For the HC1 it is explained on page 44 of the user manual.

[For shallow DOF: In brighter light I would add a couple of ND filters onto the front. I have found the optimum background blur to be achieved by zooming in at least half way on the slider -and ideally as much as possible- and placing the subject 1/3 distance to background...]

Finally, here is an online DOF calculator to have a play with:

You are correct on both modes. Landscape and nighttime also focus basically on infinity so do not use them for anything close up.

Cool kit

Wow! That IS a cool piece of kit. I have heard of people making home-brew adapters but this looks good and for $300 !! Where's my cheque book!!!

I would be interested to see the results you are getting with this -even some still frames would be great/adequate.

Also, you lose what, 1.5 stops of light? Have you found it an issue?

What lenses are you using on the front? (Do you use a prime / zoom or can you use the camera zoom?)

Sorry, many questions, v. excited!

It looks very nice. There are two setups: the normal one and the flip version. With the normal version, you need to flip the image in post, with the flip version, your image is flipped for you so your viewfinder and lcd have a normal image. You lose around 1,5 stops of light, depending on the lens you use.

You cannot use the camera zoom as you are zooming/focussing on a groundglass image so your camera focus/zoom needs to stay put. You focus/zoom with the 35mm lens. You can however change the aparture with the camera and the lens, but the lens will be the most convenient.

I do not own this lens, but this is what I was told.

Which lenses

Oh I forgot to ask: which type/make of lenses can you fit?

(I have a range of Canon SLR lenses, that would be ideal...hopes for good news!)

Opening the iris to let in more light gives the image a more shallow depth of field.
