But show me the lens for that small format sensor that can give cinematic like DOF and bokeh as Canon's 70-200 f2.8 L? Or 135mm f2 L? Or go as wide as Sigma 12-24mm lens on FF 5D body?
yea yea you are right, there is no video lens option for f1.2L AFAIK, gotta to associate with Steven Spielberg on that. but.... yea, put it on! put the 70-200 f2.8L on the 5D2 and try to make the shooting, it will be more fun for the handheld type of video. dont tell me about image stabilization feature, i know that. but.. i dont know, never tried that, maybe you did
Perspective is only a function of the subject distance, so the sensor doesn't matter...
you are right! but i only give you 66.666% mark for that 2 points. the exact answer should be:
Perspective is
only a function of the subject distance
and focal length, so the sensor doesn't matter. = 100% mark answer
Bokeh is mainly a function of the lens.
80% mark... 100% = Bokeh is mainly a function of the lens
aperture.
But DOF does depend on sensor size. The DOF is a function of the subject distance, focal length, a few lens parameters like
pupil magnification and exit pupil diameter, and the circle of confusion. The circle of confusion is the largest blur spot on the sensor/film that the eye considers sharp
from the viewing distance.
0% mark... why? you copy-pasted other people's work!
i probably give you some mark if you wrote...
DOF does depend on distance between sensor plane to the focal point.
let me tell you a secret, that nobody on earth do care to put it on the internet. COC is a subjective matter, it varies with each different observer, trust me, it cannot be counted in the engineering equation. just like colors or your favourite food.
thats why you cannot see a value to the exact COC anywhere. canon, nikon, sony, etc etc camera makers got their own value to the COC specification.
but pixel pitch and size does affect COC and its observer, but again... not the sensor size, its the size of a single photodetector on the sensor, there are twenty two millions of it.
man! do i have to read all those theoritical? i'm a postgraduate pal! reading is not my type anymore! photography?! i'm tired already! plsss! not the 1/a=1/b+1/c?!
For printed images, people often use something like the sensor diagonal / 1500 (actual value depends on enlargement, viewing distance, human vision).
The sensor diagonal obviously depends on the sensor size.
yup yup! PRINTING! it has to do with resolution! thats why sensor size (pixel count actually) comes into equation/discussion. if you talk about resolution, then yes... 1/3" sensor lose!
The DOF of a camera with a 43mm diagonal (36x24mm) is the same as the DOF of a 1/3rd inch sensor (7.21mm diagonal according
to Wikipedia) with the aperture value about six times lower (for symmetrical lenses or subject distance >> focal length). So the 5DII at f/16 has the same DOF as your XL1S at f/2.8.
man! i dont understand what you are talking about! are you saying that when i put a 50mm f1.2L @f8 on the 5D2, the image will be similar effect to the same lens @f1.2 on the EOS 350D? (the smallest DSLR sensor)?
Karl is FILMING, as another project, the Art of Electronics. This Vblog was not about the art of electronics.
WHAT! my mother's most miserable nightmare! i thought this is the only one! and i thought the Karl guy is talking electronic about his equipment! i'm skrewed!
maybe i just a kicked out photography school student, not the tools and equipments school. and later i comes into the electronics school and swear by it.
Shafri (being a pro photographer?) might find using a 5D MK2 for video a bit offensive, but there is no mistaking that it is taking the world of video by storm. Some very high end productions are being shot with it, and that's a fact.
i'm not a professional photographer, i'm a part timer and landscape hobbiest photographer. i'm a professional teacher! if you go to the real photog and videog community (i mean the real! not the wannabe!) it will be offensive to use a camera to catch video, much more offensive to videographers. some debates out there!
but for me as a generalist, i dont really care, and really... thats not the main point.
but from positive side... yes! this 5D2 is a winner, an option for a cheaper video equipment that can capture superb quality n resolution. it just simply cannot do all the real video equipment capable of doing.
the real video "monster" is simply unaffordable!
man, do i have to reply all those? stop it plssss. lets talk electronics!
