The mammoth Photokina photo fair is going on this week, and that means tons of photo goodies. Small, manual cameras with big sensors are the game this year — unless you’ve got $20,000 to burn, in which case Leica’s new novelty camera might be up your street. We round these out with Gadget Watch's usual collection of bags, cases and gadgets.

The sweet-looking LX-100 is Panasonic’s take on the Fujifilm X100, only it comes with a zoom lens instead of a fixed one, and a plain EVF instead of the X100-series’ amazing hybrid viewfinder. It packs in a big Micro Four Thirds sensor, has manual dials for everything and the 24-75mm equivalent lens runs from ƒ1.7-2.8. $900

It looks like a sunglasses case crossed with a taco, but the Bison Wallet is in fact an iPhone case that manages to carry some cards or cash in a minimal, almost unnoticeable pocket formed from an extra flap of leather. It’s a clever take on the wallet case, and one which doesn’t leave you with a wedge of crap on your back jeans pocket. $75

The biggest shock about Booq’s Taipan Shock is the price. For $95 you get a great bag with Booq’s great organizational design, which gives you tons of pockets and sleeves for your gear, but somehow doesn’t force you into one way of using it. There’s a section for a MacBook, an outside pocket for an iPad, plus all kinds of spaces inside for bottles, clothes and accessories. $95

Rickshaw makes some of the finest bags known to man, and now it also makes them reflective. See-me-in-the-dark Reflective Performance Tweed is a shiny variant on the regular Performance Tweed, a classy fabric made from recycled water bottles. Backpacks and messenger bags can be had in solid or striped variants, and they’re all as ultra-light and ultra-tough as ever. From $59.

Who wants to toss their Apple Watch onto their nightstand while they sleep? Not you, and not me. No, we want the DoDocase charging stand, carved from walnut and with a cable router to keep things tidy. I like that you can just hang the watch on here and charge it. You can even have the thing monogrammed, rendering it tacky as hell. $80

$20,000 will buy you a digital Leica with no LCD, no autofocus, not even automatic exposure. You get a shutter release button, a shutter speed dial, an ISO dial and the aperture and focussing rings around the lens. That is it. It’s a rangefinder camera with all the limitations of film. You can’t even chimp to check you got the exposure right. Loaded hipsters are ecstatic. $20,000

Panasonic has put a one-inch sensor and a Leica lens in a phone. To be fair, it’s more of a camera with a phone built into it, but seeing as my iPhone gets used more as a camera than anything else, that’s not a bad choice. That’s the same sized sensor as in the Sony RX100, paired with a 28mm (equivalent) ƒ2.8 lens. There’s even a physical click-wheel around the lens. It’s just a shame it runs Android. €900

If you hate on-the-go iPhone-charging hassle, then you need the Photojojo keychain charging Tassle, a Lightning or microUSB cable that dangles from your bag or keys until needed. Outside it’s leather, inside there are your charging plugs, kept safe with a magnetic closure. Comes in pink or brown, for $60

Bags, bags, bags. Literally – there are three hot bags in this week’s gadget roundup, and if you buy them all, you’ll be out by around a grand. Or you could buy the ultra-expensive Leica M-P, a new camera so minimal it doesn’t even have the trademark red dot on the front, yet still costs $8,000. Or you can go to the other end of the price range and pick up LensBaby’s new iPhone optic for just $70. And that’s just the beginning…

H.O.T. Those are the three letters that best describe Pad & Quill’s new Attaché bag, a beautiful leather satchel with unbreakable, high-copper-content hardware and parachute-grade stitching on the outside. Inside, you'll find padded MacBook and iPad pockets, plus orange suede pocket linings.

As a bonus, the marketing copy for the Attaché seems to have been written by Hannibal Lecter, containing this line: “Your taste buds and your liver deserve top shelf [and to be] savored in a glass.” (some words added for comedic effect). How much? $420

You can’t get much simpler than the Dragon device holder – it’s a pair of aluminum clips that snap onto the cylinder at the back of your Apple wireless keyboard and slide up and down, letting you space them to fit anything from an iPad to an iPod nano. The clips have a tail at the back to provide stability, and a little lip at the front to hook the bottom edge of your gadget. If you use a full-size keyboard with your iPad, this little gadget should be in your bag. $25

This bag comes from Brooks, the English bike saddle maker. Weighing in at a hefty 1.6 kilos (well over 3 pounds), it has a roll-top enclosure and adjustable clips that can attach the bag to the rear rack of your bike. The body is “water resistant cotton” and the straps are leather. The price? Around $400.

In: 2GB RAM (double that of the Leica M). Sapphire glass cover for the camera's rear LCD.

Out: The Leica red dot

Price? $8,000

There’s little to say about KERO’s micro-suction portable battery other than, “What a frikkin’ great idea.” It’s a regular, modest-capacity backup battery (1800mAh, which will get your iPhone back to 75 percent) with a USB port and status-indicator LEDs, but on one side it has a micro-suction layer so you can stick it to the back of your iPhone, over and over. This is so much smarter than having to use a special case to clip the battery on, or just using a case with a built-in battery pack. Or you could do what I do, which is use a regular backup battery and a rubber band. $19

The Pyle PSBCG90 Smart Bicycling Computer tracks your rides with GPS and displays them on Google Maps back at your computer. You can also hook up any ANT+ accessories wirelessly (heart rate and cadence sensors, power meters and so on), and even challenge yourself, Mario Kart-style, using the ghost-route feature. It looks like a decent alternative to something like the Garmin EDGE 500, and it costs only $130.

Lensbaby now makes a sweet-spot lens for the iPhone. It sticks on with magnets (you need to stick the included ring over the iPhone’s lens) and blurs everything in your photos except a sharp sweet spot in the center. It's just like the regular Lensbabys, only less adjustable and made for the iPhone. There’s another neat feature – the front has a metal ring on it, too, so you can attach any other iPhone lenses you have onto the Lensbaby for some really freaky FX. $70

The Magnus Air updates the minimalistical Magnus that originally shipped for the iPad 2, way back in the mists of 2012. Typical of TenOne’s design, it is so simple it almost doesn’t exist, sticking to the Air with magnets and adding an almost invisible stand that holds your iPad at 22 degrees from the vertical, and at 22 degrees from the horizontal if you lay it down to type. And that’s it – an aluminum bracket that looks kinda like a taco shell, for $40.

Fact: Cobra Brief is the name I gave to my favorite pair of underwear. And now, it is also the name of a “business laptop” bag from Booq. It has all the compartments and pockets you’d expect, with a space for almost literally everything, plus an outer quick-access pocket for your iPhone and iPad. You can even hook it onto the top of your carry-on trolley, allowing you to be one of those morons who sneaks too many bags into the plane and takes up all the overhead bin space. $295
