As I get to know more about me through photography, I have managed to explore with lenses and my appreciation for different focal lengths. Recently, I added the Voigtlander 21mm F/1.8 Ultron. I was looking at getting an ultra wide lens to my collection after purchasing the Sony FE 28mm F/2.0. The shots posted here are edited through Lightroom and lens correction has been added. I've always enjoyed the Voigtlander lenses. I have a 40mm F/1.4 and a 21mm F/4. My main shooter is the 40mm as the 21mm F/4 has issues with the A7R. The Ultron is a bit big. It is a fast lens and at 21mm it's bound to be. There is heft to the lens due to its construction. That's one thing I've enjoyed about Voigtlander lenses, they are well built with metal. The intro shot was taken with the Sony A7R @ ISO 500 / 6 Seconds / F22 I didn't want to get that trail of clouds most people get on their slow shutter shots. I wanted it to look like a moment frozen in time. I did edit the photo through Lightroom to brighten and add a little bit of sharpness. I also added the lens correction profile to photo.
Sony A7R + Voigtlander 21mm F/1.8 Ultron - ISO 640 - 1/30 When there's little to no light, the faster the lens, the more detail you can get under those scenarios. This photo was also editing through Lightroom.
Sony A7R + Voigtlander 21mm F/1.8 Ultron ISO 50 - 1/50 - 1:3 crop I can see this lens being a lens I can carry around most of the time due to its wide angle appeal and how convenient it can be when being with a group of friends. Cropping the photo to 1:3 it is still very detailed. It also speaks to the technology Sony uses on the A7R.
Sony A7R + Voigtlander 21mm F/1.8 Ultron ISO 800 - 1/25 - cropped - VSCO Filter I like the fact that this lens is really the one lens you can carry at a party or intimate event and catch everything with it due to its F/1.8. If you want to zoom in, you can get close to the subject or crop away. If anything the camera has 36 megapixels.
Sony A7R + Voigtlander 21mm F/1.8 Ultron ISO 1250 - 1/25 Most people who comment about this lens and its focal length said there's little separation between the in-front object and the background. As one can see from various shots, this lens has a nice bokeh. I need to play more with this lens and will make updates as needed. I think there might be some color issues around the corners when doing landscape shots. We'll see.
No Lens Correction - Voigtlander 21mm F/1.8 and the Sony A7R
Lens Correction added.
Here is a shot of the CA issues this lens has. It's been edited in Lightroom and the Lens Profile has been added to compensate for the CA. However, it still seems to be an issue with this lens.
In certain photos one can try to adjust vignette to 200, and it might work a bit, but you still have a bit of the purple/blue hue around the corners in certain shots.
The lens is just about perfect except for that issue. It is a great landscape and architecture lens. Walking the streets of Coconut Grove at midnight, the lens really shines at night. It's speed and low light capabilities make it an amazing lens. I was going to buy the Sony 21mm F/2.8 Ultra Wide Adapter (SEL075UWC), but at F/2.8 it is a bit slow for walking at night without a tripod.
I found the Voigtlander 21mm at 2.8 to be sharp except at the corner ends, which the Sony 28mm with the 21mm would just be sharp at the center.
