Photokina is underway so naturally there are a ton of lens related announcements. There’s some camera news too, but who cares… Cameras are outdated dated within a few months these days anyway. One of the most interesting announcements which I’ve been waiting weeks to discuss is the new 10.5mm from Voigtlander. Not only is this a nice wide focal length, it comes in at an impressive f/0.95. That’s fast for such a wide angle lens.
Everyone knows that bigger is better. Kinda… Larger sensors are often associated with lower noise levels and generally higher quality photos while smaller sensors are associated with lower data loads and higher transfer rates but noisier and generally lower quality images. It’s a trade off at this point in technology. What a lot of folks need to remember is that there is a fundamental difference between sensor size and sensor resolution. In particular when it comes to Red cameras and their wonky formats. A lot of people including Red staff will describe lens coverage in regards to a specific resolution such as “4K” or “5K”. That’s great since they pretty much own the names and if someone is asking if a lens covers 4K, they’re usually referring to a Red One or 5K on an Epic. But that’s where things get confusing.
I say database… But it’s really just a list trying to sound official.
So basically, RED has given the world a great deal of technology at a great price. But they also induced many a headache with different sensor sizes, resolutions, specs, and names. To make things a little easier, I’m compiling a list of lenses that pass through the shop and recording their image circle, or the diameter that they will cover without vignetting. This list will simply show you what the lenses are capable of. Feel free to comment on this post if you see any discrepancies or want a specific lens added. I want this to be as accurate as possible. Also note that the sensor/format sizes are generalized. There are a ton of different industry standards. There are several dozen formats that fall under 4 perf 35mm film alone.
