p.1 #1 · p.1 #1 · Sony A7 24mm F2.8 Lens Comparison/shootout | |
This is something I'm doing for personal interest but hoping others may find useful too.
The lenses I'm comparing are:
1.Olympus OM Zuiko MC 24/2.8
2. X-Fujinon EBC 24/2.8
3. Canon FDn 24/2.8
4. Minolta MC VFC 24/2.8
5. Zeiss ZS 25/2.8
I'll keep comparisons in this this order throughout.
I was meaning to try a Minolta MD, but as my MC VFC is still unsold I'm using that instead, as in comparing it with an MD 24/2.8 a few years ago, they were as alike as two peas in a pod.
The X- Fujinon is an unknown, as there's virtually nothing about it on the web, however, I like its longer brother, the X-Fujinon EBC 100/2.8 so much that I tracked one down.
Obviously I've left some others major players out, like Nikkor Ai/AiS 24/2.8; Pentax SMC A 24/2.8 and Konica 24/2.8.
From web research, my general impression was that they were weaker than the above list. (Though there will always be those who disagree! )
Here they are: From the relatively tiny OM to the hefty ZS

Some Specifications first:
1. OM Zuiko MC 24/2.8.....8:7: 49mm ø; 185g; 59mm x 31mm; Focus > Aperture >
2. X-Fujinon EBC 24/2.8....9:8; 49mm ø; 195g; 62mm x 46mm; Focus > Aperture <
3. Canon FDn 28/2.8........10:9; 52mm ø; 240g; 63mm x 43mm; Focus < Aperture >
4. MC VFC 24/2.8..............9:7; 55mm ø; 325g; 67mm x 50mm; Focus < Aperture > (MD 9:7; 55mm ø; 275gMkIIa / 215g MkIIb; 65mm x 50mm)
5. Zeiss ZS 25/2.8............10:8; 58mm ø; 495g; 64mm x 90mm; Focus < Aperture <
The first test I carried out was for vignetting:
The picture is a screenshot of each lens, through the range. The OM, Fuji and MC have F16 as min F stop, The FD and ZS go down to F22, hence the extra image.

NB. The F16 exposure of the MC VFC is 2 stops less than F11. I suspect 11-16 is really F16 and 16 is F22. This is "sorted" on the MD version, which has F22.
I think these are fairly self explanatory. As I expected, the OM has a strong vignette which remains in the far corners throughout the series. Between F8-11, most of the vignettes become less defined on the other lenses.
I used the central area of my 27" iMac screen to take these, with the camera 9" from the screen and all lenses set to ∞
I checked with a light meter that the screen illumination was even over the photographed area.
Another impression was the very even colour temperatures across the aperture ranges and from lens to lens, I hadn't expected that! (These are SOOC, screenshot of Lr5)
