Avoiding GG screen grain

[Shooter]

How do you guys guarantee that you have no GG screen grain?

Do you just trust your monitor and your eye or have you done enough tests to know exactly that its not there at all when using various f stop set ups and lenses?

Any tips for the Letus Elite ( HVX with Nikkor lenses) in this regard.


BTW: Do you guys leave the rotation/vibration on all the time during a shoot or do you shut it down between shots / setups etc... (good trap would be to shoot with it off that I can see could easily happen)

It's very obvious when the adapter is turned off as this will show up on the LCD. I would have the adapter turned on at all time unless you're actually changing location and packing up (and if the trip will be short, not even then). Have it on even during break time. Batteries are cheap and the Extreme will run for at least 10 hours continuously so there's no point in risking forgetting to turn it on. Even though you can see the grain, when you're in a hurry your eyes trick you into thinking they're part of the shot.

One thing I wish wish wish with the LEX is that it could stop past 5.6

Lets just say a 300mm 5.6 with 2x converter = a dirty dirty image.

Hell, even a 300mm 5.6 on its own is borderline usable.

Anyway, back to your post. I find ANYTHING about F4 on the LENS (in front of the adapter) will have visable grain, especially on bright/light backgrounds (blue sky/white wall/sandy beach...u get my drift). Yesterday I shot with a 300mm 5.6 an a 2x extender (F8) and in the EX1 LCD there wasn't too much grain, however, when I got home to check the shots, they were un-usable and very very soft.

So, for me...my rule is never above F4 (but in the world of cheap Canon FD lenses, this is hard to avoid).

I leave my vibration motor running all the time and carry lots of spare batteries with me.

Whenever I use an adapter we always check to make sure the adapter is on when we power up as a procedure. Though the risk exists this should be the same as any other procedures the AC does and shouldn't be seen as an un usual thing to do or a "trap". Normally we would turn the adaptor off when powering down the camera.

As for the grain the best way to tell is to shoot test shots on a few different settings and put those shots through the post pipeline you had planned or at least put them on a DVD. The setting with the least grain will stand out when played back on a decent monitor. On location the only other way to tell is of the monitors if there are none then just take the time to look at and concentrate on your on board LCD and view finder. No accuracy though as you are relying on your eyes.
