The focus was on the plant's, and I did zoom in and got it as sharp as I could.

I know shooting in 1920x1080 24 or 30 would yield sharper footage, but I am just showing what my 720p footage looks like because i feel like it should be sharper

And i just sold my 50mm 1.8 because I didn't think i would ever use it if i had a fast zoom lens like the tamron, but i'm already regretting selling it lol

16-235 is NTSC color space with setup. digital video has no setup, therefore its RGB 0 = 0IRE, and RGB 235 = 100 IRE.

the canon codec compresses the camera's output. the camera will output whites to 110 IRE on its V out, but the codec will compress the top end down to 100 IRE.

for all the scope'd tests 60D Dynamic Range : Part 4

You might keep an eye out for an older, used Canon 50/1.8. The metal body ones are inexpensive and have better focus rings for video. And they are quite sharp, competing in sharpness with lenses that cost five times as much.

So, why are they so cheap? Because they're small, "only" f/1.8, and Canon made a gazillion of them. :)

The look of your shots reminds me a bit of the Canon EF 70-300/4-5.6 IS that I first bought for the 5D2. On wildlife stills, the fur looked ugly with a lack of sharpness, yet a "crunchiness" that just didn't make sense. I think it was a micro-contrast issue with the different colors shifted slightly. I replaced it with an EF 200/2.8L and the shots from this lens blew me away on day one. You could cut edges with a knife.

My 5D2 doesn't do 720p. It would be interesting to do some 720p shooting with a nice prime. At NAB, Vincent Laforet recommended shooting at 720 for most web delivery. He felt that it made critical focusing less critical.

From what I've read about the tamron, it's supposed to be super sharp, and from the pictures I've taken, it looks to be sharp, so I don't think it's a lens issue

And about those metal 50mm 1.8's, are those one of those older lenses that you need an adapter for? Because the only 50mm 1.8 I usually see on ebay is the same model i've had

The older EF 50/1.8s don't need an adapter.

It might not be a lens issue, if your photos are sharp. In fact, it would be interesting to snap a photo of your next test, color grade it as you would like your video to look, and then try to get your video to match it.

How do I find these older 50mm? Do I just search ebay for 50mm 1.8 and look for metal ones?

You can tell the difference by looking at the lens or its photo. Here is a comparison...
