I recently returned from a very short trip to Costa Rica. I'm going to make this post a little different than the ones I normally do and include more gear talk. A lot of the pics I took broke a lot of the rules you will read when using m43 gear. Don't use the p20 for moving subjects, high iso is super noisy, the o12-40 is soft at 40mm, the fl-600R is under powered, the o75-300mm is soft at the long end. My point is there is some truth to these but they are not hard and fast rules, if the shot requires you to push the limits, do it and you may be surprised. Gear I used E-m5 II, E-m10, p20, o75, o12-45, o-75-300, fl600r, Haida 10 stopper. I purchased the Oly 75-300 II specifically for the wildlife on this trip and sold it on my return. I found it a great lens, super light and I could get consistently sharp (not super tele sharp) photos with it handheld. Street Walking by Siftu, on Flickr Taken with the p20 while my son was walking along. I was also walking along and quickly shot this when I noticed the interesting footpath. Focus is slow on this lens but you get used to it quite quickly and the size more than makes up for it. La Fortuna Falls, Costa Rica by Siftu, on Flickr I used the O12-40 and Haida 10 stopper for this shot at f10 (oh no the diffraction!). I really love the 12-40 for landscapes. When you go into manual focus and find that hyperfocal with peaking and magnify it really does shine. Proyecto Asis Animal Rescue by Siftu, on Flickr This was at an animal rescue. This spider monkey was raised by humans and likes to hold hands. I used the o75 to get the bokeh I wanted for the cage. Fulvous-vented Euphonia by Siftu, on Flickr The o75-300mm at 228mm and 1/400th according to EXIF.. I really did not have a problem hand holding this lens when mounted to the e-m5 ii. I never once used it on a tripod and could consistently get sharp enough photos at 1/250th or even less. Walk Amongst Giants by Siftu, on Flickr In camera HDR1 mode taken handheld. Sure not the sharpest but prints perfect. Green Violet-ear Hummingbird by Siftu, on Flickr My favorite hummingbird lens is certainly the o75 at f1.8. I was able to shoot wide open and get a shutter speed of 1/2500th. I have taken pictures of hummingbirds using this lens many times. Check out my flickr feed for the Violet Saber Wing Hummingbird shot taken at iso 3200. Side-Striped Palm-Pit Viper by Siftu, on Flickr This snake is poisonous and was in the wild. I was trying not to be bitten when taking this so didn't look at my settings too much. I got back and realized I shot it at iso 3200. This is a sooc jpeg cropped with NR set to OFF in camera. Some Rain by Siftu, on Flickr Rain with the o12-40 on the em5 ii. No problem. Manuel Antonio by Siftu, on Flickr Another shot with the o12-40 and the cheap Haida 10 stopper. The only thing I need to do in LR is a slight color correction. I use the circular ones for travel as it's a lot easier than the cokin/lee square ones. Howler Monkey by Siftu, on Flickr Not a great photo but just demonstrates what can be done which a fairly cheap lens. It was raining, it was dark and the monkey was a good 20 meters away. The o75-300 at 270mm and the fl-600R at full manual power combined with iso 2000 made this shot possible. White Faced Monkey by Siftu, on Flickr This was a super high dynamic range image with the very bright background and the dark monkey. I pulled back the highlight and recovered the shadows a lot in post. Yep, you can see halo'ing if you look for it. PA240762 by Siftu, on Flickr o12-40 @40mm. I have no issues with it's sharpness. What do you think, am I wrong?
