Rolling Shutter Speed

Hi All

I shot a music video on the weekend using a Glidcam. I shot location scout footage a few days prior using my Zeiss 50mm Planar T and to my surprise the footage was horrible with that old blur look. I was really disappointed with the outcome considering I spent nearly $2000 on the lens.

So on the weekend of the actual shoot I used my Canon 24-70 and it was a dream come true, it really held it's own with very little rolling shutter issues.

Sorry Zeiss, big let down, big ups to Canon. I am not aware of the science/technology behind why one lens worked and the other didnt on the glidcam, but I can flag this with you all so you dont share the same problem in the future if you expect to buy an expensive lens and have it magically perform like an angel. It may not! Test it! Thank god i did :)

Thanks

old blur look?

Rolling shutter commonly creates what is often referred to as the skew and jello effects- never heard of the "old blur look"!
The thing is, rolling shutter has to do with the speed of the camera's sensor and how much jittery movement is going on. The further the focal point of the lens, the more exaggerated the effect will be. However, two lenses with the same focal point (50mm, for example) will exhibit the same about of rolling shutter problems when used in the same way.

I suspect the reason your Canon 24-70mm worked better is because you were backed up more to the 24mm side, essentially half the distance of your 50mm Zeiss. The general rule is: The wider your lens, the less jittering/jello.

Try your test again, zooming the Canon out to the full 70mm. I think you'll find the footage is far worse than the Zeiss.

The Zeiss is an excellent lens for sharpness clarity, that is why it is so expensive. But it does not offer a wide FOV or IS, so you need to know the limitations of your camera and how it will be used.
 
I think the OP might be thinking of regular shutter, not rolling shutter. Perhaps he found there to be too much motion blur and he dislikes that?

Lenses don't have shutters or otherwise effect the shutter speed or motion blur either.
