German company Meyer-Optik Goerlitz just announced the Nocturnus 75mm. F0.95 lens, which they claim is the fastest in the world. It will be available for Leica M, Sony E, and Fujifilm X.
Samsung Galaxy S9 teardown gives you a close look at its variable aperture
Recently released Samsung Galaxy S9 is the first smartphone that lets you change its aperture. This phone’s camera has caused a lot of interest, and it has knocked the Google Pixel 2 off the throne at DxO. In this video, JerryRigEverything tears down the Galaxy S9, so you can take a closer look at how its variable aperture works and what it looks like.
Oprema Jena revives Biotar 58mm f/2.0 lens with 17 aperture blades
After successfully funding a Kickstarter campaign for the resurrection of Biotar 75mm f/1.5, Oprema Jena is bringing back its “little brother,” Biotar 58mm f/2.0. The lens features unique bokeh, and it’s very sharp even at wide aperture. However, one of its most interesting features is certainly the record number of 17 aperture blades.
The new Atlanta Falcons stadium has an aperture roof
Football club Atlanta Falcons has a brand new stadium. The designers say it was inspired by Roman Pantheon, but as photographers, we found something else more interesting. The stadium’s retractable roof is inspired by camera aperture, and it opens and closes just like the aperture does.
Making sense of aperture, shutter speed and ISO with the exposure triangle
How important is exposure in photography? What are the components of exposure? What is the “Exposure Triangle”? These are the questions I will attempt to answer in this introductory post about ISO, Aperture and Shutter Speed – the components of achieving a properly exposed photo.
Understanding the purpose and value of exposure is a must for photographers, particularly beginners who are serious about developing their craft.
This animated video tells you everything you need to know about aperture
The aperture is one of the most difficult things for new photographers to wrap their head around. The number system seems confusing (smaller number, bigger hole), depth of field, how it affects exposure. It’s a lot to take in all at once.
This five minute animated video from YouTuber Apalapse goes over everything you ever needed to know about your camera lens’s aperture. It goes over some of the issues associated with picking which type of lenses you might want to buy, too.
This is how Canon’s f/0.95 Dream Lens performs on a Sony mirorless body
Do you use a DLSR lens on a mirrorless camera? Have you ever considered buying a “Dream Lens” for it? It’s pricey and relatively rare, so it’s worth thinking it through. But a member of Sonyalpharumors, Austrokiwi, allowed us to share his review. He bought a Canon 50mm F0.95 lens for his Sony A7rII. And this is how it performs:[Read More…]
What the heck is hyperfocal distance?
I often get the feeling that photography is talked and written about as if its practitioners have an innate knowledge of the terms involved. Any craft or profession comes with its own specialist language, but if you’re new to it—and even if you’re not—you can often feel overwhelmed by the terminology, let alone the technicalities of the medium. Thinking back ‘hyperfocal distance’ is one of the terms that most baffled me.
You will most likely hear ‘hyperfocal distance’ mentioned in relation to landscape photography. It describes a mathematically calculated sweet-spot that, when you focus there, maximises the depth-of-field across your scene. For, while you might believe that using a small aperture and focusing at infinity would do the job, it doesn’t.
What Actually Happens When You Stop Down a Lens
I got an email the other day that got me thinking. A guy simply asked “How far do I have to stop down a lens to get maximum performance. I’ve heard two stops from wide open. I’ve heard down to f/8. Which is correct?”
I asked him which lens he was referring to, and was he talking about the center point, corners, or overall. He didn’t realize that it mattered. He thought all lenses were the same and had this idea that eventually there was an aperture where the lens was maximally sharp and the corners were as sharp as the center. At this point, I realized there was no way I could tell him everything he needed to know in an email and I decided to write a blog post about it.
Everything You Need To Know About Depth of Focus and Lens Equivalency
After learning about the history and science of lenses, and gaining some knowledge about the properties of modern lenses, it’s time to take a deeper look at depths of field and how it’s affected by sensor size.
Kick back as John Hess of Filmmaker IQ takes us on a 17-minute long journey through the optics, the terms and the calculations that will help you understand how depth of field works once and for all.
