If you are looking for an even greater image scale, you can introduce a teleconverter, which effectively doubles the magnification of the lens, depending on the degree of magnification. The only caveat to this

Depth-of-field calculations are flawed. They calculate the largest aperture that will give barely passable sharpness. They do not calculate the aperture which will give you the sharpest photo, just the bare minimum.Depth-of-field charts and scales came from an era where film was very slow and...

If you know the barlow's focal length then there are formulas that can tell you the magnification and spacing that is needed. Then, it isn't too difficult to determine what change there will be in the focus position. However, most manufacturers don't state the focal length of the barlow...
If you’re focusing at high magnifications (e.g., you’re using amacro lens), then you’ll struggle to lock focus. Any movement will shake off moisture and may even break the webs. So you must take care to shootonlyon the stillest of days. Check your local weather forecast, and ai...
Oh, and one last note. You’ll notice that nowhere in my testing do I say how to calculate “is my copy sharp”. It’s a meaningless calculation unless you have dozens of copies of the same lens like we do and are using some standard measurement of sharpness. I know, for example th...
