iPhone 12Pro Max bumper

Protecting the lens assembly.

It’s not that easy to find a pure bumper for the iPhone 12Pro Max. Most cases come with a variety of front and rear covers, neither wanted by this user as I use a belt holster.

I did not want to get a case for the iPhone 12, to keep bulk down and to retain the better grip afforded by the square sides. However I did find the sides rather slippery but, more importantly, noticed that the protruding lens assembly meant that the iPhone would not rest flat on a desk or table, but would rest that corner on the lenses themselves. Not good.

So I caved and got one of the above. It’s slightly less slippery than the native edge, the square profile of the sides is retained, the touch of the buttons remains good (though the mute switch is a bit tough to access) and it has corner protrusions which protect the lenses when the iPhone is placed lens-down on a flat surface. While the package included a screen protector I consider that a waste of time as I have never known an iPhone screen to scratch unless something truly thoughtless is done to it, like putting it in a pocket with unprotected keys. As for covering the lovely Pacific Blue back, why on earth would you want to do that?

iPhone 12 Pro Max – some observations

November 14, 2020iPhoneThomas Pindelski

The world’s best cellphone gets better.

I opted for the Max large version of the iPhone 12 Pro for two reasons. I really want to obsolete my 7″ Kindle Fire for reading (it’s a nice small size and weight which can be held in one hand when lying on the sofa) as fewer gadgets are always a good thing. And because the iPhone 12 Pro Max has some nice enhancements over the iPhone 12 Pro and 11 Pro when it comes to the cameras. Night Mode is now available on both 12 Pro models for the UWA lens (not available in the iPhone 11 Pro) and internal processing sees to it that the objectionable UWA ‘mustache’ distortion is no longer present.

Uncorrected UWA images – iPhone 11 Pro vs. iPhone 12 Pro Max.

You can read about the high distortion levels in the UWA lens in the iPhone 11 Pro here and follow the link to my LR/PS distortion correction profile from that piece. Suffice it to say, as the above images disclose, there is no need for a distortion correction profile with the UWA lens in the iPhone 12 Pro Max. Masochists can go to Settings->Camera->Lens Correction to turn off in camera distortion correction for both the UWA and standard lenses.

Another reason to upgrade to the iPhone 12 is the shape of the case. The iPhone 12 has reverted to the slab sided design seen in the iPhone 4 and boy, is it wonderful to hold after the slippery eel that is the iPhone 11. So much so, that while I am sticking with a (larger) belt holster for the iPhone 12 Pro Max, I no longer use a protective cover or case as it’s so much nicer to hold naked in the hand. The worst aspect of the iPhone as a full time camera has always been its awful ergonomics, and this is a significant step in the right direction.

There’s another ergonomic upgrade courtesy of software changes. Go to Settings->Accessibility->Touch->Back Tap and set it as follows:

Back Tap.

You can now simply double tap the rear of the iPhone to release the shutter; sadly no single tap option is available. But either way, this is a strong argument to avoid the use of any sort of protective cover, or to cut a hole in the back if you do use one to permit the use of Back Tap. I have found that the UWA is so wide that getting your fingers out of the way is a challenge using Back Tap with that lens, but it’s easy with the other two.

Speaking of lenses, the ‘long’ lens, still at 50mm in the iPhone 12 and 12 Pro, is now 65mm in the iPhone 12 Pro Max. Until a periscope zoom comes along in later iPhones, this is a step in the right direction.

Finally, the new LIDAR detector permits accurate determination of focus even in darkness. This image of my son watching TV on the patio was taken in almost total darkness, the iPhone advising me to keep still during the three second hand held exposure. This is magic. Why would anyone revert to the dated, incompetent offerings from Sony, Nikon, Canon et al?

LIDAR assisted Night Mode in near total darkness. 65mm lens.

As for obsoleting that Kindle Fire as a book reader, here are the key statistics:

Kindle Fire – screen diagonal 6.8″, weight 10oz, battery life 7 hrs.
iPhone 12 Pro Max – screen diagonal 6.4″, 8.6 oz, battery life 20 hrs.

Hast la vista Kindle.

More when Apple Pro RAW becomes available in the iPhone 12 with an upcoming iOS release.

The iPhone 12 Pro is the best camera in the world for 99% of users.

You think the iPhone 12 Pro Max is expensive? Run the numbers. Read this. It costs $300 a year.

Mac Mini – 2020

November 11, 2020MacintoshThomas Pindelski

The M1 CPU comes to the Mac.

The first Apple desktop computers used the MOS 65xx series of CPUs through November 1990, with the Apple IIC Plus. This was the Steve Wozniak designed series of machines which was replaced by the Macintosh in January 1984, though it took a while to die.

The Macintosh brought the innovative graphics interface to the screen and the Motorola 68000 series of CPUs saw to the heavy lifting. The last Macintosh, the Quadra 630 was sold in April 1996 by which time Motorola had proved unable to meet Apple’s growing CPU performance demands.

By the time the iMac was introduced in May 1998 Apple had dropped Motorola and retained IBM, using its broadly available series of G3 CPUs. These were very capable machines and the CPU also found itself into the G3 Powerbook laptop in November 1997 and constituted what was broadly recognized as the best laptop available. IBM enhanced performance in its CPUs in the G4, which also went into these machines, but the even faster G5 only made it into the laptop. That’s because it put out enough heat to make toast with your morning coffee and Steve Jobs realized that IBM’s day was done as CPU supplier to Apple. You can read about my sad experience with the G4/5 iMacs here, and the less said the better. Not only did the CPU overheat, the GPU was even worse – thank you Nvidia. Nvidia was dropped soon after in favor of ATI for graphics processing.

Jobs retained Intel, and the iMac of early 2006 used the Intel Core Duo CPU. This used less power, saw to it that you brought the toaster out of storage as the Intel CPU ran cool and, as a reult, Intel and Apple looked forward to a long and fruitful relationship. Meanwhile, toaster sales took off.

That relationship saw sunset this week with the introduction of the first M1 powered MacBook Air and the latest Mac Mini.

Mac Mini 2020 with the M1 CPU.

The M1 is a variant of the splendid Axx series of CPUs found in the iPhone. Anyone using an iPhone 11 with the A13 on board knows only too well how this CPU performs. Extremely low power consumption, heat output so low that no power hungry cooling fan is needed, and the whole thing sells for a starting price of $700. Add your disk drives, keyboard and display of choice and a mouse and you have a very capable desktop for relatively little money.

When Apple migrated from the IBM G series CPUs to Intel they also wrote one of the greatest utilities of the time, named Rosetta. This came with every Intel Mac and would permit the running of G3/4/5 apps with no input from the operator. It was invisible, and the performance penalty compared with later Intel apps was modest. Brilliant. I recall Steve saying that it took two years to develop Rosetta, and it was perfect.

Apple is doing something similar with the M1 powered Mini and Air and once again older apps promise to run seamlessly, though native versions can be expected soon and should outperform the Rosetta-translated ones.

In much the same way that Apple is moving away from the serial intellectual property thieves at Samsung for its cell phone components, the move to the in-house designed M1 will confer like independence and pricing power with the Intel bond broken. Most importantly, it gives Apple full control over software design, no longer beholden to someone else’s chip architecture. Here are the M1-powered MacBook Air performance specs:
