I'm currently using Pentax as my main system, however, until recently, I've come across an deal on an m43 bundle for 1K, and i snatched it. The bundle consist of GX1 and GH2 cameras, and these lenses: Panasonic 14 2.5; 20 1.7; 14-140 4-5.8; 100-300 4-5.6 Olympus 45 1.8 Generally, i think both of the cameras in this bundle were excellent, and i love how small and light it is compared with other systems. so i'm thinking i will have an designate usage for them both, therefore, decided to keep them. GX1 with 14 2.5 would be excellent for my pocket camera so i can have one camera on me at all time, and GH2 with 14-140 + 100-300 would exceed my needs for video and maybe longer shots with the extra bits of reach from the 100-300. With the above logic planned out on my head, i sold the Panasonic 20 1.7 and Olympus 45 1.8 for net profit of $400ish (included shipping, fee, etc). So its been a little over two weeks now, and i'm really liking this set up. its light and portable, and i'm wondering if i should invest more into this system? i'm currently eyeing on the Panasonic 25 1.4, but I also thought about selling the 14-140, and buy the sigma trio 19, 30, 60 2.8? but the 14-140 is just so useful with OIS and efficiency, therefore, i should just buy the 25 1.4 and be done?! Photography is my hobby, and I shoot architect/landscape the most, then everything nature. Any suggestions on what should i invest in next? What would you do in my situation?
