| p.1 #7 · p.1 #7 · Voigtlander 15/4.5 III E-mount Rolling review |
I just checked the test images and...I have good and bad news.
Here are my initial impressions:
* The new 15/4.5III E-mount looks and acts like a native lens. For those who already own a Loxia lens, communication with the camera is very similar. Instant magnification when rotating the focusing ring, correct FL for IBIS, corrections in-camera (CA, Vignetting, Distortion), etc..
* It's still very compact. It weights about the same as the M-mount version with the Voigtlander E-mount adapter. The hood is a little shorter than the original M-mount hood.
* Aperture ring can be declicked but it's easier than what Zeiss did with the Loxia line. Just lift the declicking ring and rotate it clockwise. The aperture is now declicked. Genius.
* There is no difference in vignetting, resolution, contrast and distortion. It's basically the exact same optics with the E-mount.
* LaCA is still present towards the corners. It's apparent at f/4.5 and does not get better when stopping down the aperture. Can be automatically removed in-camera or with Lightroom's custom profile for this lens.
* Vignetting is on the high side at f/4.5 and does improve much when stopping down the aperture. It can reduced in-camera or using the Lightroom's profile.
* The E-mount version has its focusing ring much closer to the mount. On the A7RII, this is actually not ideal ergonomics. It's somewhat awkward to turn the focusing ring due to the A7RII's grip deeper grip. My left finger does not have enough clearance to fully turn. (It keeps rubbing against my right fingers on the grip)
Since there is absolutely no optical difference between the E-mount and M-mount versions, I decided to skip posting side-by-side crops (they look identical) and instead focus on comparing the E-mount the SLR adapted Distagon 15/2.8 ZE.
Some of you may be disappointed with the below 'extreme edge' crop but keep in mind that very few ultra wides perform well in this area. Outside from the 10% of the frame edge, the Voigtlander improves astronomically. Extreme edges are also overrated and may not show up in your images most of the time.
UPDATE: Ignore the extreme crops. My E-mount is not a good copy. Read this:
Voigtlander (top) versus Distagon (bottom)
All images taken at f/8
Sharpening and WB (daylight) the same for all comparisons.
No other exposure changes or profiles applied
CENTER: Voigtlander (top) versus Distagon (bottom)
