I took the K3 out for a few hours the other day, walking around the Botanic Gardens in Melbourne. It was very sunny with extreme contrast between sun and shade. I mostly shot flowers or interesting plants (e.g. fern fronds) in the full gamut of lights and often mixed sun/shade. I was using the DA 16-85, DA 55-300 WR, DA 10-17, DA 40 Limited, and Tamron 90mm macro.
I have hardly used the K3 since I bought the K1 a year and a half ago. This is largely because my son had been using it a lot (and to good effect). However, he's just bought his own Nikon kit (D850 + several lenses), so I have my trusty old K3 back. I was interested to rediscover my "APS-C vibe".
Some observations:
- Wow, it's so much easier to carry the camera and 5 lenses! I rarely carry more than 3 lenses with the K1, and even then the weight is much greater. This made the walk much more enjoyable.
- On a similar theme, the DA 55-300 was all the reach I needed; I didn't have to lug the damned DFA 150-450.
- I'd forgotten what a great lens the DA 16-85 is! It is so much like the DFA 28-108 on FF. The DA 40 Limited is of course also wonderful, but I use that on the K1 often enough that I didn't need to rediscover it.
- I bought the DA 10-17 fisheye from my son. I'd never used it much before. I don't think the Botanic Gardens (in low light in the fern glade) was the best use of it; I must practice and experiment more.
- The colours are good, but the resolution obviously doesn't compare to the K1. This often doesn't matter, but sometimes it does.
- The built-in flash is very handy. I used it at reduced power for some fill-in when photographing fern fronds in the gloomy fern gully.
- My "keeper rate" of technically good (not necessarily artistically good) shots was far lower than the almost-100% I get with the K1. From my usage, I find the AF on the K1 more precise and consistent.
Anyway, I have a decent selection of good APS-C lenses, so I will certainly shoot more with the K3 in future, especially when I don't want the weight of the FF kit. I will also look forward to the K3-replacement when it arrives. However, I don't think I'll ever go back to APS-C as my primary platform. The K1 has spoiled me.
