ok so here i go again, still confused and not been able to have a definitive reason to buy the Oly ZD 50-200 SWD. i want to try wildlife/birding/ sports photography. i havent shot any of these since i dont own a tele lens. i am almost convinced to buy the Oly ZD 50-200 SWD as it is really optically superb and the fastest among my choices. the few reasons though that prevents me from placing the order, and it's kinda big for me. i don't like the size of its hood. really awkward looking and massive, if only the non-swd version hood will fit to this. second, i know it will fell short in AF speed compared to the native mft tele lenses. i tend to say that is a bearable con but i guess soon i will find it slow as my photography advances. these are the only reason i still cannot decide. i'm low on budget as this will be my first tele lens (this will be my training ground) i will keep my budget up to 500USD only. so the MZD 40-150 2.8 is not an option here. i have the Pana Lumix 100-300 4.0-5.6 and the Oly 75-300 II as the runner ups. it will solve the issue on bulkiness and AF speed but a few drawbacks, slower than the ZD 50-200 SWD,no tripod collar option and optically inferior to the ZD 50-200 SWD. i favor the Pana Lumix 100-300 4.0-5.6 over the Oly 75-300 II as i thought it is more ergonomically well balanced to handle and slightly faster, but as per reviews/lab tests. the Oly 75-300 II is sharper. again im confused. i would like to ask your opinions and recommendations. especially to those who owns the combo. please help me out. i will make sure i will not regret this decision.
