Maybe not so expert.. the exPert MC Auto 1:3.8 75-150mm

Cost: $17 (average market price unknown)


Very little to be find on this lens or lens brand. But does the lens brand hint to the quality of the lens?

In my honest and humble opinion, no, regrettable that is not the case. Although it is a decent looking lens with a built in hood, made from sturdy, mostly metal, materials, it does not feel that well made. The focus ring is smooth, but a little to loose. The aperture ring works well, but feels cheap. I prefer an aperture ring that also has some smoothness or resistance to it.

The lens is a push and pull type, but has no zoom creep (that's a good thing), but if you pull the lens to hard, it clicks into macro mode, being an annoyance while using it. The macro mode is also very limited, making it mostly useless as macro.

It was probably sharp enough for older film camera's, but on the Sony a6000, you can see that the lens is not able to equal the resolution of the sensor. This also made the lens hard to use with peak focusing, forcing the use of focus magnification. Due to vibration caused by the weight of the lens, that was difficult to do on a tripod.

The results are not that bad, just not as crispy as I would like. Might have to try again during daylight to see if that gives a different experience.

Not a good find, but maybe still useful for someone else with less demands.
