Exposure Issues - Stock Lens

[Joe Shaw]

I'm hoping someone is going to point out something simple I am doing wrong, but I went out to shoot some stuff today. The weather was cloudy and fairly overcast. My problem was that to get a decent exposure I was having to crank the ISO up to 800 and 1600 at times. Which does not seem in anyway right.

I know the stock lens is slow, but that slow?

I'm shooting in the Movie Camera icon mode on the main dial, with auto everything off.

Any suggestions or ideas for checking if this right, I'd appreciate it.

All I have to compare with is my trusty old Canon AE1 Program. Not sure I trust the needle meter in that. But perhaps it could be useful?

Would someone who has one at least give me an idea of what kind of ISO they are shooting at under normal daylight conditions with the stock lens?

what shutter speed were you using?

[Joe Shaw]

I'm trying to shoot at 1/50.

This is my problem as I see it. Today, I point the camera up at the clear sky. Lens is at its widest. ISO 100. Shutter 1/50. At f4 I just about get correct exposure. If anything it is slightly under...

No filters etc. Auto ISO off. Intelligent Exposure off.

Joe,
It's pretty overcast here in Nagoya too. Did a quick test and with aperture wide, shutter at 60 (for 720 SH), and ISO 100. It was a blow out...as expected. Had to stop down to 14 to get semi-decent exposure on ISO 100.
Your situation sounds fishy...
Kholi has an interesting theory about low ISO and increased noise but in any case something isn't right.
What aperture are you using? Shutter? etc...

I'm sloooooooooooow

[Joe Shaw]

Appreciate ur reply though. Clearly, I have what we like to call - a lemon.

[SonicStates]

I'll see if I can replicate what your talking about...minus the lemon part

[Joe Shaw]

That would be great. I don't think I have any settings wrong and I have reset the camera just in case. But for some reason, there is a definite exposure problem with mine.

Best way to check is borrowing a old fashion light meter and compare with the camera's read-out.
