5D Mk IV – EF 100mm Macro – Einstein 640W Strobe – Kenko Extension Tubes – 1/125, f/29, ISO 100

Early birthday present arrived today – see last photo below. This little bundle will open up a world of possibilities for future photos. 50mm f/1.2L lens, an assortment of variable neutral density filters, extension tubes for macro work, and a super mag slider for even more close up macro work.

I took the extension tubes and the slider for a quick ride this afternoon. The Photo of the day was made using a 36mm extension tube with the slider assisting in focusing. I look forward to taking the setup out in the sunshine – that should make focusing even easier.

The second photo of the watch was made using three extension tubes – a 12mm, a 20mm, and the 36mm. I was about 2 inches from the watch.

Extension tubes are designed to enable a lens to focus closer than its normal minimum focusing distance. They have the effect of magnifying your subject and are useful for macro photography, allowing you to convert almost any lens into a macro lens while maintaining its original optical quality.

The extension tubes have no optics. They are mounted between the camera body and lens to create more distance between the lens and sensor plane. By moving the lens farther away from the sensor in the camera, the lens is forced to focus much closer than normal. The greater the length of the extension tube, the closer the lens can focus.

It’s worthy to note that neither of the watch photos were cropped. And, yes, I know the date is incorrect on the watch – the battery is dead.
