In a bit of a quandry
I just got a 100-300OIS to go along with the 2 lens kit G3. I assumed the 100-300 would give me some things I both wanted and needed over the 45-200, which frankly I love and used a LOT when I had mft before. Frankly...the 45-200 is considerably sharper even all the way out at the tele end. I found the other night when shooting in daylight that only perhaps as much as 20% of the handheld shots I was taking were truly sharp. I can't live with that. I also HATE bringing monopods and tripods to drag around. I'm on the move typically and prefer smaller the better. So perhaps I jumped on this too soon. It's going back for some more thought on the subject. I seriously think I would get a LOT more use out of the 14mm f2.5 to keep the camera tiny and useful for outdoors. Especially indoors with people and such. I already am getting the 20mm f1.7 next week anyway as that's a "no brainer" lens. perhaps I should just settle on the 45-200 being my long lens and shore up the wider end with those 2 pancakes. Any opinions? I don't do birds and haven't even had the need for much wildlife yet. It's the fact that the 100-300 requires a very steady hand or tripod or monopod for best results, and I'm a somewhat shaky shooter

As the lens focal length increases, stability becomes more of an issue. The rule of thumb for hand held shots is Min. Shutter Speed = 1/lens focal length (in 35 mm format).
So your 100 - 300 is actually equal to 200 - 600 mm (35 mm)
At the full telephoto position (600 mm equiv) that means that to get a good steady shot (hand held) your shutter speed needs to be 1/600th sec. Kick in the OIS and that gives you a 2EV advantage, so you should be able to go down to 1/150 th sec (hand held).
Any slower and you are very likely to see some jitter induced blur. I use a lightweight monopod - easy to carry and inexpensive. Better yet, build
this poor mans image stabilizer. I have one in my camera bag ant it works great!

I have a pretty steady hand, and with the OIS engaged, I still couldn't consistently hand hold this lens at full tele and 1/150th second. For the most part, I would try to keep the shutter speed up around 1/500s with the OIS on and had consistently sharp results with those settings. Of course, that means using higher ISO values, but the G3 can handle it.

I know all too well about what is required in shutter speeds typically to keep things sharp. I just wanted a lens I wouldn't have to be concerned about regarding it's consistency in field use. 20% keepers are not acceptable. Honestly I'm used to more like 90+%. The 45-200 delivers 100% so I'm spoiled  I'll give it another try tonight before I pack it up to go back. I rather like the idea of having the 14mm f2.5 and a 20mm f1.7 at my disposal. I'd use those a LOT more often to be sure. I'll keep you posted on my decision and why.

Dcisive,
FWIMBW, please consider that any lens, but most assurredly a long focal length lens is going to perform in a highly variant manner. There are many too many variables between your sensor and your object that are changed, magnified or generally affected by a long focal length lens for such a lens to offer consistency that will satisfy a field photographer. I am not talking down to you, I am expressing fact and the results of probably 10,000 to 50,000 photos taken through lenses having focal lengths in the 200mm to 800mm range and costing many thousands of dollars. Even these expensive lenses shot on tripods, one or two, gyro stabilizers, bean bags, King Cobraw, Wimberley brackets, etc., etc., etc. do not come with a guarantee of consistency. Use a long lens in the morning light versus the twilight and your results may well be inconsistent. Shoot 15 degrees to the sun versus 180 degrees to the sun and your results are predictably inconsistent.
I have seen mediocre results with the 100 to 300mm lens, which I do own and use. I have seen other results that are positively wonderful. Beauty is in the eyes of the beholder and consistency is either in the hands of the user, but not in the lens, in my opinion and experience.
Best regards,
Tom

For me, 45-100mm is the most useful range, and I rarely want anything longer than 200mm. For those rare occasions, I bring along a TCON-17 1.7x lens.
I do wish that the 45-200 were a bit wider and a bit faster, e.g. a 35-100 at f3.5 or f4 constant, but then it would probably be larger and heavier!

Tom, those are wise words. I've been at this for a good number of years and had lots of pro gear as well. I typically have not however, used lenses beyond stock 400mm lengths (regardless of what the crop magnification might have done for it). So I do understand what you're saying and agree 100%. With that said I went out once again tonight just to make sure of my decision. I shot at 300mm all the way out, typically f8. Even tried f11 on a few. The shutter speeds in aperture priority mode (what I prefer to shoot in) was typically 1/500th to 1/1000th sec. I was handholding and doing the best I could to make sure things were stable before I took the shot. Out of 14 shots 3 were outstanding and the rest were pretty much not acceptable in the end for enlargement. I have no interest in that result. My kit 45-200OIS is ironically virtually 100% consistent regardless of f stop or light quality. It just nails it every time at 100% on the screen, and I LIKE that. I can crop and get the same perspective as what I shot with the 100-300 on a G3, so to me it's not staying. I'll most certainly get a 20mm f1.7 pancake and perhaps might also get the 14mm f2.5 for indoor and landscape stuff. The kit 14-42 isn't very nice. I may appeal to the dealer since it's only been a few days of ownership, to get another copy to try. I like having the kit focal length for good light outdoors walking around, but in this case heck. I paid the money the least I should have is a decent working copy. So that's the route I'm going. I'll stick with the 45-200 for my long lens. It always did serve we well before.

dcisive,
I am happy for you and for others who may learn from and/or share your experience. What you found out is a replicate of my experience.
My wife and I shot serious wildlife for many years. We used the top Nikon glass in 300mm, 400mm, 500mm, 600m and 800mm. We have shot on most available mounts, windoe brackets, ground brackets, bean bags and tripods (wooden, aluminum and carbon fiber composite),Most of this shooting was without Nikon VR. If we used a very sturdy tripod and made certain the lens was not a lever in the wind, our shooting percentage approached the same with short focal length hand held lenses. By the way, there is a fair amount of difference in performance among lens copies. Nikon actually replace a 200 to 400mm lens we bought and I can honestly tell you that the old Nikon 500mm P lens was an extremely mediocre lens.
We learbed our lesson one day when we tried to shoot a small Dahl sheep from urnagin Arm looking up toward Girdwood, Alaska. We knew of the sheep and we had tried the shot in previous weather that was relatively good. This day was cold, rainy and the wind was strong and puffy. We placed a 600mm f/r under rain gear on two substantial Gitzo tripods. I literall hung on the assembly toward the rear tripod while my wife took the shot in gosh awful grey flat lighting with a remote trigger. The results were totally unremarkable, the picture was an absolute nothing, but it was perfectly sharp and posessed no apparent motion blur. Suffice it to say, this was a "LESSON LEARNED" experience.
As for the 100 -300mm, I like my lens. I do not hand hold this as I do not feel that I am sufficiently steady. I actually use an oversized older Gitzo graphite composite with a Kirk QR-topped ball head. Most folks will tell you this is too much. My experience suggests differently. I look at this lens as being in a class of its own. Where else are you going to get a 200mm to 600 mm lens that fits in your hands and in many larger pockets and does not drain your life's savings? Yes, I have become very impressed with Panasonic gear overall, lenses in specific and the progress Panasonic has made in the past 10 years.
I am truly happy that I helped you and hopefully others.
Best regards,
Tom

This thread makes me wonder about the possibility of something like Olympus' 1.4x extender, but in m4/3rds...
