You obviously didn't read what a1ex wrote above 

seems like he is just on the way to do this function...

hmm thats interesting
i should try that

but now this push me to idea

how about to implement dark frame in magic lantern settings

so that we can get automaticly clean images?

yeah if magic lantern wasnt existing
i would probably buy black magic cinema camera or pocket version for sure

also any developments in new DSLR without compact flash card doesnt interest me in any ways

i have to test that dark frames things
if anyone explain it little bit or send link?

I explained it in my post. Also note that usually DR is wider at lower ISOs.

And please stop this trolling. Obviously after all the forums and nicks that you've gone through, you've grown some hard forehead of yourself to ignore remarks to your meaningless posts.

I guess soon the time will come when we on the forum will have to address the moderator to keep this forum clean and acceptable for those who are hungry for 50D RAW info, rather than having to sift through someone's egotistic garbage...

yeah just become professional
and then complain about my posts people)

Hi all, I recently was shooting on BMCC and decided to make comparison of BMCC vs 50D.

how come u make test on ISO 400 of canon 50d?
watch video above i made on ISO 3200
and thats even without ETTR stuff

but thanks for BMCC raw file

i made it look like it should be
here is 100% crop


and here is full size picture enjoy
http://s54.radikal.ru/i143/1308/8d/a8e845d0e293.jpg



ps
dont make things look ugly people
this cameras are pushing maximum to look good in extreme conditions

whats the point to look for noise on ISO 400-800?

better show how u handle it on ISO 3200

Hey guys UWA lenses that aren't fisheye do exist.  The Sigma 8-16mm f4.5-5.6 is a rectilinear wide angle.  It's also a good option for Crop Modes.  Better than the Samyang 8mm Fisheye IMO.

There is also a Sigma 10-20mm f3.5 which is another nice option.

relax i made a test on it
coming in few time

updated:

okay here it is
18 mm f3.5 from Nikon 18-105 lens on crop mode canon 50d gives like 85 mm f16
and this video is shot from distance of 50 cm only.

also if you see focus is able to move here and there
its possible because the distance is small for subject
for simulations of shallow depth of field

that is ISO 3200

anybody knows why video is kinda choppy?
something wrong with frame skipping or shutterspeed  or FPS override or what?

@menoc - http://www.ebay.com/itm/Isco-Iscomorphot-16-2x-Anamorphic-Cinemascope-Lens-/200956832944?pt=Camera_Lenses&hash=item2ec9f5ecb0 right on the money and a seriously nice lens for video. You'll be able to shoot over 2.5k 16:9 with this. I would buy it myself if I could.

Pair it with a Helios 44M-2 or an old Nikon 50mm (as both flare) and you'll get pure Hollywood

yeah if anyone wana sell such thing i would like to buy)

updated:

okay dudes
jokes away

i made a serious video test raw canon 50d without camera shake
(i used my special anti shake tool this time)
u going to be suprised to know what is it in few minutes... or hour

True, so not viable for normal cinema use (big and bulky tripods, optical stabilizers, and great spaces, not viable for indoor use, and so on)

yeah but good for spy work)

also i see no problem with shooting on 1582xwhatever resolution over 1920xwhatever
its just 20% gain

and 1582 is good enough

if want more why dont go for 4K at once?

@dlrpgmsvc

we can actually record in crop mode with shallow depth of field
but it needs huge distance and telephoto kind lens

A Tokina for $400 is very much a possibility. The other option is to get an anamorphic. There are a few 2x for around that kind of money and it will give you a wider field of view with cool bokeh and flares. It's actually a much cooler option in my opinion

i want anamorphic lens for canon 50d raw video

do you know which ones are on sale?

i just have no idea about this thing

id like to buy one from amazon.co.uk or some shop
not familiar with ebay things

I see what you're saying. There will still be some distortion around the edges . . . the price sounds right though.

this is what you going to get on 8 mm rokinon
i love fisheye
im going to buy this one
coz it gives 180 degree view

and normal wide angles only like 110 degree



ps that little distortion u get on crop mode can easily be fixed in program


and for normal things i can use 18 mm nikon lens i have on crop it gives like 85 mm
18 mm is on any kit lenses. like 18-105 from nikon i have

but if u want to get such thing u can buy even cheaper versions like 18-55 mm

of coz if u have like 600-700 buck u can get tokina
or get sigma for 400-450 buck

otherwise fisheye rokinon 8 mm is only choise for 249 buck

Interesting . . . but I'd like a non-fish eye lens though. How difficult is it to defish video and what would be the results?

first of all when u crop in the lens
you already defish it pretty much

secondly if u dont shoot something very close
then u dont have this perspective distortion that all wide angles giving
like pinnocio long nose etc

so u dont have to do anything about it pretty much

I need a recommendation on the best cheap ultra wide angle (14mm or less) lens to shoot in crop mode . . . under $200 would be nice.

Anybody?

this is what u are looking for 249$ Rokinon 8 mm f3.5

The DOF changes because you are changing your camera to subject distance!

Seriously, monti or silkway or whatever you prefer to be called, your comments on here are making me think you're just a troll.

This used to be a helpful and polite forum but lately it's turned into dvxuser, such a shame.

seriously i didnt intend to move from subject
it happened accidently

but even so you can see the difference isnt it?

just its kind of test for intelligence
coz complaining about this is rude

anyway tomorrow i will make another test

maybe problem is that magic lantern doesnt give you exact framing preview in crop mode?

or you know what? im going to make one photo test right now. just give me couple of minutes

updated:

okay test is done
and its going to blow your minds
im going to post it in a second

apdated:

okay here is the test:


Click here for full size review:
http://i036.radikal.ru/1308/87/53761570200d.jpg


for those who still in doubt
here is x10 crop


the 2 crop images are blurry because of camera shake on long focal distance 250-500 mm with no stabilization

OKAY THE DISCUSSION IS OVER
I WAS RIGHT
EVERYONE CORRECT YOUR BELIEFS ABOUT DEPTH OF FIELD IN CROP MODE =)

(This is real test on canon 50d)

Hey Monti
A lot of noice on this forum
May you take a brake for a while or take from courses?
muchas gracias

no way
im excited now

maybe when i get bored then i leave

but thanks for your compliment to say that im most active poster here
i hear this on every forum and community i pass by during my life

i like to bring something into somewhere

@Monti : your test is not correct. You are progressively going away from subject (the Matchbox) by lens or by 50D phisically (not important). You have to test at the same framing the normal, the 5x and the 10x, so that the Matchbox occupy the same area on the sensor. It is obvious that more you go away from Matchbox and the more you have DOF. Can you redo the test in this way ? Only in this way we can judge

yeah i noticed that and im going to redo a matchbox in frame test on photo mode another time

but what you can not see then is scale of depth of field magnification
in here its kinda shows that the difference noticeable on wider area or so...
coz i started with matchbox and then realised that next DOP is just too wide for that frame
so need to make framing wider to get other details in frame
simple matchbox wont show much here and there

so i better start from table test from beginning

@Monti - A little tip. If you don't have a tripod, rig or stabilizer put the camera on a cushion and put that on something solid. This will reduce movement and still allow you some degree of tilt and pan. For handheld you can also use your camera strap - by putting it around your neck or body and pulling it taught. It won't eliminate movement but will reduce shake a little.

yeah nice tips
but if i want smooth paning i have a better solution

i just dont use it for crap video tests and keep for serious work)
also i like my shaky style it fits to war songs like in war movies of 1945 year

ps and i have all kind of rigs and stuff too

Hey man wow great test so usefull really.. all that talk about composition for this haha! seems like you where drunk and on acids when you shot this man.

Btw I don't know where you found that komputarbay cards were bad, I shot 400gb+ on two 32gb without a single issue. As for the issue a few pages back, the poster probably could have recovered his card. There is a lot that can happen and corrupt a card/flash memory disck but it can be fixed most of the times with the rigth partitionning/formatting tools.

talking about compositions
i just checked it and it looks alright
(the rule of thirds is on the place and other rules of composition too)

there is camera shake coz i didnt use tripod and its manual nikon focus with no image stabilization prime lens 50 mm f1.8 - hard to pull focus with one hand and hold camera with other hand if u know what i mean

especially when this crop mode makes it 250 mm and 500 mm with no stabilization
that is another reason why you dont want to use crop mode while recording motion picture

ps i dont mind crashed and fixed komputerbay cards
i just dont want my footage to be lost during this crashes

And Auto Exposure http://flic.kr/p/fEjWBG

teach me auto expo plz

ps seems like those komputerbay cards crashing like wallnuts

maybe i should better stick with my lexar x1000 cards

okay here is depth of field test on crop modes raw video with canon 50d
first normal mode then x5 and then x10

i dont know what happen why the framing isnt same
also no VR so shaky video

watch in HD or Full HD resolution

i know this test sucks
but to me i can see what is going about

later i make photo test that is more obvious
that on crop 5x and crop 10x the depth of field becomes wide like table

"Circle of confusion"  - yep! that describes this subject nicely 

okay i done test
results as i expected
will post soon

Totally wrong again. If you frame the same size object, the dof is the same at all focal lengths. http://www.cambridgeincolour.com/tutorials/depth-of-field.htm

dont mess with this up dude
yiou just confuse yourself
im making real test to show the thing

We all would but no can do! HDMI is 8bit and nowhere near the bandwidth needed for raw video.

yeah then...
if i wanted 8 bit prores uncompressed HDMI output
i would buy Nikon d800 or Nikon d600

but i went to Canon 50d
coz raw video is raw video

its hollywood standart.

(ARRIRAW: 2880 x 1620, uncompressed 12 bit log without white balance or exposure index processing applied. )
http://www.arri.com/camera/digital_cameras/cameras/camera_details.html?product=8&subsection=technical_data&cHash=177d18e5da12e11481110e620f560c80

but in reality the difference here is
14 stops of dynamic range

it means dual iso in video

like the one on 5d mark 3

also the resulution is like 4 times higher means bitrate 300 mb/sec
and external hard disk for 1 tb or more

other than that - canon 50d is pretty much a hollywood camera
again - it happen thanks to magic lantern team

generally to understand what is raw video dynamic range or HDR video
for those who dont know
is when you see lots of white and black stuff on same screen
and colors are also very different filling up this space

on anything else than raw video you cant go that far
coz raw contains wide range of data between under and over exposed data from sensor

and now some fun for developers
the Matrix remake hehe

The d7000 thing is not going to happen, there is just 1 guy looking into it and they are still figuring out basic stuff on the firmwares, don't even think of being able to use the two card slots to give 40mb/s. The test he made was writing around 20mb/s so... And it was just junk, no actual images.

yeah thats what im saying
i just didnt want to wait for him to do that nikon d7000 raw video

and went to buy myself a canon 50d to follow up with magic lantern guys for raw video lately

that guy will never make it alone
unless people from magic lantern would go for it and sort that out

20mb/sec isnt too bad
canon 600d is doing raw video on 20mb/sec on sd cards as well

How much slower? I was waiting for it to hit the main tree at some point.. even HDMI plugged in makes a difference.

oh btw what about HDMI tweaks for canon 50d raw video on tragic lantern side?

id rather record on external recordre like atomos ninja 2
than trying to fit in compact flash card footage that takes 4 gb per minute
