I have a Sony CX7. How well does the Letus Mini go with such a small and light camera? Any trials and tests from anyone?
Thx.

The adaptor an overkill for the auto-focussing CX7?

There's better than I can comment on this subject as I don't know the CX7 from Adam.

If you are stuck with autofocus and cannot select a manual mode for focus or shutter speed, then there are some difficulties but not impossible to overcome beyond limiting some environments you shoot in.

Any groundglass based 35mm image relay device confers the ability for manual control of focus, a distinctive creative plus where a camera offers full autofocus only.

Automatic shutters which cannot be over-ridden have to be tricked into playing nice. In very bright environments, they may go fast and freeze the groundglass motion which will introduce artifacts.

If there is a shutter priority mode and you lock it to the ideal of about 1/50th or 1/60th sec, the camera will turn around and sting you from another direction by closing the iris which may provoke diffraction artifacts.

Fortunately there should be selectable ND filters in your camera. If not, then you can park an ND filter in front of the still-camera lens on front.

A third way it may bite you is that when you start taking away the camera's options by controlling the amount of light it sees and slowing the shutter speed, it then has another trick up its sleeve of ramping up the video gain when it thinks you are shooting too dark. This introduces video noise from the imager if it is pushed too far.

This forces you into a compromise of being only able to limit the light into the camera by only so much. As adaptors do lose some light, indoors you will likely need additional lighting there.

This is not such a bad thing as it forces you into another aesthetic value-adding practice, learning to use lights for creative effect

If you can learn to live within these means, an adaptor is a great way to add aesthetic value to your images.

Thanks Mate, for that lengthy reply. Much appreciated.

(The CX7 is mostly point and shoot cam, albeit with a little manual exposure/focus options)

Cheers.
