Manual lenses ...

[GoogleCodeExporter]

Please, describe the enhancement of feature requested below:

Hi!

I use my 400d with manual lenses, then the parameter "Av" is always fixed at 
f/1.4, because there is no communication between the camera and lens. My 
question is: would this parameter can be changed manually in the scripts "DOF 
Calculator" and "Long Exposure Calculator"?.

Anyway, thank you very much to all for this spectacular work in the firmware of 
the 400d.

Regards!

We currently limit the range on those scripts based on what the camera tells us 
about the lens; does not seem too complex to add an option to override that.

it's really not needed. May be only beginners... And then - EMF chip can set 
every parameter needed. Change your chinese chip to EMF or Lushnokov.

You miss the point, it's very useful with the hyperfocal distance, especially 
with different manual lenses (among other things). The DOF calculator on camera 
it's great. I don't need the AF confirmation chip. Anyway, if you are a "Pro", 
you really don't need the 400d.

In my experience after 30 sec of shutter speed does really not matter Long 
exposure calculator settings. It's not real results calculated. Only your 
experience and tries needed. I was try calculate, but pictures or overexposed 
or underexposed. It's for real beginners. I'm shutting about half year, But it 
not really need for me, I'm shutting based real shots and experience. Dof 
calculator may be needed, but you can see all in viewfinder. It's quicker. And 
EMF chip I use only for EXIF focus distance and apperture. And sometime for 
focus microadjustment. If you not need confirmation, don't use confirmation.
