Re: Some of my first photos with A6300

Craig,

I did some test topside with and without the diopter. 3 shots of a ruler each at f16, f18 and f20. Distance in each case the MFD of the diopter and the MFD of the lens.

Without diopter it produced an image 42mm wide (0.56x magnification) and without, 93mm (0.25x).

Without the diopter I can notice some softness in extremes. That' s due to lens. With the diopter this same softness seems more pronounced but in can be both the magnification (less area in central focused) or and addition of the diopter itself.

When the image without the diopter is cropped to match the 42 mm wide (about 2700 px wide instead of original 6000)  the softness in extremes disappear, of course.

Theres is some noticeable loss of light with diopter but I can not take that as a fact because I think the main reason was the flash ("tied" to the focus lamp on top of camera) being obstructed by the short port. Diopter are said no to cause important light loss.

And maybe this less light with diopter could cause the shot to be softer.

What do you think?

Regards
