Oh wow, PentaxForums, I thought the 3.5 MB attachment limit was per post.
Camera: K-5, crop sections were upscaled to 1024 pixels long side and originals downscaled to 1024 pixels long side as well.
I could have posted original resolutions but that was before I knew I couldn't upload it in PF's attachment feature.
Impression: This is at 2.8. It's not the sharpest, but as a portrait, it's pretty nice. Note that the smoke seems to have very slight wash out his lower face. ISO 800, exposure time: 1/40 seconds (Meaning motion blur may have also played an effect)
2.8, I think it did a good job, and nice color rendition too.
Wouldn't say this is a good shot, but I've only had one shooting session with this lens yet.
Impressions: This is at 5.6. It's pretty sharp. ISO 800, 1/30s.
I'll be coming up with a review later. For now, time to sleep.
