focal length of any lens corresponds to the sensor size, making the statement perfectly superfluous.
unfortunately you're still just nit-picking at insignificant subtleties in his choice of words to describe this lens. He could have explained how focal length, sensor size, and effective FOV are all correlated, but being a simple product review, i find that the information provided is sufficient for most experienced end-users. You are right that "30mm" doesn't directly correspond to the "diagonal size" of the cameras sensor, but they are very related...
which he makes clear when he states that the lens replicates very closely the FOV of the human eye, and that the lens is "designed exclusively as a normal lens for APS-C cameras".
I think you're just too consumed by your subjective interpretation.
@USERX15 Nope, not consumed at all. I would have left it at my original passing comment if you hadn't responded to it.
I stand by my opinion that the statement about the focal length / sensor size correspondence is nonsensical: there is no such relation.
Let's agree to disagree about how far off a statement from a self-proclaimed specialist can be, while still being interpreted as factually sound. I'll leave it at that.
that's really a shame, if you have time you could read the wikipedia article entitled "Angle of View". They explain very clearly the relationship between sensor size and focal length, and how FOV is derived from those two components (mathematically). I hope this helps you develop a healthy technical knowledge of cameras. I guess what matters the most is that i understood him, and most other experienced photographers will understand what he's saying as well. adieu!
Sir, you are using an old MacBook Pro.... talking about hiding Apple's icon ain't helping ;)

Why is there a laptop on the desk? Considering he never uses it during the video. Just to brag perhaps.

16 inches min focus distance is just tragic and pathetic.

This is a great lens as long you don't blindly trust the AF at the widest aperture.

@Jessehz I'm thinking of getting one. Are you saying that I must use manual focus at max aperture?

"30mm corresponds to the diagonal of the imaging sensor found on most small chip cameras".
Come again?

@rvdw98
what he's TRYING to say is that 30mm is the APS-C equivalent of a normal 50mm lens on a full frame camera.
