FF & APS-C sensor & lens comparison

The LensBaby on the 5D is quite an interesting look...
Hopefully they will do a follow-up where they compare the equivalent focal lengths so you can see how FF compares to APS without the zooming effect.

Thanks Mannesty - interesting link. Hopefully Pentax will actually bring out a FF sensor in due course so we can reap the benefits.

We've always known that on Pentax the difference is 50% Not a very good demo because he's made the frame sizes the same.
It would cause problems with say 400mm lenses you would need to buy a 600mm lens to get the same frame on FF as APS-C. Then if you used the 600mm lens on APS-C you fill the frame better with say birds.

And why wouldn't he make the frames the same size? He's not showing the difference in sensor size actually, he's demonstrating the effect of one lens on the two systems.Not a very good demo because he's made the frame sizes the same.
This is a video presentation so no need to use different sized frames.
If a customer wants a 10" x 8" print, it'll be a 10" x 8" print irrespective of what sensor it was shot on.

There is a site that's been posted on here that shows the relative sizes of each sensor.
What the video doesn't show is that his head would be the same size on both sensors, there would be more of the space surrounding him on full frame.

That site is dated 2005, so it is a bit out of date now.

Canon make terrific kit, no matter what anyone here says. They can teach Pentax plenty about autofocus performance and ergonomics...

The op video is a nice graphical representation of the crop factor in effect, of course you'd just use wider lenses on the 7d to achieve your intended coverage.
What is startling is the quality of the video, no wonder TV companies have started shooting with the 5d. A low budget way to get a highly cinematic look.

The laws of Physics as we know them are constantly changing as our understanding of the Universe expands, but what I meant was in relation to how this all affects digital cameras has changed because sensors have considerably changed.

That page is heavily maths based though & they seem to not make any IQ claims one way or the other so I'd still deem it relevant (if a litle tough reading!)
I take your point though, dated conclusions on FF vs APS-C would need to be looked at closely if making claims one way or the other as sensors have improved considerably year on year.

To me, the difference is quite startling when you actually see it in the flesh, as it were.
Beware: Canon kit is used for this demonstration, but I don't hold that against them.
