What’s the Fastest Lens Theoretically Possible? And What Would it Look Like?

We've told you about some pretty fast lenses in the past -- from the legendary Zeiss 50mm f/0.7 lenses made for NASA and used by Stanley Kubrick to film a candle light scene, to X-Ray lenses that you can try to Frankenstein onto your camera body for some strange soft-focus results.

But what is the fastest lens that is theoretically possible? And what would that lens look like? Matt Granger answers those exact questions in the interesting technical video above.

Adobe Just Released a Simple and Free Aperture to Lightroom Migration Plugin

If you've been looking to migrate your Aperture library over to Lightroom ever since the official announcement of Aperture's demise, you've had to be content with manually doing it or using one of the unofficial tools that had already been released. But that is no longer the case.

Earlier today, Adobe officially released its own tool: a free Lightroom plugin that will allow you to import your entire Aperture (or iPhoto) library, metadata and all, quickly and easily.

Understanding Aperture: Why Shooting Wide Open Isn’t Always the Best Choice

When you drop hundreds or thousands of dollars on a new piece of fast glass, it’s natural to want to shoot it wide-open until the focusing ring falls off. But, the idea that for all portraits you want to be wide open and for all landscapes you want to be stopped down isn’t true. Here to explain in the above video is photographer Matt Granger.

Free Aperture to Lightroom Migration Tool is in Open Beta

The announcement that Apple is discontinuing Aperture has left many users wondering how they’re supposed to properly transfer their soon-to-be irrelevant file structure over to Adobe's Lightroom.

Neither Adobe nor Apple have yet released an official means to do so (at least not yet), and so software developer Adrian Grah took it into his own hands and created Aperture Exporter: a free utility that automates the process of moving from Aperture to Lightroom 5.

LensRentals Celebrates Independence Day with Some Gratuitous Lens Mutilation

A couple of weeks ago I got an email asking if we would be willing to take some lenses, remove the electronics, fix the aperture wide-open, and permanently lock them at infinity focus. It seems the person who needed this done was having trouble finding a legitimate repair shop or service center that was willing to do it.

Well, illegitimate is our specialty, so I started negotiations about just how exorbitant a fee we would charge for this work. We quickly arrived at a fair price (no money, but we get to take pictures) and yesterday received brand new copies of the Canon 100mm f/2 and Sigma 35mm f/1.4 Art to work on. If you’re the kind of person who slows down to view car wrecks or spent $200 on fireworks for the 4th of July holiday, you might like this.

Breaking: Apple Officially Kills Off Aperture

The day has come. We all felt it in our bones, but today it has been confirmed by the guys in Cupertino: Apple has stopped development of Aperture, its professional-level photo organization and editing software.

New Chemical Iris Technology May Change the Way Smartphone Apertures Work

As smartphones have gotten smaller and smaller, the need for the cameras inside of them to shrink has become more pressing. One area where there's a lot of room for improvement is in the traditional mechanical aperture.

As we begin to hit the physical limit of the overlapping blades, researchers at the University of Kaiserslautern have designed an exciting new ‘micro iris’ that uses small chemical rings rather than a physical blades, dramatically shrinking the size of the aperture components in the camera.

6 Things You Don’t Know About Apertures, But Probably Should

One of the first things that we learn when we start taking photographs seriously is that ‘aperture’, the size of the hole in the lens through which light passes, controls depth of field.

A large aperture creates shallow depth of field while a narrow one creates wide depth of field. But there’s a little more to aperture than that, let’s take a closer look at this most fundamental photographic control.

Back to Basics: Short Walkthrough Covers the Exposure Triangle for Beginners

When you're first learning the basics of photography, one of the first things you find out about after dropping out of 'auto' is the exposure triangle.

Consisting of shutter speed, aperture, and ISO, the exposure triangle is a system that takes into account each of those variables, making exposure adjustments a breeze when you need to change one of the variables for a particular situation (say, freezing motion or achieving a shallow depth of field).

Tutorial: Short, Sweet Workflow for Editing Street Photography in Lightroom 5

When it comes to street photography, much of the aesthetic appeal is the limited editing that usually takes place (or doesn’t take place, I guess), leaving the story and subject the focus of the image instead of creative editing. But that's not to say that editing should be left out of the equation or completely disregarded.

If you're wondering where that line should sit, this tutorial by Swiss street photographer Thomas Leuthard shows you what he does when he imports his street photos into Lightroom 5.

A Concise Explanation of How Crop Factor Affects Both Focal Length AND Aperture

Editor's Note: Due to some issues with the camera, this video is very shaky at times. It didn't bother us much, but if you're easily distracted this video might annoy more than it educates you. You've been warned.

If you're just getting into the world of cameras and lenses, the term "crop factor" and phrases like "this is a 35mm equivalent lens" might still confuse you. Well, that shouldn't be the case much longer.

The video above offers a clear, concise and simple explanation of crop factor that will hopefully clear all of this up and equip you with some important knowledge that will come in handy the next time you're shopping for a lens or crop sensor body.

Canon Shows Off the Inner Workings of Its Lenses in Cool CES Demos

Unfortunately, what with major changes at the helm and making sure that we hit 2014 running, we weren't able to make it to Vegas for CES this year. And I say unfortunately because, not only does it mean we'll have to wait a minute to get hands on with some of the new releases, but it also meant missing cool demonstrations like the ones you see above.

Sigma May Be Building a Groundbreaking 24-70mm f/2 Lens for Full Frame Cameras

Sigma has been on a tear as of late. Since late 2012, the company has put out a highly regarded 35mm f/1.4 lens, a novel USB dock that lets you calibrate lenses at home, and a revolutionary 18-35mm lens with a constant f/1.8 aperture (shown above).

It appears Sigma is only just getting warmed up: new rumors suggest that Sigma may be building a 24-70mm zoom lens for full frame cameras that boasts a constant f/2.0 aperture.

Sigma’s Game-Changing 18-35mm f/1.8 Zoom Lens to Cost Just $799

Sigma shook up the camera world back in April by announcing its new 18-35mm f/1.8 DC HSM lens -- the world's first zoom lens with a fixed maximum aperture of f/1.8. It turns out the revolutionary lens will have a revolutionary price tag as well: the company announced today that the lens will cost just $799.

Overcoming My Photo Entekaphobia: The Fear of Shooting at f/11

Entekaphobia is fear of the number 11. I’m a resolution fanatic. I test every new lens for resolution. For personal use, I’ll choose the lens with higher resolution over the one with creamy bokeh every time. When choosing a camera, I have a (yes, I’m ashamed to admit it, but it’s true) strong tendency to want the most megapixels. I’m a resoholic.

Being a resoholic, I’ve always been somewhat fanatical about apertures. Whenever possible I shoot with the lens stopped down at least one stop to wring the maximum sharpness out of my lens. But I’m always careful not to stop down too far because I was taught, soon after I picked up a camera, that if you stopped down too far the dreaded diffraction softening would kick in.

Some Nikon D600 DSLRs Not Closing to the Apertures They’re Supposed To

A little earlier today, we reported on how Sohail Mamdani of BorrowLenses had discovered that one particular Nikon D600 he was testing was consistently overexposing photographs by two stops. After searching long and hard for the cause, he stumbled upon the culprit: the D600 wasn't closing the aperture blades to the correct opening size.

Apple Job Postings Hint at Mobile Version of Aperture

Rounding out a day packed with Apple announcements and general excitement at the WWDC 2012, here's one final Apple tidbit coming from rumor site Apple Insider. According to them, recent job postings at Apple hint at the possibility of an Aperture mobile app coming in the near future. After receiving a tip from an anonymous user, Apple Insider found that the Aperture team is looking to fill quite a few manager and developer positions, many of which require experience developing on the iOS platform in one form or another.
