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. Long Exposure - HDR Long Exposure - HDR Long Exposure - HDR Edited in LR @F/1.8 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. LR + a bit of Sharpening 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. This lens will be added to my walk around bag, which consists of the Voigtlander 40mm F/1.4, Sony 28mm F/2.0, Contax Zeiss 90mm F/2.8, Sony 28-70mm kit lens, and the Neewer NW-610II Mini LCD Display On-camera Flash. When I tried the 21mm on the Sony A7Rii, it had no issues.
