Both of them are good value and capable of good results.

I use the EM-1 and EM-5 with the 75-300mk2 and its very fast focusing with excellent sharpness and resolution wide open, even at 300mm.

I have read (but can't confirm from experience) that the construction of the 100-300 (iris?) slows down the focus speed, maybe someone else with experience can clarify that?

(Early on I made the mistake of using the 75-300 with the aperture closed down to f8+, not a good idea as diffraction softening reduces the sharpness visibly)

I use an EM-5 with 100-300 and would say that the focusing speed is fine.....the problem with the aperture actuating mechanism is that it can't keep up when using high speed drive (8 fps)..at 4/5 fps no problem.

The main point to consider is what body you're using.......the 75-300 doesn't have IS so using it with a Panasonic body is not so good.

thanks for the clarification Roger Smile

thanks guys. i'm using a pm-1 body so the lack of IS is not an issue.

Sounds as if your best bet would be the 75-300......it's lighter, and you get more at the wide end.

I have used a number of the Panasonic cameras and am now enjoying the GX7. I took the three below this morning using the 100-300 in unusually glorious Aberdeen sunshine. The building is the the Aberdeen University library by the way. 100mm, 205mm and 300mm. all at f/8. RAW converted in DxO 9. I used to have to carry a Canon 100-400 but can't any more. The lens is worth buying in my opinion.

very good IQ, you all seem to use cameras with a evf. in your opinions would a evf be an advisable add-on or not?

The main advantage of the Pansonic over the Olympus is the extra speed. On lenses like this you want to gather as much light as possible.

I did a review of it here .

It rather depends on what you want to shoot and your own preferences.

Having come across from using a DSLR to shoot my birds, sport and natural history images I would not be able to work without an EVF, likewise trying to focus a long lens whilst looking at the LCD rear screen


others seem to manage OK (I'm guessing they have probably switched from consumer level digital cameras without EVF so have developed techniques that suit them best? )

If you want to see some images shot using the 75-300 + my various blogs on the subject have a look at my site here loads of pics and words

i prefer a evf over the lcd Brian. i started my photo hobby with a canon s5is then a sx20is so i grew accustom to the evf. with my failing sight i feel more comfortable with a evf. i can pick up the evf2 used with warranty here in the U S for$160-$170 so i will be purchasing one. i may do some macro with oly legacy lens and i'm sure it will be invaluable in that respect
