Sony E-mount dominates: 5 deals (June 10)

Sony E-mount had a rough Tuesday — in the best possible way. The A7 IV (Sony's workhorse full-frame body, MSRP $2,498) shed $280 overnight, landing at $1,399 on MPB (the used-camera marketplace with grade-rated inventory). That's the largest single-day dollar drop in this watchlist's entire June run, and it happened while three Sony lens all-time lows (ATLs) held steady for a fourth consecutive day. On the lens side, a brand-new ATL just opened on Fujifilm's 50mm f/2 WR. Nikon Z 28/2.8 is grinding through Day 11. Canon EF L-glass has 14 lenses under $500, but the $389 flash sale from yesterday absorbed in under 24 hours — the clearance wave is real, but individual windows last a few hours, not days.

System weather: Sony E-mount, across the board. The FE 24/1.4 GM (G Master — Sony's professional prime tier), FE 85/1.8, and FE 24-105/4 G have held their ATLs for two to four straight days. The A7 IV floor broke to a price not seen in the six-month tracking window. The A7R V floor is holding despite 114 units in supply. Nikon Z body prices are stable-to-rising. Canon RF has no deals. Panasonic S5 II is at Day 13 — which means $1,419 is the market price, not a closing opportunity.

The A7 IV (full-frame 33MP Sony body, rated 200,000-actuation shutter lifespan) dropped from $1,679 to $1,399 between June 9 and June 10, a $280 cut in roughly 22.5 hours. 1 That's a 16.7% overnight move, with 187 units sitting in MPB's inventory right now.

The visible listings, sorted high-to-low, show Like New copies at $1,869–$1,899 with shutter counts from 929 to 6,100. The $1,399 floor unit sits deeper in the listing, likely a Well Used grade copy with higher actuation counts. MPB's Well Used grade means fully functional with visible cosmetic wear. At 187 units and a body rated for 200K actuations, there's enough supply to shop carefully rather than grabbing the cheapest unit.

6-month price range: $1,399 is the new floor; the A7 IV was at $1,679–$1,689 as recently as yesterday, a level it had held for multiple weeks prior. Shutter count: not disclosed at floor tier; visible Like New units run 929–6,100 actuations. Known red flags: none. The A7 IV has no documented recall batches or serial range defects.

Verdict: Buy — shop the listing, not just the floor. At $1,399, the A7 IV is now below the price of several APS-C flagships. The 187-unit depth rules out a one-off pricing error. Check shutter count before committing: for $1,399, target under 50,000 actuations. The visible Like New copies at $1,869–$1,899 with sub-10K counts are a better value than the floor unit if condition isn't disclosed — $100–$150 more for a confirmed low-count body is worth it.

Pair with: Sony FE 50mm f/1.8 at $117 (Well Used, 110 units available). 2 A full-frame body plus a native 50mm prime for $1,516 combined. Or the FE 24-105mm f/4 G OSS at $444 (66 units, Day 4 ATL) for a one-lens travel setup. 3

Day 2. The FE 24mm f/1.4 GM (G Master ultra-wide prime, MSRP $1,398) held its ATL of $399 today with 25 units available, up from the initial "10+" count yesterday. 4 Price range sits at $399–$879 across those 25 units. The floor unit isn't visible in the top-8 sorted high-to-low, so it's a lower-grade copy — MPB sorted pages always show the priciest first.

Two-day confirmation at a first-time ATL with inventory ticking up is a real signal. If demand were outpacing supply, the count would be dropping; instead, more trade-ins are arriving at the same floor price.

6-month price range: $399 is the first time this lens has hit this level in the tracking window. Excellent-grade units start at $854. Shutter count: N/A (lens). Grade at $399: unconfirmed but likely Well Used by position in the listing. Check front and rear elements for cleaning marks or coating haze; G Master front elements are large-diameter and collect handling marks. Known red flags: none.

Verdict: Buy — verify glass condition. At $399 for a G Master prime, cosmetic wear is acceptable if optics and autofocus check out. At 72% off MSRP, this is a legitimate entry point into Sony's top prime tier for E-mount shooters. The two-day hold plus inventory growth is the strongest confirmation this lens has shown.

Pair with: Sony FE 85mm f/1.8 at $149 (Pick 3 below). 5 A 24mm GM ultra-wide plus a sharp portrait prime for $548 combined.

Day 4. The FE 85mm f/1.8 (Sony's full-frame portrait prime, MSRP $598) has held $149 for four consecutive sessions with 10+ units still available. 5 The direct product page was Cloudflare-blocked today, so the $149 floor comes from the search result, which reliably surfaces floor pricing. Exact inventory count is unavailable; "10+" is MPB's display cap.

Four days at the same ATL without a break is unusual on this platform. Short-lived floors typically reset within two sessions. The FE 85/1.8 has now outlasted the EF 24-70/2.8L II (bounced after Day 1), the FE 50/1.8 spike (reverted same-day on June 9), and every Nikon Z lens floor except the Z 28/2.8.

6-month price range: $149–$374 on MPB. Shutter count: N/A (lens). Grade at $149: not confirmed from today's data; prior sessions showed Well Used copies at floor. Inspect front and rear elements. Known red flags: none. The FE 85/1.8 has no documented production defects and is optically well-regarded among non-GM Sony primes.

Verdict: Buy. Day 4 means the window is stable, not closing. At $149 for a fast portrait prime on full-frame E-mount, a functional copy with clean glass is worth buying even at Well Used grade.

Pair with: Sony FE 24-105mm f/4 G OSS at $444 (66 units, also Day 4 ATL). 3 A portrait prime plus a versatile travel zoom for $593 on Sony full-frame.

Brand-new ATL today. The XF 50/2 R WR (Fujifilm's weather-resistant 50mm f/2 for X-mount, roughly equivalent to 76mm full-frame, MSRP $449) dropped from $269 yesterday to $244 today, a $25 cut (-9.3%) on a lens that had itself broken a record the day before. 6 Twenty-seven units are available, up from 25 on Day 1, with listings from Like New down to Good across the visible range.

The sibling lens, the XF 35/2 R WR (53mm-equivalent), has held $249 for seven consecutive days. The 50/2 WR is now $5 cheaper at floor, an unusual inversion: longer focal lengths in matched lineups don't typically undercut shorter ones.

6-month price range: $244 is the new all-time low; previous floor was $269, range runs to $419. Shutter count: N/A (lens). Grade: Good through Like New across the 27 units; the $244 floor unit is likely Good or Excellent. Known red flags: none. Fujifilm's WR designation has held up consistently in the used market.

Verdict: Buy. Day 1 of a new ATL with accelerating drops and growing inventory. The WR build makes grade calls more meaningful: a Good-grade WR lens that handled weather is different from a Good-grade non-WR body that sat in a bag and got dinged. At $244, X-mount shooters have a sealed short-telephoto prime at its lowest recorded price.

Pair with: Fujifilm XF 35mm f/2 R WR at $249 (73 units, Day 7 ATL). 7 A matched WR two-prime kit — 53mm-equiv. normal plus 76mm-equiv. short-tele — for $493, both at all-time lows.

Day 11. The Nikkor Z 28mm f/2.8 (Nikon's native Z-mount wide-normal prime, MSRP $296) has held $154 on MPB for eleven consecutive sessions. 8 Today's direct product page loaded cleanly and confirmed inventory grew from the prior "10+" cap to 15 units, price range $154–$199. The grade at the $154 floor is Like New, confirmed. The first page (sorted high-to-low) shows seven Like New copies at $199 and one at $189.

Eleven days is the longest active ATL streak in the current watchlist. Every other Nikon Z lens from the early June windows has bounced: the Z 50/1.8 S jumped $105, the Z 85/1.8 S jumped $100. The Z 24-70/4 S dropped to $309 today (a new candidate to watch for tomorrow). The Z 28/2.8 is the sole survivor, and it got a fresh inventory injection today rather than attrition.

6-month price range: $154–$199 on MPB. Shutter count: N/A (lens). Grade at $154: Like New, confirmed. Known red flags: none. The Nikkor Z 28/2.8 is a compact optical design with no documented defects at any serial range.

Verdict: Buy. Day 11 with confirmed Like New grade at floor and inventory replenishment is as clean a signal as this format produces. The usual concern with long-running ATLs is grade degradation — cheap units dwindle to parts-only copies. That's not happening here: 15 Like New units at $154, with the bulk of the listing still at $199.

Pair with: Nikon Z7 II at $1,289 (50 units, Day 2 of a new floor). 9 A 45.7MP full-frame Z body plus a wide-normal prime for $1,443 combined. The Z7 II floor grade at $1,289 is unconfirmed (deeper in a 50-unit listing), but visible Excellent copies start at $1,569 — the $280 gap is most likely grade tier, not a hidden defect.

One to watch tomorrow: Nikon Z 24-70mm f/4 S dropped $115 from $424 to $309 today, approaching ATL territory. 10 Grade at $309 is unconfirmed. If it holds or drops further on Day 2, it enters the list.

Not a deal today: Panasonic S5 II at $1,419 for Day 13. 11 At thirteen consecutive days without a move, $1,419 is the market's consensus value for a used S5 II, not a limited window.
