Hi, I got Olympus E-M1 with 12-40mm f/2.8 few days back and have been trying to work more and more on it. I am happy with this amazing and sharp lens except a small comparison with other superior lenses. I need to come too close to subject to get a pleasant bokeh. Another need is, to add a tele-zoom lens. I am not too much into wildlife, but whenever I go to any national park/forest, it will always bonus to capture reasonably clear and sharp photos of animals. I do not want to increase my lens collection more than 3 in total. I do not want to carry too much weight because I usually hike for few miles. I am not a pro, but a hobbyist who is slowly learning in this field. Mostly I love to shoot landscapes, nature, portrait+landscapes (my wife or sometimes me+wife, which I do on self-timer). There will be very less chances of using my camera inside room or in a small place. I read lot of posts to decide (and obviously get confused more ) and was able to select few options, but I can still change with some mix and match. I am in impression that I should have a standard zoom (which I have - 12-40mm), one tele-zoom and one sharp lens for portrait and low light situations. Considering that, I am thinking of :- 12-40mm + 35-100mm + 100-300mm = Will I miss prime lens and its bokeh here ? 12-40mm + 75mm or 45mm + 45-150mm = ??? 12-40mm + 75mm or 45mm + 75-300mm = It will let me for little more reach, I read that 75-300mm is still sharp till 250mm. Olympus 50-200mm f/2.8-3.5 ED = This will make overall kit heavier, not sure if it will benefit me that much. I am not considering new 40-150mm f/2.8 and 42.5mm f/1.2 due to their costs. If I need to choose prime, on what basis should I decide between 75mm and 45mm ? Few other posts say that, investing in 45mm is not worth as my 12-40mm should be very near to 45mm. Other says that 75mm is speciality lens, for portrait it is too close and for other purpose, it will be not be sufficient, though it is very sharp, but will hardly in use for a casual photographer. Confused .... Really seeking help to decide. Thanks in advance.
