Same 1/48th shutter speed was used on both, yes, but we closed the iris as needed to match exposures with the Letus adapter off.

For example, with the 28mm lens on and the Letus we shot at F4, but with the Letus off we shot at F7.3. These f-stops were readings from the Canon A1.

Hope that answers your question.

Thank you Blake,

Great examples! Its interesting how the colors change and look more organic with the adapter and lenses without any extra tweaks...

Hi Blake,
I like to know once you have the adapter on and fixed on the 24mm lens. does it give you much wider view than the widest side of the stock A1 lens?

Thanks
yow siang

Yes, the 24mm is definitely wider than the fixed Canon lens. Not sure by how much exactly though. I beleive the A1 lens is roughly a 30mm (in 35mm equivalent values).

Of course the best thing is you can easily get the shallow DOF look even with the wider angle (with the Letus).

thanks blake am so happy to know that.
As i am asked to do some interior shoot and glad to know i could use my nikkor 24mm lens and need not buy a seperate screw on wide angle adapter.

thanks

Just be ready to use a lot of light on any interior shooting with the Letus. As I've noted in my test it makes the camera rate at about 50 ASA losing roughly 2 1/2 stops. Good luck!

Thanks. that means it looses more light that it states on the quyen website of 1.5 stops. thanks

just wondering if i shoot in interlace mode then later conver to progressive in post will i be able to shoot with more light? as I see using progressive from the camera lcd it looks much darker then interlaced mode.

thanks

If it states 1 1/2 stops of light loss for the Letus then I guess it doesn't take into consideration the SLR lens too? My findings were with both attached to the camera.

As far as interlaced vs. progressive, I don't think that matters. I'm no engineer, but the main thing that has effect on light would be the shutter (and of course the iris). It should be the same I would think in progressive or interlaced.

Note though I did my test shooting 24p at 1/48th shutter.
