K10D, why are you comparing both lenses set to 15mm? The Q at 15mm is a 35mm-equiv field of view of an 82.5mm lens. APS-C set at 15mm is equiv to 22.5mm Full frame is a very wide 15mm You are comparing the DOF of a short telephoto lens to that of an ultra-wide angle lens. Unsurprisingly,...

I thought I was comparing two identical focal length lenses to show how actual DOF changes by having a different sensor behind them. Best regards

I thought I was comparing two identical focal length lenses to show how actual DOF changes by having a different sensor behind them. It just confuses things, because the DOF of a 15mm lens, for example, will not change because you put something else behind it. What does change is the the focal le...

People are really confused about equivalence. If you want to take the same photo from the same perspective with two different sensor sizes you will need to change the focal length to get the same FOV. That's why we talk about "equivalent field of view". Also, arguments about how handy the Q is b...

I also don't know why Landscapes and a huge DOF are synonymous? Here's an example by Womble that has real depth.

It had never occurred to me that shot was with the Q Andrew, great stuff. The larger dof is great for candids as there is much more chance of getting the subject in focus.

Sorry, but there are no photographic advantages to a smaller sensor. If you think there are, remember you can simply crop an image made on a large sensor to get the same net effect. I may be out of date, but last time I looked (no more than a few months ago) the highest density FF sensor available i...

That's not an advantage of a smaller sensor it's an advantage of having a higher pixel density. How many Megapixels would the D800's sensor have if it had the same density as that of the Q ? Around 360 megapixels, roughly. In a way, however, it is an advantage of a smaller sensor. This has to...

...Expanding on the above my problem with the whole 'there is no advantage to smaller sensors' argument is that it only works when reduced to a purely theoretical level. For example, to requote the words I quoted earlier: Sorry, but there are no photographic advantages to a smaller sensor. If you...
