Meike 7.5mm f/2.8 Fish-eye - Review / Test Report - Analysis
Lens Reviews - Sony Alpha/NEX (APS-C)


Fish-eye lenses are fish-eye lenses so it doesn't make much sense to provide numeric figures here. Our usual distortion test-charts looks like this here:

And for the fun of it - when trying to place the edges of the grid into the image corners the effect looks like this - taken from a 10cm distance or so.


Sorry, no vignetting figures this time - there's no reliable way for us to measure this with such a lens. However, the issue is moderate based on the sample images we took.

MTF (resolution)

The resolution characteristic of the Meike 7.5mm f/2.8 Fisheye is quite astounding really. While it is basically impossible to take lab readings for the corner performance, the lens provided tack sharp results in the image center, and the borders are already very good at f/2.8 and great at f/4. In real life - see our sample image section - the corners are also pretty impressive. Diffraction shows some impact from f/11 onward, so it's best to stick to medium aperture settings if possible.

The centering quality of the tested sample was good.

Please note that the MTF results are not directly comparable across the different systems!

Below is a simplified summary of the formal findings. The chart shows line widths per picture height (LW/PH) can be taken as a measure of sharpness. If you want to know more about the MTF50 figures you may check out the corresponding Imatest Explanations

Chromatic Aberrations (CAs)

You may think lateral CAs have to be bad on such an affordable lens, but this isn't the case here. With an average CA pixel width of around 1px at the image borders, you can spot this at times, but it's not dramatic. The issue increases somewhat in the corners, though.


Flare may be the weakest aspect of the Meike 7.5mm f/2.8 Fisheye. While Meike claims that this lens is multi-coated, it still struggles with strong light sources. The effect can be interesting at times, though - like these "traveling" ghostings below. There's also some loss of contrast but it's not extreme.

And yes, the lens can also produce sun stars.
