At some point in the history of photography, a convention was born to describe lenses in comparison to a 35 mm film camera. We’re going to have to get nerdy to explain why this doesn’t work. iPhone 13 Pro at 77mm → Zero Items Matched Why Doesn’t This Work? You are probably expecting me to say, “And Bob’s your uncle, we now have a smart album of photos taken with the telephoto lens on an iPhone 13 Pro.” Sadly, these conditions we just created match exactly zero images. Let’s change that first filter dropdown from “date added” to “focal length” because we know that photos taken with the telephoto will have a focal length of 77 mm. The second condition defaults to “date added is in the last 30 days”. It’s important to know that you have this set to all because there could be smart albums where you want to see matches to one or more of the filters rather than all. In our effort, we do want to match photos that were taken with an iPhone 13 Pro and were taken with the telephoto. The important thing to note as soon as you add a second condition is a dropdown above the conditions that says “Match” and it’s set to “all” of the following conditions. To the right of our first condition defining the camera model, there’s a plus button to add another condition. If we right-click on our Smart Album in the left sidebar of Photos we can choose “Edit Smart Album”. (I know it’s really it’s a telephoto because it doesn’t zoom but they call it a zoom.) This means we can categorically say that any photo where the “Camera Model is iPhone 13 Pro” AND “focal length is 77mm” should be iPhone 13 Pro photos taken with the 3X optical zoom. On a big-girl camera, you can change the aperture of the lens even while keeping the focal length fixed, but on iPhones, both of these attributes are fixed in the cameras. iPhone 13 Pro Example Telephoto Image at Focal Length 77 mm The 77 mm is the focal length of the lens that took the image, and the f2.8 (which is more properly written as a fraction: f/2.8) is the aperture (opening) of the lens. You might know what those numbers mean but I’ll elaborate. I found a photo I took off the coast of Iceland that says, “Telephoto Camera – 77 mm f2.8”. Scroll through your photos until you find one you suspect was taken with the telephoto and look at the Info panel to see if you’re right. In order to figure out the filter, we have to first find a photo taken with the telephoto lens. Filter to Only Telephoto Images Using Focal Length We now want to further filter this down to just those taken with the telephoto camera, but we have some work to do before we can figure out how to match the telephoto images only. In my Photos library I now have a match for 3,825 photos and videos taken with my iPhone 13 Pro. It should start to autofill for you which helps with getting the spelling and spaces correctly entered. Change the second dropdown to “Is” and in the third dropdown enter the camera model, “iPhone 13 Pro”. I can change the dropdown of the condition from “Photo” to “Camera Model”. In my example, we want to find iPhone 13 Pro photos first, and then we’ll narrow it down to find the ones with the telephoto lens. In my example, I have 1417 favorite photos. By default the condition for this new Smart Album will be Photo is favorite. In Apple Photos, start by selecting My Albums in the left sidebar. The path to do this is more circuitous than I would have thought, which is why I’m setting up this story. One way to gather data on which lenses you really use on your cameras is through Smart Albums in Apple Photos. You might think you use it really often, but wouldn’t empirical data to make that decision be even better? The 13 Pro has a 3X telephoto, but you’re wondering how often you really use it. So let’s say you have an iPhone 13 Pro and you’re considering that upgrade to the 14 or 14 Pro. One of the differentiators of higher-end iPhones is their optical zoom capabilities. Perhaps you’ve always gone top-of-the-line because of the cameras, but this year you’re wondering whether that’s actually justified. Let’s say the next iPhone is coming out and you’re trying to decide which model you might need. I’ve been working on smart albums inside Apple Photos and I’ve found some interesting things.
