![]() ![]() ![]() What’s different really?īesides the obvious additional arrow slots that you are getting, there is one difference that I am particularly stoked on and that is the new XL mounting bracket. Paired with TightSpot’s Iron Clad Gaurantee and I am sold. The quiver has the same design, just with extra arrow slots, so I feel better about how many arrows I have on my backcountry hunts, haha. This has the same great construction that comes with all TightSpot quivers and the addition to the quiver is really so simple it’s hardly noticeable. Definitely not gonna leave you in pain from lugging around the extra weight. This 7 arrow quiver is pretty much identical to its 5 arrow sibling. My first impressions weren’t really much to think about to tell you the truth. I thought, “Could this solve my running out of arrows problem?” I knew that I had to get my hands on this thing immediately for my backcountry endeavors. It was a day to remember for sure.Īt the start of this year, I found out that TightSpot was actually coming out with a 7 arrow quiver. Just this past December, I was able to do just that and brought home my first archery buck. I loved the idea of the quiver being so much more closer to the riser, which would make it a lot easier to lay my bow in my lap while crab crawling my way down to a bedded mule deer. ![]() Like a lot of folks, I have been carrying a 5 arrow quiver for quite some time and as of a few years ago, that quiver has always been a TightSpot. This is especially true when I am backpacked into an area and have only the arrows that are in my quiver. I know that might sound hilarious, but it’s the truth for me. I don’t know about you, but whenever I miss an animal and lose an arrow, I start hoping I don’t run out of arrows. ![]()

![]() ![]() He talks Lexi’s weirdo neighbor Lonnie (played to perfection by local chef Ethan Darbone) into driving him around, and then lands a job selling weed for local queenpin Leondria (who Baker first noticed as a striving restaurateur in Roberto Minervini’s documentary “What You Gonna Do When the World’s on Fire?”).īut things don’t really turn around until he sees the girl working behind the counter at the Donut Hole in front of the refineries, where it stands out like an oasis on the lip of hell. Mikey is a larger-than-life suitcase pimp whose origin story probably involves Bradley Cooper’s character from “Silver Linings Playbook” stepping into the same telepod with Howie Bling and Tim Robinson, and he never stops working the angles. It seems that’s all he’s ever done with anyone’s feelings, or will ever be able to do. But what starts as “just a shower and a place to crash” soon turns into “let me sleep on the couch semi-permanently if I pay $200 a week.” And when Mikey inevitably worms his way back into Lexi’s everything and begins to sense that she might want him to stick around, our boy leverages her feelings for his own gain. Lexi and Lil might kill him themselves before Mikey even gets that far. Mikey is not one of those people.įrom the moment he starts banging on the door of the house where his estranged wife Lexi (theater actress Bree Elrod) still lives with her no-nonsense mother Lil (Brenda Deiss, a phenomenal local discovery who Baker spotted outside of a Porta Potty), it’s clear that Mikey will choke to death if he stays in Texas City for a minute longer than it takes him to get back on his feet. Some people can survive in an environment like that. It’s a story about people who are stuck in a purgatory that’s older than time itself. “Red Rocket” may be set in the months leading up to the 2016 election - a clever move that allows Baker and co-writer Chris Bergoch to borrow Trump symbology without having to deal with COVID - but the film rejects the unavoidable nowness of the director’s recent hits. Here, Baker ditches the corporate utopia of Disney World in favor of a more rustic vision of the American Dream, exchanging the ultra-real harshness of his recent films in favor of a 16mm fuzz that combines the velvet touch of early Spielberg with the invasive eroticism of Italian exploitation (Baker cites “The Italian Connection” and “Spasmo” as specific touchstones). While “Red Rocket” continues the “Tangerine” and “ The Florida Project” filmmaker’s hot streak of unpatronizing, street-level stories about sex work in the survival economy, the movie immediately establishes a new visual approach to that familiar terrain. But Mikey isn’t leaving anyone behind so much as he’s coming back home with his tail between his legs (the words “red rocket” are never mentioned in the film, but it doesn’t seem coincidental that the phrase is slang for a dog’s erection).īaker isn’t beating a similar retreat. It begins with the blaring shriek of NSYNC’s ear-piercing masterpiece “Bye Bye Bye” as a black-eyed Mikey suffers through the long bus ride of shame from California to Texas from the “who am I here to fuck?” hedonism of the San Fernando Valley to the “why the fuck am I here?” industrial wasteland of Refinery Row. ‘The First Slam Dunk’ Review: Takehiko Inoue’s Anime Smash Is One of the Most Thrilling and Unusual Basketball Movies Ever Made ![]() And he doesn’t stop trying to weasel his way deeper into any of those things for a single minute of Sean Baker’s utterly singular and weirdly lovable “ Red Rocket,” a roman candle of a movie that wonders if America’s pathological narcissism will ever burn itself out. ![]() ![]() Into their houses into their panties into their dreams for the future that Mikey incepts into their heads for his own benefit.

One-year warranty with a 30-day performance certification. The motor is also interchangeable with the #1001 fixed router base and the #6911 D-handle base for added versatility. Fully enclosed springs ensure smooth operation through the 2-1/2-inch plunge range. A large locking lever and a depth stop with a six-position turret make setting the bit to the proper depth a breeze. The plunge base has simple controls as well. Adjusting the bit depth when using the fixed base is as simple as releasing a lever and turning the motor within the aluminum base.Ī micrometer ring on the base acts as a reference for fine adjustments to within 1/64 of an inch. This eliminates the need to tap on the arbor to break the collet free, a practice that can damage the motor. The included 1/4-inch and 1/2-inch collets have an auto-release design that prevents router bits from becoming frozen or trapped in the collet after use.

Tamron makes some very good alternatives, with 16-300mm and 18-400mm options that go considerably wider and longer, respectively. What's more, it's super cheap, too.Ĭanon’s own-brand EF-S 18-200mm superzoom lens is pretty ancient and lacking in telephoto reach. ![]() Although f/2.8 isn't a super fast aperture, image quality is excellent and it's a charming little prime lens for travelling light. Teeny tiny and extremely lightweight, this 'pancake' lens is less than an inch in length and only weighs 125g. Great-value option: Canon EF-S 24mm f/2.8 STM Further good news is that the front element neither extends nor rotates during focusing. Meanwhile, autofocusing is fast due to the rear-focusing mechanism that drives the smaller, rear elements of the lens via a ring-type ultrasonic system. ![]() Sharpness is impressively good, even at the widest available aperture. You get fast shutter speeds in low light without needing to boost your ISO settings, but you also get a nice and tight depth of field. It's also one of Sigma's 'Art' class lenses, meaning that you get a beautiful construction, as well as a fast f/1.4 aperture. It delivers impressive image quality and comes at a bargain price.Ĭanon's 1.6x crop factor makes this Sigma 30mm equivalent to around 48mm - that's pretty close to the classic 50mm focal length beloved by many. While it doesn't have the f/2.8 constant option of the Canon, f/2.8-4 is still fairly wide. This third-party option is fairly compact and lightweight. Great-value option: Sigma 17-70mm f/2.8-4 DC Macro OS HSM | C You pay a price for these great specs though, with it being the most expensive standard zoom for APS-C format Canon cameras - still if you need something versatile for everyday usage, it's a great option. There's also a range of enthusiast-friendly features such as ring-type ultrasonic autofocus and a focus distance scale beneath a viewing window. This classic zoom lens is the only one on the list to feature a fast and constant (meaning that it's available through the whole zoom range) f/2.8 aperture, making it great for creating shallow depth of field effects and shooting in low light. While the camera bodies of 10 years ago might look outdated nowadays, that's less of a problem with lenses where designs don't change quite so rapidly. This lens is now more than a decade old, but don't let that stop you from considering it. As well as outright winners in each category, we’ve included some best-value alternatives if you're on a tighter budget. ![]() However, third-party lenses from the likes of Sigma and Tamron often give similar or even better performance than own-brand Canon lenses, and at more competitive prices.įor this piece, we put all of the main contenders in the various categories through their paces with rigorous lab testing and shooting in a variety of different 'real-world' scenarios.įrom those results, here are the best-buy lenses for your Canon APS-C camera body. If you’ve got a Canon camera, it might seem sensible to use Canon lenses. We’ve put all of the main contenders through their paces with rigorous lab testing and shooting in all manner of ‘real-world’ scenarios Canon or third party? The classifications used by Sigma are DC (APS-C) and DG (full-frame) and for Tamron it’s Di-II (APS-C) and Di (full-frame). There are no problems using EF lenses on APS-C format cameras, but you can’t use an EF-S lens on a full-frame DSLR. The EF-S variant was launched in 2003, to suit Canon DSLRs with smaller, APS-C image sensors (such as the 90D).

Opere matematiche di Eugenio Beltrami, pubblicate per cura della Facoltà di Scienze dalla Regia Università di Roma. Of course, in the projective-space model, often called Riemann’s non-Euclidean geometry, one not only has to give up the infinite extension of straight lines, but also the fact that a line divides the plane into two parts or, which is about the same, orientability of the plane.Īhlfors, Lars Valerian. Kelin realized the role of this model in the discussion of non-Euclidean geometries. Clifford used the two-to-one covering of the real projective plane by the sphere to exhibit a geometry with positive constant curvature in which (1) there was just one line through two points (2) space was homogeneous and isotropic and (3) there are no distinct, parallel straight lines. Some of the principles used by Saccheri had to be abandoned: uniqueness of the line through two points, it seemed but also the infinite extension of lines (Riemann seems to be the first to point out that the right geometric requirement is not that the straight lines have infinite length – what he calls “infinite extent of the line”, translated in “unboundedness” in modern netric space theory –, but that one finds no obstructions while following a straight line – a property he calls “unboundedness”, translated nowadays in “metrically complete and without boundary”). In the Habilitationschrift, Riemann offered the sphere as a model for a geometry in which no parallel existed. This was considered to be a major problem by Beltrami, who was looking for a geometry in which all principles of Euclidean geometry hold true, but the uniqueness of parallels, but not for Riemann. All rights reserved.The obtuse hypothesis holds on a sphere, using geodesics (great circles) as straight lines but on a sphere we do not have uniqueness of the geodesic through two points.
