That means that we need less light to make the image.

That means that with our digital 35s, we can shoot a full 2 F-stops wider for the same depth of field as in the film days with the medium format cameras. Many didn’t even realize that they were increasing their depth of field tremendously. I always thought it was interesting that so many film photographers as they transitioned to digital 35s continued to shoot at the same F8 aperture they used on their medium format cameras. We actually end up with even more depth of field our full frame digital SLR and even more depth of field on our APS sized sensor cameras like the Canon 50D.įollowing this logic further - we can see that we can actually shoot the Canon 50D at 35mm optic focused at 10 feet at F4 and actually have more depth of field that I was getting at with my Hasselblad fitted with its 80mm lens. That's why it's so easy to get by with F5.6 on our digital 35s. So on a Canon 50D fitted with a 35mm lens focused at 10 feet with the aperture at F8 we have quite a bit of depth of field 7.28-16 feet or a total DOF range of 8.69 feet. The equivalent focal length lens is about 35mm. Now look what happens to the DOF on the APS sized sensor cameras like the Canon 50D. When shooting the equivalent focal length, a 50 mm lens, on my Canon 5D Mark II, my depth of field at 10 feet is significantly more 7.77-14 feet or a total DOF range of 6.28 feet. The depth of field at 10 feet at F8 when shooting my 80 mm Distagon lens on my Hasselblad was 8.57-12ft or a total DOF range of 3.43 feet.
Now let’s look at the DOF (depth of field) numbers. But as most of us have migrated to digital 35’s, the wider equivalent focal lengths that we used on those cameras give us more depth of field at the same aperture than we had in the old film days.Īn 80mm lens on a 6圆 medium format camera is equivalent to a 50mm lens on my 5D mark II and a 35mm lens on my 40D.
When you look at the numbers below, you may not think so. With a medium format camera F8 gave us plenty of depth of field for the candid images we were shooting. So without any additional whining from me about being at the computer all day let's get right to it.į-Stop Friday: F5.6 - The Friendly F-Stopīack in the old film days F8 was my favorite, friendly F-Stop.
#Henry li sodona panorama video series#
I thought I would do another episode of our F-Stop Friday Series because it gives you some insight into why I do what I do when I'm shooting my images. I was planning to finish a little bit earlier today, get the DPT post up much earlier, but things are what they are. My first priority was to get the PowerPoint done for my presentation on Sunday. I've got it - nobody gets “potty” breaks we just go straight through:~)Īnyway, my apologies for the very late post today. I'm really looking forward to it and I'm kind of curious how I’m going to get through my 400 slide PowerPoint in five hours. The room holds about 70 to 80 people but I hear we have 104 registered for the presentation. I hear from the boys in New York that it's going to be quite the crowd. Is anybody still awake? I've been at a keyboard for 12 straight hours wrapping up my presentation I'm giving at B&H on Sunday. Well welcome to my almost midnight post today at DigitalProTalk.
