This is a short test with the tripod in the same spot switching between prime lenses to show how the crop affects the 7D. The subject, ace stand in Chris Clement, was roughly five feet from the camera. This isn't meant to be an aesthetic test to show the difference in image quality between the two cameras. It's a down and dirty field guide for myself and the other shooters we work with so we can quickly figure what lens we want to use on each camera.

We go from 20mm all the way to 100mm with a Lensbaby composer thrown in at the very end.

    Absolutely. That would be awesome. Thanks Philip.

    Hey PBloom,

    What's your take on the 14mm f/2.8 vs the 8-15mm f/4?

    Does the 8-15mm f/4 have more barrel distortion? If so is it comparable to the 15mm f/2.8 fisheye? Because if that's the case then the 8-15mm f/4 is a 2-in-1 deal!


    Thank you very much,

    The other Phil ;]
  • Philip Bloom pro 11 months ago
    one is designed to have very little distortion, the other embraces it. personally i would go with the 14mm unless you want lots of effect shots.
  • Philip Bloom pro 11 months ago
    it's on my lens blog Mike. Thanks. Great way of showing the difference to people. nice job.
  • Mike Collins plus 11 months ago
    We originally did this to keep on our iPads for reference when we are shooting. I know it's always trial and error for me so I figured it could be useful to a lot of people. Thanks for posting it to your blog!

    Nice, simply comparison. Thanks!

  • Philip Han 11 months ago
    No wonder my Tokina 11-16mm can't compare to the 14mm f/2.8 on a Full Frame Body! Hot damn!

    I didn't know the difference was THAT extreme on the wide end! I'm all down for the 1.6X Crop Factor helping my Telephoto out but I love Wide shots more than anything...
  • Philip Bloom pro 11 months ago
    no but at the 11mm end it is around 17mm on the crop, still wide!
  • Philip Han 11 months ago
    Not wide enough...

    I need some light benders than give me 359 degrees of freaking freedom...

    Imagine a ball of cameras mounted with 14mm f/2.8 or 8-15mm f/4's floating around the air...

    Mike - it was great to meet you at the Canon EXPO!

    Very helpful comparison - tho I might pick a nit and say it isn't a "lens comparison" which is how I read it when Philip tweeted it... it really is a comparison of the crop and full frame sensors using the same lenses... but I like to pick nits - just ask my wife! HA

    I'll post this on the planet5D wiki too as it will help folks.

    Thanks for sharing this Mike. BTW...why was the footage of the 7D darker? Picture profile/exposure settings? I know its just a lens comparison...just figured I ask. Thanks again.
  • Mike Collins plus 11 months ago
    I thought I had both cameras at the same F Stop but I think I was wrong about that. We had two simple LED panels up just to throw some light.
  • 3YFX 10 months ago
    Should'nt the 7D require a little more light? Therefore a different fstop?
  •  
  • robotboot plus 11 months ago
    want to get a full frame camera
  •  
  • Tristan Chaika plus 11 months ago
    I thought the 35mm lens on the 7D would be comparable to the 50mm on the 5D, but it looks like the 28mm is much closer. Thanks for the video. Here's a screenshot comparison: twitpic.com/​2mrfz2
  • Evan C. King 11 months ago
    It's true, if you know the math then a 35mm is 56mm where as the a 28mm is roughly 45mm field of view. It's generally easier to match wider than tighter so the 45mm fov works better for a normal lens.
  •  
  • A great reason to make sure you have a full frame body around. Thanks for the comparison!
  •  
  • Andrew Walker plus 11 months ago
    This is why I tell everyone that asks me what camera to get for timelapse to get the 5D2. Full frame is amazing, not to mention the low noise of the 5D2.
  • Mike Collins plus 11 months ago
    The 7D is a fantastic camera but the 5D just takes it's doors off and beats it half to death.
  •  
  • Kevin Huggins plus 11 months ago
    Awesome Post Mike... we all know that there's a crop when shooting with the 7D, but having this actual comparison makes it alot easier to visualize :)
    Excellent work Mike!
  • Mike Collins plus 11 months ago
    I never realized just how much the 7D actually crops the lens. I've seen diagrams but they never seemed as clear to me as this sort of test.
  • Kevin Huggins plus 11 months ago

  • Daniel Blanco 11 months ago
    Really nice!

    Another test that could be useful (I think):

    The same lens on the 5D and 7D, but reframing the subject, so it occupies the same space and position in the frame. So, it shows the change in the "apparent" DOF, barrel distortion in the area of the lens that doesn't project in the 7D sensor...
  • Mike Collins plus 11 months ago
    We may do one like that but for this test it was purely for field of view as a visual reference for myself and the other shooters I work with.
  • Daniel Blanco 11 months ago
    Hhehe, yes, I understand :)

    I wasn't pretending you should have done it, or this one is incomplete. By no means. This is a eye-opening test.

    It just came to my mind while watching it, and thought I's share the idea. I'm not able to execute such a test, since I have just a 550D body and a 50mm 1.8 lens and 18-135 zoom.
  • Mike Collins plus 11 months ago
    I'm sure another test like that would be useful as well.
  •  
  • Ravi Vora 11 months ago
    Really informative, but why is he always sadder when the 7D is on him?
  • Mike Collins plus 11 months ago
    Wouldn't you be sadder going from the 5D to the 7D :)
  •  
  • Jonathan Sanderson plus 11 months ago
    Thanks for this, Mike.

    I like Daniel's suggestion - that could be useful.

    Also: comparing say 30mm lens on 7D with 50mm on 5D / 50mm on 7D with 85mm on 5D. They should achieve comparable framing but nevertheless a different look. Would be interesting to see.
  •  
  • Mike Collins plus 11 months ago
    We can always try to do some more tests if people would like to see them. We start shooting a doc series tomorrow though so give us a little time :) We were thinking of doing one outside in a bright park, both cameras set exactly the same.

  • Evan C. King 11 months ago
    Don't be upset. I actually prefer the crop sensors because I like having something closer to 35mm motion picture FOV. Just get an 11-16 for your wide end and call it day, every other lens is actually working harder for you because telephoto glass is expensive.

  • Lee Okami 11 months ago
    wow, you really have to move pretty far back to get that proper 7d framing huh. I still want my 7D but seems I will be (eventually) using my sisters 5D for film shoots as well. Good test, im definatly keeping this around
  •  
  • brian chang 11 months ago
    this was very helpful. on average, it seems like the dude looks happier when the 5d is looking at him.
  • A.M Visuals plus 10 months ago
    Many people who see this video are biased to the camera with a full frame body, including the people who made this video.
  •  
  • marcus newey 11 months ago
    I fail to see why there are so many posters saying
    "OMG what a huge difference, I must get get 5D".
    Uh, no; just use the apropriate lens.
    You can match FoV between FF and crop at pretty much any Focal length, until you get into the long telephoto range [where the 1.6x crop does have a big advantage]

    As Johnothan Sanderson has suggested, a more interesting test would be to compare lenses that give a very similar Field of View on the two cameras, 10mm vs 16mm, 20mm vs 35mm, 35mm vs 50mm etc.
    Then I suspect you will see only very subtle differences between the two, mostly in Depth of Field [ and Bokeh ] characteristics.

  • Philip Bloom pro 11 months ago
    i actually think this is more interesting...people not realising how much the crop is...if you want to see the difference between the aesthetics watch the zacuto shootout...
  • marcus newey 11 months ago
    but it's irrelivant how big the difference is, you just need use the right focal length lens to match your sensor and desired FoV.
    It certainly shouldn't be a significant factor in the descision to purchase a crop sensor vs a FF, which many commenters here seem to believe.
  • marcus newey 11 months ago
    The only circumstance where my argument falls down is with a few specialst lenses that are not available in a choice of focal lengths, such as the lensbaby.
  • 3YFX 10 months ago
    Marcus I agree. People tend to get "caught up" sometimes. Kind of like the first iPods with substandard features but plenty of "WOW!". "It can hold so many songs!"...yeah, just like any other hard drive music player. Nobody should really be amazed at how much more you see in the frame since you can see the SAME amount for BOTH cameras with the correct lens.

    Now, if you are like me and shooting car and aircraft interiors, THEN you can be impressed, but that is specifically regarding wide angle lens performance. The 7D cannot match the 5D in the area. DOF is another one as well.

    This test is great but I would love to see a true comparison of both cameras. Same exposure/shot and focus on the true differences that I just mentioned. As the poster said, this is a framing reference only. It in no way is a comparison of each cameras visual quality.

  • Johnnie Behiri plus 11 months ago

    For documentary work, I find the 7d much easier because of the smaller sensor so not all is that bad....
  • Mike Collins plus 11 months ago
    We love our 7D also. But they are different cameras. The 7D has become our detail/cut away camera.

  • DC Reels 11 months ago
    Wow, what a difference! Cool video. I like the way the Lens Baby looked too.
  • Mike Collins plus 11 months ago
    The lensbaby is much more distinct on the 5D. We are starting to use it for some interviews. It's got a really dreamy effect.

  • Greg Benedict 11 months ago
    I have the 7D and recently bought a 24mm because of this exact issue. While I love the look of the 50mm 1.4, it just felt too tight. The 24mm was very liberating to me. It is my favorite lens.

    The comments about DOF and compression tests are spot on and I would love to see it as well. I'm at the point where most things are second nature and I'm in the details seeing compression and bokeh that aren't what I want. This is where the sensor size really does change things.

    I eventually plan to go full frame, but I need to wear our my 40D backup first.

  • Julius Tio 11 months ago
    is the settings for both camera the same?? the aperture, shutter speed to ISO Speed?? The 7D got more contrast right??
  • Mike Collins plus 11 months ago
    No. The cameras were not set exactly the same. Both share the same picture profile though. I use the flat profile Philip uses for both cameras. that and both cameras were set at 1/50 for shutter as we shoot 1080/24. The 5D I believe was at 2.8 not sure what the 7D was at. We didn't do this test to compare how both cameras looked. Just as a reference for field of view.

  • Chris 11 months ago
    well.. nice comparison but it doesnt really make sense. it is like comparing a 35mm and a 50mm on the same body and everybody is so astonished why the pictures look so different ^^
    this shows that many people never think about (at least in video land^^) what a the canon 1.6 crop does actually mean.. you have to multiply the mm on the lens to know how it would look on a fullframe camera:
    why dont you make a more realistic comparison like:

    5d 20mm vs 7d 13mm
    5d 50mm vs 7d 35mm
    5d 85mm vs 7d 50mm
    and so on

    but anyways i agree that the 5d gives a little more freedom when choosing lenses.
    because for the same "view" the 7d/550d need a lens with 1/1.6 the mm (for example 30mm instead of 50mm) and 1 stop faster for the same depth of field.

    so if you shoot 50mm f1.8 on your 5d you need a 30mm f1.2 on the 7d/550d (i think there is only the sigma 30mm f1.4)
    if you shoot 20mm f2.8 on 5d you need 13mm f2 on 7d/550d.. but there is only a f2.8 for the 7d..
    but if you shoot your 20mm 5d with f4 you would have the same look with a 7d/550d with the tokina 11-16mm at 13mm f2.8 and it is technical impossible to see a differents.. only if the 5d has better dynamic range. iso would be same because you shoot 1 stop faster than the 5d anyways (or does the 5d has more than 1 stop iso advantage?)

    anyways that are my thoughts about the fullframe versus cropped sensors.. so if you choose a lens that is 1/1.6 the mm (30 instead of 50 / 50 instead of 85) and 1 stop faster it is impossible to see a differents only problem is that the equivalents are not always 1 stop faster but that is only a problem if you shoot wide open..

    long story short: multiply focus lenght with 0.6 and shoot 1 f stop faster and you wont see absolutly any differents

    I think people with a photography background understand this issue better because we have to deal with the fullframe vs cropped issue for so long ^^
  •  
  • Mike Collins plus 11 months ago
    Well Chris all I can say is that the test made perfect sense for me. We have both cameras and like I mentioned I wanted to have a quick reference clip that I could take with me and provide to the other shooters we work with to see the difference in field of view at the same distance with the same lens. So for my purposes it fits the bill.

    This was something I posted because I thought it might be useful to some others as well. I thank Philip for liking it and posting it and for the many people who have found it helpful.
  • Chris 11 months ago
    hi..
    i didnt want to speak badly about your test.. i am just saying that this is more of a different lens test on the 5d.. and another different lens test on the 7d.. but not a 5d vs 7d comparison.. you know what i mean? : )

    i understand that you shoot this to compare the different field of views..
    but shouldnt the conclusion for all the different shooters on the set also be that if you want the look for example of a 5d with a 50mm lens that somebody who is shooting with a 7d on the set has to choose a 30mm lens to get the exact same look.

    i was just confused how many people said that the 5d looks so much better and they seemed so sad that they bought a 7d/550d.. which is simple the result of not choosing a equivalent lens for the cropped sensor ; )
  • JD 11 months ago
    It's surely a little more than 1 f stop different between the cropped and full frame? 80mm @ f4 on 5D would give iris of 20mm? To get iris of 20mm on a 50mm lens on a 1.6 crop factor, the f number would be f2.5 (if that was possible!).
  • GBG Wrestling 10 months ago
    I'd like to see a comparison wuth the object in the same size all along, and the lenses the same (moving back for the 7d). Thus enabling us to see what we lose or gain in focus depth.

  • Anthony Racco 10 months ago
    I'd like to see one with a full scene setup with actors, which compares the the lenses the 5D and 7D each use to capture the same shot; close up, medium close, one shot, two shot, wide, etc. This would be extremely helpful to DSLR filmmakers who have to deal with crop factor and it may highlight a few choice lenses. I'd like to see primes but zooms should also qualify. .
