The 1st two taken (on an E620) with EC14 & 50-200 lens is a good combination, but the next two with EC14 & 70-300 lens is not going give you a great result.

The 70-300 alone is soft at F/5.6. You have to close the aperture with 1 stop (F/8.0) to get decent results.

When attaching EC-14, you have to add 1 stop, so you have to stop down the aperture to F/11 to get reasonable sharp photos.

As you shoot wide open (F/7.9) it is normal to get soft pics.

Thanks for the reply. Because the shutter speed becomes a little slow at that aperture (or high ISO), I prefer to not adding anything to that lens.
