Best Compact Camera for You

The manufacturer tells you the ’35mm equivalent focal length’ of the lens but then claims its absolute aperture. Here’s an example. Let’s say the camera has a 1″ sensor, which is a 2.7X crop factor. If they claim it has a 24-70mm full-frame equivalent lens, it’s actually a 9-28mm f/2.8 lens. OK, fair enough.

But then they calculate the aperture at the actual focal length (not FF equivalent). So the lens is a 9-28 f/2.8 aperture is 28mm divided by 2.8 = 10mm. That’s the actual size of the aperture. But if you then list it as a 24-70mm, well, a 10mm aperture at 70mm = f/7 (same math, different direction). It’s not a huge problem, but it makes you think that the lens might act like a 24-70 f/2.8 lens on your SLR and it won’t. ~ Roger Cicala

Roger’s post is an informative and entertaining read. After reading this, I think I am reconsidering “needing” a Fuji X100F ($1300 new) for travel/walkabout photography. I love the design of the camera, and it has just the right size and looks to make me feel like an invisible tourist while walking around. However, I would prefer a standard focal length, and I think I can achieve the same result with a Fujinon XF27mm f/2.8 pancake lens ($450 new) which has a ~41mm full-frame focal length.

I can have my pancake and shoot it too.

  1. I have the 27mm pancake and use it on my X-E3. It works great. That said, I still like the idea of the X100F but I’ll save that money for something else.
