Canon RF breaks $1,000, OM-1 final hours: 5 lows

The OM System OM-1 fire sale is entering its closing window. Forty-two units were available on MPB when yesterday's radar went out; as of this morning's check, that count has dropped to 10+. Roughly 32 units moved in 13 hours — a burn rate of about 2.5 bodies per hour. 1 The price floor of $1,039 (53% off MSRP $2,199) has held. When the remaining units go, the window closes.

Sony E-mount pushed a new low overnight. The A7 IV — which sat at $1,689 with 174 units yesterday — slid another $60 to $1,629, extending the 6-month floor with 175 units now in stock. 2 The A7R VI cascade is still pulling the entire A7 line down.

Canon RF produced the sharpest single-day drop in this window: the RF 24-105mm f/4 L IS USM fell $125 in 24 hours, crossing below $1,000 for the first time at $904. 3 L-mount lands its stealth entry: the original Panasonic Lumix S1R at $1,339 (64% off its $3,699 MSRP) has 3 units on MPB — a high-resolution full-frame sleeper that doesn't advertise itself. 4 The Nikon Z5 holds its floor for the fourth consecutive day. Leica M and Fujifilm X produced no new actionable moves.

6-month range: $1,039–$2,199 (current price equals 6-month floor; body launched at $2,199 MSRP in early 2022) 1

Why it's low now: The OM-1 II is out and MPB is clearing the original. Structural cascade — same as the A7R V/VI pattern. What's unusual here is the velocity: 32 units moved in 13 hours. Normal clearance for a niche MFT flagship runs 3–5 units a day. This is 2.5 per hour.

The OM-1 is a 20.4MP stacked MFT sensor body with IP53 weather sealing, 50fps electronic shutter, and IBIS rated to 7 stops in conjunction with sync-IS-compatible lenses. The stacked sensor — not a conventional BSI — is why the OM-1 held its price as long as it did. At $1,039, you're getting a weather-sealed, burst-capable wildlife body for roughly what a Sony A6700 APS-C body sells for on the used market.

Shutter count and condition: MPB does not surface shutter count on the search page. The OM-1's mechanical shutter is rated at approximately 200,000 actuations. Contact MPB support and request the count for your unit before checkout — with 10+ units remaining, you still have some selection latitude. At this burn rate, that window may close within 4–6 hours of publication.

Red flags: No known batch defects or serial-range recalls at any OM-1 production run. Confirm that port covers (rubber gaskets for weather sealing) are undamaged in the condition notes.

Pull trigger or wait: High confidence buy. At 10+ remaining units and 2.5 units/hour velocity, the timing window is short. $1,039 is the confirmed 6-month low. For MFT shooters or anyone who has been curious about the system, this is the entry point that resets the cost-per-capability math.

Pair it with: Panasonic Leica DG Vario-Elmarit 12-60mm f/2.8-4 ASPH. OIS, weather-sealed, covers a 24–120mm equivalent range on MFT. Check MPB directly for current pricing before committing.

6-month range: $1,629–$2,499 (today's $1,629 is a new 6-month floor; was $1,689 as recently as May 25) 2

Why it's low now: The A7 IV dropped $60 overnight — 3.6% in 13 hours — while inventory actually grew by one unit to 175. That combination (price down, unit count up) is a supply-pressure signal. The A7R VI launched in May 2026 and generated a large wave of A7-series trade-ins; the overflow is compressing everything below the A7R V on the E-mount ladder.

The A7 IV is a 33MP full-frame BSI CMOS body with 10fps, 4K/60p, real-time eye tracking, and dual card slots (CFexpress A + SD). At $1,629 from MPB with a 6-month warranty, it's $870 below its $2,499 MSRP new.

Shutter count and condition: The lowest-priced A7 IV units at $1,629 are likely MPB Good grade — functional with light cosmetic wear, not the Like New units shown at the top of the default sort. 5 Like New units with documented shutter counts of 1,508–6,595 are available from $1,829 upward. The A7 IV's mechanical shutter is rated for 500,000 actuations. A Good-grade unit at $1,629 with shutter count under 30,000 is a strong value; request confirmation before checkout.

Red flags: No model-level defects or recall events at any A7 IV serial range.

Pull trigger or wait: Buy, or wait 2 weeks. $1,629 is a real 6-month low on a 33MP full-frame body. If you find a Good or better unit with a disclosed shutter count under 30,000, pull the trigger — that's the unit worth moving on. If you're indifferent to the extra $60 in potential savings and can wait, 175 units of inventory argues for continued price drift.

Pair it with: Sony FE 50mm f/1.8 — currently $142 at MPB with 10+ units in stock. 6 A7 IV plus FE 50mm f/1.8 lands at $1,771 — a full-frame kit with dealer warranty for under $1,800.

6-month range: $904–$1,200+ (today's $904 is the first time this lens has crossed below $1,000 on the used market at a credentialed dealer) 3

Why it's low now: The RF 24-105mm f/4 L IS USM dropped $125 overnight — a 12.2% single-day decline — to land at $904. The RF ecosystem is absorbing a surge of EF→RF migration trade-ins: shooters who held EF glass through the adapter for years are converting, and the lenses they're trading in are compressing entry-level RF glass pricing. The $1,000 psychological threshold matters here; once a lens crosses it, a new buyer tier enters the market.

The RF 24-105mm f/4 L IS USM is Canon's standard zoom for the RF system — 5-stop IS, L-series weather sealing, nano USM focusing. For RF-mount Canon shooters, it is the do-everything travel and event zoom. The EOS R5 and R6 II kit this lens. At $904 used versus $1,349 new, the used discount is $445.

Shutter count and condition: Lens — no shutter count applicable. Check that IS is functional and that autofocus is responsive across the zoom range. MPB's Good grade on lenses indicates cosmetic marks but optically clear elements.

Red flags: No known decentering issues at the model level. Individual unit QC varies — confirm IS stability and no rattling of elements in the MPB condition notes.

Pull trigger or wait: High confidence buy. First sub-$1,000 price at a dealer for this lens. The EF→RF migration surplus is structural, not cyclical — prices are unlikely to snap back. Whether this becomes the new floor or drifts further to $850 over the next 30 days is uncertain; $904 is not a price that requires timing.

Pair it with: Canon EOS R8 — the entry RF body. Used R8 prices have been tracking around $950–$1,050 on r/photomarket in recent weeks. RF 24-105mm f/4 at $904 plus an R8 at that range gives you a weather-sealed, full-frame RF kit for under $2,000.

6-month range: $1,339–$3,699 (MSRP was $3,699 at launch; $1,339 represents a 64% discount) 4

Why it's low now: The S1R was Panasonic's first-generation L-mount high-resolution body, launched in 2019 at $3,699. The S1R II launched in 2025, rendering the original deeply discounted. Three units are available on MPB at $1,339–$1,379. This is the cheapest path to a 47.3MP full-frame L-mount sensor with in-body stabilization (6 stops, 5.5 stops confirmed by CIPA) and Dual Native ISO at any credentialed dealer.

The S1R uses a 47.3MP BSI CMOS sensor — higher resolution than the Sony A7R V at 61MP? No. But at $1,339 versus the A7R V's $2,469, the S1R is 46% cheaper and still delivers files that exceed most print requirements at any size up to roughly 24×36 inches. The L-mount ecosystem (Sigma, Leica, Panasonic, plus Sigma's cine-origin adapted glass) is smaller than E-mount but credible. Anyone already invested in L-mount glass — or considering Sigma Art primes — should stop here.

Shutter count and condition: Only 3 units available. The S1R's mechanical shutter is rated for 400,000 actuations. This is a 2019 body; expect shutter counts in the 20,000–80,000 range. Request the count before ordering. At $1,339, even a 60,000-actuation unit has significant life remaining.

Red flags: No batch defects or recalls at any known S1R serial range. The body is now 7 years old; confirm that the OLED viewfinder and rear LCD are functional and that the sensor is clean. MPB's warranty covers functional defects.

Pull trigger or wait: Buy. Three units is not a moat — if the specific count and condition check out, move. The 64%-off price reflects a first-generation body against a second-generation market, not a defect signal. L-mount shooters have been waiting for S1R prices to crack $1,500; at $1,339, they have.

Pair it with: Sigma 45mm f/2.8 DG DN Contemporary (L-mount) — a compact, lightweight street and travel prime for the S1R's 47MP sensor. Check MPB for current used pricing.

6-month range: $679–$1,099 (current price equals confirmed 6-month floor; fourth consecutive day at $679) 7

Why it's low now: Day four at $679. When a used-dealer price holds for four consecutive days on a 26-unit pool, that is a floor — a price where supply and demand have equilibrated. The Z5 (24.3MP full-frame Z-mount, 5-axis IBIS, dual UHS-II SD slots) launched at $1,396. At $679, that is 51% off. The Z5 II lists at $1,519 on MPB — a $840 premium over the Z5. The Z5 II's advantages are EXPEED 7 autofocus and 4K/30p (versus the Z5's 4K/30p via crop, 24fps effectively). If autofocus tracking is not your primary use case, the Z5 at $679 returns far more sensor capability per dollar.

One SKU verified: MPB unit 3852908, Good grade, 3,273 shutter actuations, 6-month warranty. 7 The Z5's mechanical shutter is rated for 200,000 actuations; 3,273 is essentially new.

Red flags: No batch defects at any Z5 serial range. If you hold Nikon F-mount glass, add $99–$150 for the FTZ II adapter.

Pull trigger or wait: High confidence buy. Four-day price floor, low-actuation units confirmed, full-frame Z-mount below $700. Sub-$700 full-frame mirrorless with dealer warranty has not existed on this radar before the Z5 established this level. The logical next step down from here is the Z5 II approaching $1,000 used — a different market.

Pair it with: Nikon Z 40mm f/2 — currently $179–$204 at MPB with 10+ units in stock. 8 Z5 at $679 plus Z 40mm f/2 at $179 = $858 full-frame mirrorless kit. The Z 40mm f/2 covers a 40mm field of view on Z-mount full-frame — compact enough for street and travel, fast enough for indoor available light.
