Finally I got my camera and the 2 lenses so, after spending one day updating the firmware and going through absolutely all the settings, I figured it was time for some action. First target was a park close to my place. Once I've got there with the gear, I realized that I have like 30 min of daylight left, so I got into panic mode and instead of testing different ISO, aperture and shutter speed for the same frame, I've started shooting like there is no tomorrow. I've also come up with the this "brilliant" idea: I noted that somebody said on this thread that the 18-55 WR has a sweet spot at F6.7... so my idea was to shoot in Hyper Manual mode M, use green button to let the camera suggest the settings, lock the exposure with AE-L and then go to 6.7 (or close to it). In practice it turned out to be a very bad idea, because I used ISO 100, so I ended up with a very slow shutter speed. Hands shaky after too much coffee, no tripod... ruined almost all the shots till I realized what's going on. I also had some problems figuring out the shutter speed from the top LCD display: for instance, camera showed 30, I thought this is 30 s (when it's really 1/30s) and trying to achieve a faster shutter speed I went the wrong way, ending up with an even slower shutter speed
I would have realized this if I wouldn't have disabled the status screen to save power. Then at some point I started boosting up the ISO as it got dark, but it was already too late.
When I got home, I discovered most of the shots were blurry and then got frustrated and I really went MEDIEVAL on post-processing. The fact that I was using Lightroom for the first time did not help either
Results: see below.
A bit disappointed about this failure, next day I went to another area with the 50-200. I was a little bit more satisfied this time. Pictures were not that blurry anymore, but I lacked inspiration and subjects so I ended up keeping just 2 frames (of around 25):
Overall I'm very happy with the K5, as it seems it has great potential.... unlike me
A big thanks to everybody for the suggestions and please don't be hard on me, it's the first time I ever use a DSLR.
PS: I need to give up coffee as fast as possible, or get a good tripod.
