Well, it's starting to look like I wont be getting the 40-150/2.8 pro lens in time for a trip in January to Costa Rica. I was hoping to take my E-M1, the 12-40 pro and the 40-150 but due to supply and my not placing an early pre-order I won't have the long lens. The wife would also really prefer I don't drop another 1500 right now! (I need to break it off in bite-sized chunks ) I can take a very capable Canon kit but I simply don't want to lug around all of that big heavy gear. This is primarily a family getaway the first half, then a work retreat the second half. Photography is not the primary goal of trip but an important part. I want quality images with minimal worry about gear in varied conditions. While I am not really a birder, I know there are going to be lots of opportunities for photos. Plus monkeys, sloths, snakes (ew!), and who knows what else. I'm new to Olympus so I have essentially zero experience with lenses other than the 12-40/2.8. I need an alternative lens to give me some versatility and reach. While it's 1/2 the reach of the 150, I have been considering the 75/1.8 as it seems to be highly regarded. What else should I think about? I'm willing to trade reach for quality. 35-100? 50-200? 100-300? Oh, I do not plan to bring along a monopod or anything like that so the focal length of the 100-300 would concern me some (as does the image quality actually) Thanks in advance and sorry for yet another one of these questions. I thought I had it all figured out without too much effort.
