    I have panasonic cameras. I have a G6 and a GM1. I am looking to add a long zoom to my lens collection. It's seems my choices are 75-300 Oly and the 100-300 Pany.

    I realize that the Pany has ois and my cams do not have ibis. Therefore I am leaning towards Pany.

    However, it is not out of the question that I may someday get a body with ibis.

    I plan on using the 300mm for wildlife, birds etc. I don't plan on using it for sports, etc. I also realize putting it in the gm1 will not enhance the portability of the camera. Lol.

    Please help me with me pros and cons. Also, are there other choices ot there?

    I did a ton of research into this same thing a while back.

    Bottom line - if you have good copies of each, both are pretty indistinguishable in IQ.

    The deciding factors for me were that I Iiked having the wider 75 and I did not need the OIS. Also, the Oly as cheaper.

    If you have cameras now without IBIS, then having he lens with it in, will be a necessity. At 300mm, if you need to hand hold, the stabilization will be very helpful.

    The 100-300 works surprisingly well on the GM1 - the weight of the combination (at least with a grip) is directly under the zoom ring, so you can hold it fairly well with the left hand and fire and steady with the right. You'll definitely want the stabilization switched on though, and use faster shutter speeds than you think. I don't think the 75-300 is viable for handholding on a non-stabiized body, at least not at the longer lengths...

    combination.

    Agreed, because your FOV at 300mm is like trying to hand hold a 600mm. You definitely want that stabilization!

    I have an E-M10 and the Panasonic 100-300mm; I actually find at 300mm handheld, the OIS is more stable than IBIS. Either way, it's a fantastic lens...the f/4-5.6 swayed me to go for the Panasonic over the Olympus lens btw.

    I've shot in the past with the 100-300 on an EPM1. Now I have a GX7. You simply hold the lens. It's no big deal.

    Without IS, when shooting at 300mm, you will need to maintain 1/600 or more shutter speed when you are at f/5.6 (or with the 75-300, I think the f/stop is f/6.7). Additionally, the P100-300 has great close-up capabilities. I shoot a lot of flowers with it. You really need higher than 1/600 for that kind of work. The IS is really helpful.

    On an IQ basis -- neither is a bokeh king, but I thought the P100-300 had better bokeh (less nervous), based on online samples that I viewed, vs. the 75-300. I never used the 75-300, so that's only based upon on-line research. Used, you should be able to get a P100-300 in the States for $400 or sometimes a little less. That's what I see the 75-300 going for used, too, so prices are pretty much the same now (when the O75-300 was first launched in 2010, it was much more expensive than the P100-300 IIRC, but it didn't sell at that price level, so they had to drop to the Panny price point)

    I tested the Oly 70-300 before I bought the Panny 100-300. The Panny's faster aperture made a big difference to me. It allows faster shutter speeds. Plus the in-lens OIS seems more effective than IBIS at that kind of focal length, IMHO.
