The 70-200mm f/2.8 is the most universally deployed professional zoom in photography. Wedding photographers, sports shooters, photojournalists, commercial photographers — across every discipline requiring reach and light-gathering in a single optic, some version of this lens has been on the camera. Canon’s RF version, redesigned for the mirrorless mount, is the current benchmark for the category. The RF 70-200mm f/2.8L IS USM shrinks the physical footprint of its EF predecessor significantly — the retractable design reduces the barrel length at 70mm to a degree that initially reads as implausible for an f/2.

There are lenses you respect and lenses you love. The RF 85mm f/1.2L USM belongs to both categories simultaneously, which is a rarer condition than it sounds. Mounted on the R5, this combination announces itself before you even fire a shutter. The lens is heavy — 1,195 grams — and the balance tips forward in a way that forces a deliberate grip. Canon is asking you to slow down, and the images it delivers in exchange for that patience are among the most seductive produced by any modern mirrorless system.

The EF 100mm f/2.8 Macro USM — not the L version, the original — is the overlooked sibling of Canon’s more celebrated L-series macro. At used prices around $350, it delivers 1:1 macro reproduction with optical quality that the price differential does not adequately explain. Via the Canon EF-EOS R adapter on the R50, it becomes a 160mm equivalent macro lens with full electronic communication and a use case that extends well beyond close-up work.

The arithmetic of cropped sensors and telephoto glass is one of the more useful free lunches in photography. The Canon R7 — a serious APS-C body with genuinely professional-grade autofocus and a 32.5-megapixel sensor — transforms the EF 70-200mm f/4L into a 112–320mm equivalent. A zoom range that, on full frame, would require an expensive, heavier f/2.8 lens or a dedicated super-telephoto prime. Here it arrives via a quarter-century-old zoom that trades used for well under $600.

The argument for medium format has always been tonal, not pixel-numeric. Photographers who have shot both full-frame and medium format systems at comparable resolutions consistently describe a difference in rendering — a three-dimensionality, a tonal gradation in transitions from light to shadow — that specification sheets struggle to quantify. The Fujifilm GFX 100S II paired with the GF 110mm f/2 is the most accessible entry point into that argument that currently exists.

The Helios 44-2 58mm f/2 is a Soviet-era lens manufactured at the KMZ optical plant in Krasnogorsk, produced in quantities so large that the secondary market is essentially inexhaustible. Clean copies sell for $30 to $80 depending on coating variant and condition. Via an M42-to-Fujifilm X adapter (approximately $15), it attaches to the X-S20 and produces images that Instagram’s lens simulation filters have been attempting to replicate, with limited success, for a decade.

The Jupiter-9 85mm f/2 is a Soviet optical instrument derived from the pre-war Carl Zeiss Jena Sonnar design, manufactured at the KMZ factory and exported in modest quantities under the Jupiter brand. Optically, it inherits the Sonnar formula’s characteristic rendering: a smooth background blur without the Helios 44-2’s swirling tendencies, strong center sharpness with a gradual rolloff toward the edges, and a color rendering — particularly in the green channel — that has a coolness contemporary photographers find refreshing after years of the warm-biased output from modern lens coatings.

Fujifilm refreshed the XF 56mm in 2022 and the photography community received the update with the mild suspicion that greets any revision of a beloved original. The original 56mm f/1.2 R was a cult lens — optically flawed in the right ways, character-rich, with a rendering style that felt closer to medium format than its APS-C designation suggested. The WR version had a lot to live up to. It more than earns its successor status.

Every discussion of Leica eventually arrives at the question of whether the price is justified. The M11 body costs around $9,000. The current Summilux-M 50mm f/1.4 ASPH adds approximately $5,500. Thirteen thousand dollars for a rangefinder with no autofocus, no video, no continuous burst worthy of the name, and an optical viewfinder that requires the user to manually compensate for parallax error at close distances. The question is fair. The answer is complicated.

Telephoto zoom ownership typically involves a familiar trade negotiation: reach versus weight versus cost, with meaningful performance in all three simultaneously requiring a budget that narrows the market to professionals and committed enthusiasts. The Nikon Z50 II paired with a used Canon EF 70-300mm f/4-5.6 IS II via the Sigma MC-21 EF-to-Z adapter disrupts that negotiation in a way worth examining. The EF 70-300mm f/4-5.6 IS II is one of Canon’s most undervalued lenses.
