HEy so i'm wondering about buying a lens for a 7D.
My question is do you overly notice the difference say from a 70-200 compared to a 28-300 or vs a tamron 28-300 vs a 70-200 or 24-70... or even a prime of a 50 or 85mm

Do you overly notice the sharpness?... I figure you'd notice contrast and the color. But do you really notice sharpness?

Curious to know...

With HD video, the sharpness of the lens is not nearly as important as the other characteristics (i.e. color, how you like the bokeh, physical handling of the lens, the aperture, etc.) because the resolution of HD video is so low compared to a still image.

Any of your current lenses will provide beautiful results

PRIMES!!!

Your 15/50/85 would be an awesome combo. I wouldnt see a need for more really.

I personally think that the better lenses provide better video quality.
Your 15 fisheye on a 7d would make a great wide angle, and I agree with the previous posts about the primes. They'll look great.

My thoughts exactly!

Other posters mentioned primes, but that's really more about getting beautiful bokeh with faster lenses. HD video resolutions are significantly lower than the still image resolution your camera can produce. You don't need a set of expensive primes to produce very sharp video on your DSLR.

Forget sharpness, you need to think about handling (does it have a good focus ring), blur quality and colour/contrast.

L Lens's generally have the best of these things, but the difference between a good L lens and a good EFS lens is much less discernible in video than stills.

Think about image stabilization, it's surprisingly effective so it's really useful for handheld stuff.
I'd be less worried about super big aperture than others. I usually feel the DoF at F1.4 is way too shallow and just looks a bit sickly to me (in movies). Plus if your wide open with a shutter speed of 1/50 you'll need to stack ND filters half the time.

If I were buying a lens for video I'd get a zoom with F2.8 aperture and a good focus ring to do 90% of the work. I'd wait for the 24-70L replacement personally, as it's due to have IS.
But you have perfectly adequate lenses now.

+1

This is why so many people like the older prime lenses. They (sometimes) have beautiful focus rings and the aperture ring is right there on the lens. That being said though: your lenses will do great.


Also echoing the above comment, please don't shoot everything wide open, haha

Yup and thats fine with me, i'll be using the lens set i have and probably picking up a 35-350mm or a 28-300mm lens just to have all the positions captured.
