Folks, I can't afford Olympus' 300mm prime telephoto nor Panasonic's 100-400mm. Was thinking of buying Panasonic's Lumix G Vario 100-300mm F/4.0-5.6 OIS Lens as a compromise.
Anyone hear of any new lenses that would go up to 300mm that are being released soon? I want autofocus and I don't want to spend much more than $500-$600. That's why Pany's 100-300 seems like the best option, unless I'm missing something.
THANKS!
The 100-300mm is my most used M43 lens. Some advice:
This lens can give you great results IF you remember that you are using a very long lens, and treat it as such.
1) First, use good holding technique. Brace your body and arms well as you shoot. Small body motion contributes to less sharpness, even with the OIS (or IBIS) on.
2) Use either all electronic shutter or electronic first curtain shutter. This lens does much better with fewer camera body vibrations to cope with.
3) Try and stop down a bit if you can. Wide open it's a bit mushier, especially at the long end. If you can shoot at f7.1, you are at the optimal sharpness, esp at the long end. (It's pretty good even wide open down at 100mm).
4) Keep your shutter speed up. I have best results over 1/640s as a rule. That's not to say that I haven't been able to get shots as low as 1/30s hand held if I am sitting down and bracing myself well, but in normal usage, the faster the better.
5) Have patience while learning. It takes a little while to adjust your technique to get the most out of this lens. Once you do, you can do anything with it, but before you get to that point, you will have some fuzzy shots

.
6) Don't expect perfection on your first day out, as you gleefully hand-hold the setup and shoot everything you come across. Your keeper rate will be dreadful that day

.
7) Even the slightly softer shots from this lens will sharpen up very nicely in PP. Keep that in mind, and use RAW+JPG settings so you have more leeway in your files should you decide you have a shot that's a keeper, but needs a bit more work to make it just right.
8) And, last, but definitely not least, go out and ENJOY IT!
