This is a focus stacked dorsal view of on of my Brown Marmorated Stink Bugs. I use them quite often for experimenting for it helps me evaluate one session from another as a basis of standard.
This image was taken with a Mitakon 85mm f/2.8 1X to 5X macro lens set at a bit over 2X at f/4.0 with ISO max of 400 and auto shutter speed with constant diffused lighting.
https://zyoptics.net/product/mitakon-creator-25-85mm-f-2-8-1-5x-super-macro/Here's what I've learned with using this lens so far for those who may be interest in one:
1. It is very well build, buttery smooth to operate and at a more than fair price of $550. I give that 5-stars.
2. It provides a long working distance through all of the magnification ranges. This has advantages although it also has disadvantages due to the physics of light which causes the intensity to diminish with the square of the distance. Flash power or constant lighting will need to be adjusted to compensate for the distance from the light source to the subject. I give that 3-stars.
3. With a longer working distance the effective f/stop leads to diffraction so the sweet spot of the lens is in the f/4 to a max of f/5.6. I give that 2-stars when shooting subjects with hairs or fuzz.
4. The lens unfortunately has internal glare. Rats..! Looking into the back of the lens when holding it up to a light shows a lot of reflective glare and I have yet to find a way to work around it. I did flock the last 2-inches inside the lens although that is not the source of the glare. If anyone has ever used a helicoid extension tube they may understand what is happening. Images may tend to look milky or have haze. I give that 1-star.
5. The lens is rather compact for what it is and it is not very heavy so it feels proper on a small mirrorless camera. It is easy to hold and it has good balance regardless of what power it is extended to. I give that 5-stars.
6. The lens comes with a very nice LED ring light that is powered from an external source. It also comes with a Arca Swiss tripod mount which is also very well build and the lens feels securely mounted with no noticeable wobble, torque or orbiting. I give that 5-stars.
In summary, the Mitakon 85mm 1X to 5X macro lens has its place in my inventory of macro gear which I believe will make a good walk-around lens on my mirrorless cameras. With the lens mounted twin flash head macro flash rig it should be able to produce enough light to illuminate and to freeze the subject.
I have far better options for studio work that are less than $100 in total investment so better work will be produced by them. For special occasions I will use my D810 with the Nikon 200mm AF-ED f/4 although it is a beast to carry although hard to beat in what it can do.
I hope that some may find this review helpful and thanks in advance to all who view and for your comments, suggestions, question and critique.
