microX - flip module for Redrock Micro M2

[ryvac]

it's great to hear tho, that the softness is gone with the MicroX.
eventho, if the sharpness depends on the setup, it means that with the MicroX is a lot more easier to get the edge to edge sharpness.

btw
on the Redrock tutorial, He said it's not good to close the iris on the camera. so you should leave it open and control it by the 35mm lens....
does anyone know why?
I once heard to open the f-stop for the lens and control the F-stop from by the camera, but now I'm woundering????

Which tutorial is this? The only thing mentioned on the microX tutorial is a general comment to shoot with the 35mm lens stopped down less than wide open (which improves sharpness of the 35mm lens).


My general rule of thumb is set the f-stop on the 35mm lens for the desired depth of field, and balance the exposure with 1) lighting and 2) camera settings (aperture, nd filters, gain, etc.). Generally the sharpest images are keeping the 35mm lens around f4-5.6 and the camera in the same range. That is of course all else being equal. If you need more or less light, etc. then of course you'll want to modify these settings

With my M2, I like to keep the camera at f/3.4 or f/4 and then adjust the 35mm lens aperture between f/2 and f/5.6. Each 35mm lens has it own sharpest stop (or sharpest range), and I will try to hit that and then adjust my lights accordingly.

Obviously this isn't always feasible, but when I can control the light, that's how I do it.

Good input herbal. And if you need to open up for more light, I always prefer opening up the camera's aperture before the lens. Sometimes too little DOF can be easily confused for lack of sharpness.
