L-Brackets and Arca-Swiss-compatible lens foots were on my “nice-to-have” list... until I purchased a couple of them. Now I can't live without them. Really Right Stuff (RRS) brackets and foots feature QD (Quick Detach) mounting sockets that I use with my Magpul QD camera strap. RRS gear is a bit on the pricey side, but they make very high quality products that hold their value. When I moved to the Sony system, both my RRS L-Bracket and RRS Lens Foot sold within a couple of days on Ebay at about 70% of retail price.
Really Right Stuff Modular L-Bracket for Sony Alpha a1, a7RIV, a9II, and a7SIII - https://geni.us/RRS_Sony_a1_LBracket
I prefer the modular RRS L-Brackets on Sony cameras, as the bracket improves ergonomics and makes the camera feel a bit "beefier." However, RRS also has a one-piece Ultralight L-Bracket that fits Sony Alpha a1, a7RIV, a9II, and a7SIII cameras if that is something you prefer.

A lot has been mentioned online about the RRS Sony a7RIII L-Bracket and how you need to move the battery compartment door from the camera to the L-Bracket. I had no difficulty moving the door, and doing so doesn't seem to affect the weather sealing either, as the bracket has a built-in rubber battery compartment gasket. But because of the battery door design, many photographers prefer the Kirk Photo Sony a7RIII L-Bracket. Like the Really Right Stuff L-Bracket, the Kirk bracket has a QD (Quick Detach) socket, and it is also quite a bit less expensive.

I highly recommend replacing your factory lens foot with an Arca-Swiss compatible lens foot. The convenience is worth every penny. This lens foot includes a QD socket as well.
At least one spare battery is a must-have, and a portable charger is a definite nice-to-have as an alternative to carrying a truckload of spare batteries. I highly advise using only manufacturer-approved power accessories.

This charger can be used to power your Sony Alpha a7RIII and a1 cameras while you shoot. It is PD rated, air-travel friendly, and you can also charge your phone and computer with it. Be sure to check your camera's manual, or website support pages for compatibility before purchasing.
Tether Tools TetherPro USB-C to USB-C 15' Tethering Cable - https://geni.us/TT_Tethering_Cable
A tethering cable is another one of my "nice-to-haves" turned must-haves. This particular cable is a USB-C to USB-C bright orange (visibility) cable, but Tether Tools carries the same cable with other connector options too. Be sure to read your camera manual and check your computer ports to see which connectors are appropriate for your setup.
Tether Tools TetherGuard - https://geni.us/TT_TetherGuard
Helps prevent USB-C port damage while shooting tethered. Purchasing this product is money well spent.
**Be sure to consult your camera's manual before purchasing a CFexpress card, as there are two types: Type A and Type B. Sony series cameras require Type A cards.
The Sony Alpha a1 camera takes CFexpress Type A memory cards and UHS-I/UHS-II SD cards in both card slots. Both card slots will read UHS-II cards at speed. CFexpress cards are expensive but faster. UHS-I and UHS-II SD cards are not as fast, but they are far more affordable (UHS-II cards are faster than UHS-I cards.) The Sony Alpha a7RIIIA camera only takes UHS-I and UHS-II SD cards. However, one card slot has a UHS-I card bus and the other has a UHS-II card bus. You can use UHS-II cards in both a7RIIIA card slots, but the second card slot won't be able to take advantage of UHS-II speed capabilities. When it comes to UHS-I/UHS-II SD cards, I prefer to carry several cards with a lower storage capacity, rather than a few high-capacity cards, as even the best memory cards fail on occasion. A 128 GB card failure is painful, but not as painful as a 512 GB (or larger) card failure when it comes to lost files.

If you are only using UHS-I/UHS-II memory cards, you may not need this card reader since most computers have a built-in card reader. But if you are using CFexpress Type A memory cards, you must have an external card reader such as this one.
Sony Zeiss T* Multicoated Clear Protective Filters - https://geni.us/Sony_Clear_Filter
Ask a group of photographers how they feel about using protective lens filters, and you will hear differing opinions. I come down on the side of using them, especially in wet or dusty conditions, or during goober-laden pet and equine shoots. Our main reason for using them is that over time, cleaning the front of a lens with any type of lens cloth or lens wipe, no matter how gentle, will lead to micro abrasions. I’d rather this happen to my filters than my lenses, and I have decided to stick with native Sony clear filters. The main thing is, if you are going to use a UV or Clear filter to protect your expensive lenses, I suggest purchasing high-quality filters - cheap filters can negatively impact image quality.
**It can be challenging to find a high-quality filter system that works across an entire lens collection, especially if you own more than one non-threaded ultra-wide-angle lenses. I hope this information helps!
Both Kase and NiSi make very high-quality filter systems. I prefer the Kase magnetic filter systems as they are quick and convenient to install and use. However, if you own the Sony FE 12-24 f/2.8 GM lens, I suggest considering the NiSi S6 150mm filter system.
Hybrid Square and Magnetic Circular Filter System: Kase Armour 100mm Magnetic Filter System
**Kase Wolverine Magnetic Circular filters are not compatible with the Kase Armour System - these are two separate systems.
The Kase Armour 100mm Magnetic Filter System, which is compatible with all of the lenses listed on our Camera Bodies and Lenses page except the Sony FE 12-24 f/2.8 GM lens, (see the NiSi S6 Filter section below), provides the best of both worlds. Photographers can still use 100x100 mm or 100x150 mm filters while taking advantage of the convenience a magnetic filter system provides. The Kase Amour filter system starts out with a "base" adapter ring that attaches to your lens on one side, and has a magnetic surface on the other. Next, a magnetic 100mm filter holder snaps to the outside of the magnetic adapter ring on the lens. The magnetic filter holder accepts one magnetic circular polarizing filter (or magnetic circular ND filter) on the back of the holder, and a second magnetic circular ND filter on the front. Finally, up to two 100x100mm or 100x150mm filters snap to the filter holder via magnetic frames. The filter holder has a gear on the side that turns the CPL independently of the 100mm filters. In addition to the standard thread size adapter rings included in the kit I have listed below, if you own the Sony FE 12mm f/1.8 and/or the Laowa 12mm f/2.8 Zero-D lenses, you will also need to purchase the specialty adapter rings, also listed below, since neither of these lenses have filter threads. If you already own a set of 2mm-thick 100x150mm or 100x100mm filters, you can simply purchase a couple of Kase Armour Magnetic Filter Frames and continue using your existing filters.

Kase Armour Adapter Ring for Laowa 12mm f/2.8 Zero-D Lens - https://geni.us/Kase_Armour_Laowa_12mm
I recommend purchasing the entry-level filter kit and then purchasing only the circular and/or 100mm filters you need. Keep in mind that if you purchase or already have a 100mm filter, you will need to purchase a magnetic filter frame, or swap out the frame that comes with the kit.

Circular Magnetic Filter System for Threaded Lenses: Kase Wolverine Magnetic Circular Filters
**Kase Wolverine Magnetic Circular filters are not compatible with the Kase Armour System - these are two separate systems.
If you prefer to the simplicity and space-saving convenience of magnetic circular filters on your lenses with filter threads, this is the filter system that I recommend. The trick to purchasing the Wolverine Magnetic Circular filter system, is to buy filters that fit your widest diameter (filter thread size) lens, and then purchase Kase magnetic step-up rings to adapt your smaller lenses to the larger filters. Kase makes magnetic step-up rings in several filter thread size combinations. You can also attach additional standard (non-magnetic) step-up rings to your smallest lenses if need be. So if you own a Sony lens with 95mm filter threads, such as the Sony FE 200-600 f/5.6-6.3 G OSS lens, or think you might purchase one in the future, I suggest purchasing a 95mm set of Kase Wolverine Magnetic Circular filters. At the time of this writing, the largest lens filter thread size in the Sony lens lineup is 95mm. Lastly, if you purchase a 77mm or 82mm Wolverine Magnetic Circular Filter set (I don't recommend going smaller than that), Kase makes a nifty and affordable magnetic lens hood. Select the lens hood and magnetic adapter ring kit that is the same diameter as your Wolverine Magnetic Circular Filter set, and use standard (non-magnetic) step-up rings as necessary to adapt your smaller lenses.

Filters For Sony FE 12-24 f/2.8 GM Lens Owners: NiSi S6 150mm Filter System
At of the time of this writing, the Nisi S6 system can be adapted to all of the lenses I have listed on our Cameras Bodies and Lenses page, with the exception of the Laowa 12mm f/2.8 Zero-D lens (see the Kase Armour 100mm Magnetic Filter System below.) The NiSi S6 Filter System starts with a "base" kit consisting of three pieces: a lens adapter ring, a filter holder, and a circular polarizing filter (CPL.) I recommend purchasing the kit that includes the NiSi S6 True Color Nano Coated Circular Polarizing Filter listed below. You only need one each of the filter holder and CPL, so this kit will serve as the base of your filter system. Then, if you would like to use the NiSi S6 Filter system on the a Sony FE 14mm f/1.8 lens, and any of the other threaded lenses listed on our Camera Bodies and Lenses page you will need to purchase the two additional filter holder adapter rings: a Sony FE 14mm f/1.8 lens adapter ring, and a universal adapter ring for lenses with standard filter threads (purchase includes 82mm, 95mm, and 105mm step-up rings.) From there you can purchase any additional step-up rings you need, and of course the filters themselves if you don't already own a set of 150mm filters. The Nisi S6 filter holder accommodates two 2mm-thick 150mm filters.
