Hello!
I have found myself browsing the forums here for the last several years, but have never registered...until today.
*disclaimer, I am a hobbyist that knows some, but has a lot to learn! Please be patient with me in my explanations and what I think I understand.*
Several years ago, when researching for my first DSLR purchase (previously used Minolta SLRs), the information provided here was invaluable! At that time based on needs and budget I went with the Pentax K-r kit that included the 18-55 3.5-5.6 and 50-200 4-5.6 lenses. I have enjoyed learning more with this set up over the years, but feel that it no longer meets my growing needs. I'm a hobbyist, shooting primarily my kids' sports (volleyball, basketball, and both indoor and outdoor track and soccer. Action shots in low light have become my biggest challenge. I feel image quality is an issue too at long focal lengths with my kit 50-200 lens, more noticeably after having the mirror mechanism replaced. I also enjoy portraits, and felt confident doing my oldest daughter's senior portraits. With five, yes 5, more daughters coming up I plan to do theirs as well. So...
I still have a budget, however not quite as tight this time around. I am considering the the K-3II since the K-3 seems to have become more expensive since being discontinued. I will miss the built in flash for certain applications, although I do have accessory flashes. The K-3II seems to be highly rated and a significant upgrade from my K-r to justify upgrading.
Since I'm pretty certain on the body, unless there is a suggestion for a model I haven't considered at a similar price point, my biggest debate is on lens(es). Other than the basics, I admittedly don't know much about lenses. I am currently looking at the following lenses to eventually pair with the K-3II:
1. Pentax HD PENTAX-DA 55-300mm f/4.5-6.3 ED PLM WR RE Lens approx. $430
2. Pentax HD Pentax-DA 55-300mm f/4-5.8 ED WR Lens approx. $340
3. Pentax smc Pentax-DA 18-270mm f/3.5-6.3 ED SDM Lens approx $597
Based on my limited knowledge of lenses, what makes lens 2 less expensive than lens 1? Focal lengths are similar, and lens 2 is "faster", so I'm assuming lens 1 has higher quality optics? I don't completely understand all of the acronyms. Since I find myself shooting outside in different weather conditions, I do like that the first two are weather sealed (resistant). Lens 3 is appealing, since it gives such a wide focal length range and seems like it would be a good "all around lens". Is there truly such a thing? At this price point? With quickly changing subject distance, especially in track, lens 3 seems like a good choice, I just wish it was WR.
Thoughts? Suggestions? Even polite corrections are all welcome.
