iPhone 13 seems so far away, but time moves so fast these days that I feel like I'll wake up around the time Apple announces a new, new iPhone next fall. So, if you're one of those who skipped the iPhone 12 (as I was), I've found three great reasons to want to upgrade.

These notes have been circulating throughout the year from various respectable sources, and they just resurfaced in a MacRumors roundup.

However, since these significant hardware improvements are specific to the iPhone 13 Pro model, it is possible that other iPhone 13 models will receive more computational photo-related upgrades.

Shutterbugs will still choose the Pro. Analyst Ross Young predicts that the iPhone 13 Pro and Pro Max will have larger sensors. This will allow for larger pixels and allow the sensors to collect more light.

We hope that all of the iPhone 13 Pro and Pro Max cameras will have larger sensors, but it should be noted that Young has not stated which cameras will be upgraded. Incidentally, the iPhone 12 Pro's wide lens can capture 27% more light, one of the tricks to getting better images.

Here's some great news for those who shoot wider photos. Renowned analyst and Mac prognosticator Ming-Chi Kuo reports that Apple plans to increase the aperture of the ultra-wide camera on the iPhone 13 Pro and Pro Max.

Currently, the lens has an aperture of ƒ/2.4 and a five-element lens assembly, but Kuo speculates that next year's Pro iPhone will move to an ƒ/1.8 aperture and six-element lens. Like the larger sensor mentioned above, this will allow more light to enter the lens and also allow for shallower depth of field.

Since this improvement is relatively similar (more light) to the large sensor mentioned above, one would expect this change to an ultrawide sensor to result in (at least) a large sensor change to the main wide camera.

Again, we are talking about iPhone 13 Pro features (we wish we had news of a regular iPhone 13 camera), but at least it is an expansion of features away from only the most expensive iPhone 13.

Sensor-shift optical image stabilization (according to Kuo) on the iPhone 12 Pro Max will be available on both the iPhone 13 Pro Max and iPhone 13 Pro. Sensor-shift image stabilization, a feature that was primarily found on high-end DSLR cameras and Huawei phones prior to iPhone 12, is a boon for those who want to capture the clearest photos and videos.

On the iPhone 12 Pro Max's wide camera (main sensor), sensor-shift image stabilization can make as many as 5,000 adjustments per second to stabilize the lens.
