I have been looking at the usage of my lenses during the past 18 years of digital photography (the library filter in Lightroom can show camera details and those statistics I copied and pasted into Excel).

Over the years I have been using:
* A Sony DSC707 wide a 38 -190 mm zoom lens (35 mm equivalent)
* A Nikon D70 with either 27-105 or 105-450 zoom lens, or the 27-300 zoomlens (18-70,70-300,70-200 on DX)
* A Nikon D7000 with the 27-300 zoomlens (18-200 on DX format)

I found:
* around 30 % of my images are shot at the widest lens angle
* around 45 % of my images are shot at a focal length up to 50 (35 mm equivalent)
* around 10 % of my images are shot at a focal length above 190
* the rest is fairly equally divided in between, with a slight decrease in percentage from wide to long

So, as result, when considering new equipment, I think I am probably better of with a full frame camera or with a wider lens than anything else (unless I plan to go more specialist with macro or really long for wildlife)

Eye opener for me.

I've never looked at this, though I certainly could as I am a long-time Lr user. I'll have to take up the challenge...

What does your lens angle have to do with full frame?

The DX sensor is smaller than a full frame sensor and as result it covers a smaller portion of the image projected by the lens. This is the crop factor, meaning that an 18 mm lens on a DX sensor result in a field of view equivalent to a 1.5*18=27 mm on a full frame.

Seeing that apparently my usage is very much skewed towards the widest angle available, if I want to cover even more in my images, I could go a step further by using full frame instead of a DX camera (provided my lens is suitable for full frame as well and not only for DX), or I could go for a wide angle lens on my DX, for example a 10-20 or 12-24 zoom, going below the 18-200 I currently have.

It would also be interesting to do this for aperture and shutter-speed; I'm pretty sure that over half of my shots are at the widest possible aperture.

thank you for explaining. interesting that you want to go so wide. I'm sure you can get some interesting shots that way.

I often feel I am unable to get enough into the frame when doing landscapes, so more and more I am doing small panoramic images of just two or 3 frames to get the wide view. The software is so good in alignment that it often does not require a lot of manual adjustment. That's the really cheap alternative, no new hardware required.

In the past I did everything on fully manual. Nowadays I use a lot of aperture priority, so those statistics would be quite predictable for me.
