Default 7-14mm f2.8 M. Zuiko at f2.8 and f4

Working with this lens in bright light where f5.6 or smaller and ISO 200 are a good combination, image sharpness across the frame is fine, but what about lower light where you need to be opening up to f4 or even f2.8? Well, you will get some softness on the edges, especially if you focus closer to infinity and have objects both near the edges and up close.

But it's definitely not a deal breaker if you take some precautions, like making sure you set the focus up closer to the front of the image. I try to stay within the front 1/3rd of the frame when shooting with this lens at the two largest apertures. If the main subject is beyond that between 7-9mm anyway, it's usually too small to make all that much of an impact.

It's also important to remember it's not just a 7mm lens. My 12-40 also can't do 8mm, 9mm, 10mm and 11mm and those are all excellent with this lens.

These were captured this morning in overcast conditions at ISO 400 with the E-M1.

f4 and 10mm..

And here's a near to far composition, 10mm shot at f5.6, focus set on the second planter along the rails.

Things are just starting to turn around here. I looked last year and I was shooting images of trees at their peak the last week of November.

Those are great shots Greg, that lens looks to be a keeper for sure.
