First, I don't want this to be one of those my camera is better than your camera threads but just an observation on the quality the K3 can produce.
One of my shooting partners had an event coming up and was debating on needing a backup for it. She shoots with a Canon 70D, Sigma 24-70 2.8 and a 18-270. We've shot multiple events before in the past and generally had a blast shooting great images for the customers. Recently she has had a couple of portrait and events she was shooting that were for some really nice clients. She was worried that her camera wasn't best suited for the event. She asked to borrow my K3 with the Tamron 70-200 2.8 and Sigma 17-70C to compliment her on the shoot. Since that first shoot she's borrowed my kit about 3 times to do events and everyone just loves the colors and quality of the images. On the last event I think she only used her camera for two shots. The rest were with mines. Everyone raved about how vibrant and rich the colors were. The exposure was spot on!
I have noticed that since I upgraded from the K5 to the K3 the Tamron 70-200 focuses a lot faster and I'm getting more in focus shots than misses. I really like that combo for portraits. My partner has hinted that she is thinking about getting a new backup camera and I think it's going to be a Pentax. She really got excited when I told her about the upcoming full frame (whenever that happens)
She has constantly mentioned that her camera doesn't produce images as rich as hers and that she spends a lot of time editing her pictures in Photoshop and used very little editing when shooting with the Pentax.
I guess I just wanted to say that it's nice when someone else recognizes the quality that Pentax can produce. Pentax really needs to work on their advertising and marketing!
