Where the four-thirds 70-300 has the advantage over the micro 75-300 is the close focus range. The Micro 75-300 focuses down to 2.96 feet at 75mm and 75mm only. Zoom it to 76mm and beyond and the close focus distance extends to 5 feet, making dedicated extension tubes a necessity for getting in really close.

The maximum aperture at 300mm is a push, there's just not that much of a difference between f5.6 and f6.7, especially for the extra small size gain of the micro model, and one should try the 75-300mm on a tripod at 300. I think I can hold lenses pretty darn steady but 300mm off a tripod with IS turned off, that lens is very sharp. Handheld, it can be frustrating sometimes, which is why I often do not carry it. Back in my film days the longest lens I ever used was a 180mm f2.8 Nikkor, and the 35-100 Panasonic goes longer than that (180mm on 35mm film body vs. 100 in micro four-thirds).

I think I'll always have a long lens in my bag if I can, when shooting wildlife you rarely wish you had brought the shorter lens.

I love my 70-300, it took some getting used to on the E-PL2 but on the E-M1 it just works very well. Given the current low price of the 70-300 refurbished I'd probably replace it with another if it crapped out. I think I could probably live with the 75-300's slower aperture now that I have better high ISO performance, but the Panny 100-300 sure is tempting. I'm really hopeful the 300mm f4 pro lens comes out at a similar price to the 12-40 as it will be on my buy list, even if it is big nothing beats a bright long prime.

Hey Fred: you don't need to buy another 70-300 lens. Olympus will repair it for a flat fee of $95.

That is much cheaper than buying a used one. Here is the link for repair of the 70-300:

The 300mm f4 may indeed be the more economical of the three soon-to-be-available pro series. I'm expecting the 40-150mm f2.8 to be in the $1,400-$1,500 range and the 7-14mm f2.8 should be close to the $1,700 to $1,800 the 7-14mm f4 four-thirds Zuiko costs.

Interesting. There are so many "new" features that I haven't even started to scratch yet . . .

Yeah, this digital TC option has been available for a little while. I remember it at least as far back as the E-P3 but it was not until the E-M5 and the better 16MP sensors that it really was a viable option if you wanted a result up to snuff quality-wise.

Panasonic does it differently, cropping the sensor down with their version of the same thing and leaves the resolution at the native amount with no re-sizing, so it is similar to just cropping in post processing, except the cropping is done in-camera before you shoot so AF and metering are done over just the area being used, which in theory should produce a better result than capturing with the entire sensor area and cropping after the fact.

Your M1 may already be up to date, and I've heard AF is already good on the M1. But just in case, I thought I'd mention the last firmware version 1.4 improves AF on the M1 when using full 4/3 lenses.

Yeah after a week or two I checked and found my E-M1 was surprisingly not updated from Olympus. A few days later I went on an update spree, finding all my lenses needed updates as well. The performance before was good and it definitely improved, the camera is just a real dream to use now with the 4/3 lenses.

A few of my lens updates were only for performance on certain cameras, so i didn't really bother with a lot of them.

My EM-10 update was the one that let you set an antishock of "0" which apparently helps a lot (though you couldn't prove it by me).

The -0- antishock works well, but only at shutter speeds of 1/320 and below. From 1/400 up it's not even used. The speeds where it's helped me are in the 1/125 to 1/200 second range. The last E-M5 update added the small AF boxes and ISO 100, but no zero antishock, which was a little disappointing, although I don't use that body all that much these days.
