SG-image 25mm f/1.8 (manual) : Samples At Different Apertures

This is a follow-up to my previous post on the SG Image 25mm f/1.8 manual lens.

In this post, I will show some pictures I have taken with this lens at different aperture settings, from wide open at f/1.8 to the smaller apertures at f/16.

This isn't going to be a laboratory lens test with charts and scientific measurements. It is simply a practical look at the images this little, (in my case heavily discounted) RM110 manual lens can produce. Perhaps it will also help someone else who, like me, is wondering just how good the SG Image 25mm f/1.8 really is.
