Are 1/2 EV stops 'real'?
My Canon 50D offers two options for exposure steps: 1/3 and 1/2. I've always stuck to 1/3 but wonder if there is a reason to not switch to 1/2. My main reason for doing so would be to bracket more easily for HDR shots. In order to get a full range of exposures, I figure I need to shoot at -3 EC at +/- 1 EV then at 0 and at… -
Re: Are 1/2 EV stops 'real'?
I'm not sure what you mean by asking if it's real... Your shutter speed and aperture are very real measurements (one in time, the other in the diameter of the opening between the aperture blades). There is no reason other than it being unnecessary that they couldn't be adjusted in 1/10th stop increments. Your camera… -

Re: Are 1/2 EV stops 'real'?
The discussion of the mechanical validity aside, I use 1/2 stops for exactly the reason you quoted originally - why dial three clicks when you can dial two? I like to be able to crank my exposures faster, and I've never really felt a NEED for something as precise as 1/3 stop increments. Heck, my FM2 has WHOLE stop… -
Re: Are 1/2 EV stops 'real'?
I can't see why there would be. The aperture adjustment (at least on my lenses, not sure how Canon's mount works) is just a tab that is slid up or down and the blades close with the tab. There are not fixed "stops." The camera should know exactly how far to move it to create any size aperture. As you stop down, I don't see… -
Re: Are 1/2 EV stops 'real'?
Thanks guys Realized I was thinking aperture the whole time when I should have been thinking shutter speeds! Of course changing shutter by 1/2 stop would be fine I was imagining the aperture changing from the standard: 4.0 - 4.5 - 5.0 - 5.6 to 4.0 - 4.8 - 5.6 and was thinking there would be something physically wrong with… -
Re: Are 1/2 EV stops 'real'?
You haven't ordered the Promote yet? Or better yet, a Nikon (set 9-shot bracket at 1EV steps, turn on continuous shooting, and hold down button on remote release - shooting stops when bracket is finished)... Seriously, I can't see why 1/2 stop intervals would be bad, why do you think they might be? You lose granularity,…
