Introduction

From time to time, TTArtisan creates unconventional but very interesting lenses not typically found in other lens manufacturers’ offerings. (e.g. the 100/2.8 bubble bokeh, or the 100mm 2x macro Tilt/Shift). This time they have come up with a telephoto lens. A light and compact full-frame mirror lens with an unconventional focal length of 250mm. On an APS-C camera it has an equialent focal length of 375mm, which touches the realm of super telephoto lenses. Let’s have a look!
I tested this lens on a Nikon Z 7II mirrorless camera, which has a 46Mp full-frame sensor. Sample images were taken in both FX (full-frame) and DX (APS-C) formats. Whenever the image was captured in DX format, I noted it in the caption.
