|Ricoh GR-D IV @ 28mm: 1/350th sec F/1.9 @ ISO 160. CS5 & Photoscape editing|
As I look through my Tokyo pictures I'm still amazed at the ability of the little Ricoh GR-D IV to be able to capture so much depth of field wide open at F/1.9. Yes, the dynamic range is very limited (shooting lower ISO and RAW helps) compared to a large sensor camera, but the deep DOF you gain is worth it. I'm going to write a Ricoh GR-D IV vs GR (5) comparison again. The more I shoot with the smaller sensored IV, I think I prefer it over the newer, larger sensored GR 5. I'm actually trying to choose between the two cameras, which one to get the 21mm wide angle lens adapter for.
The advantage of having the wide 21mm lens on the GR-D IV is the amazing depth of field you're going to get. My guess is from 6 ft onward, everything will be in focus, even wide open at F/1.9. No need to even autofocus in many situations. The advantage of the new GR is that you have much higher resolution, so you can do more aggressive cropping if you need to. But with a 21mm lens, what's the point of cropping? The whole reason you're shooting with a 21mm lens is so you can get more into the image, not take away. Sorry, I'm just rambling now. I just wanted to share the above image and show the advantage of small sensored cameras. Full-frame is great (I really want the new Sony A7 because of my collection of legacy Minolta lenses) but know why you want it.
