MFT enters the chat: OM-1 $1,039 and 4 more lows

The OM System OM-1 (Micro Four Thirds, or MFT — the compact sensor format shared by OM System and Panasonic) has not appeared in this radar before. Today it does, with a signal that's hard to ignore: 42 units at $1,039 on MPB, which is 53% off its $2,199 MSRP. That volume at that price doesn't come from individual sellers trading in their kits. It reads as a structural clearance — the kind that follows an announced successor. The OM-1 II is out. The first-generation body is being flushed.

Sony E-mount is the second story, same as yesterday: the A7R VI launched in May 2026 and the cascade is still running. The A7R V and A7 IV are both at or near six-month lows, with inventory levels at 97 and 174 units respectively on MPB — that second number is well above the 40–60 range that represents normal used-dealer turnover. Fujifilm X appears to have exhausted its drop cycle: the X-T4 is holding at $949 with no further movement.

Nikon Z is entering a floor-formation phase. The Z5 has now sat at $679 for three consecutive days — not a flash price, but a market consensus forming.

Why it's low now: The OM-1 II has been released, and the trade-in wave is here. At $1,039, the original OM-1 is 53% off its $2,199 MSRP. 1 Forty-two units on MPB at this price is a structural clearance, not individual seller activity. A healthy used listing for a niche body like this runs 5–15 units. Forty-two is a signal.

The OM-1 (20.4MP MFT sensor, IP53 weather sealing, computational subject-tracking AF, 50fps electronic shutter, in-body stabilization rated to 7 stops with compatible lenses) launched in early 2022 at $2,199. The OM-1 and OM-1 II share the same sensor and chassis; the Mark II adds improvements to subject recognition and live ND capability via firmware. At $1,039 versus the OM-1 II's roughly $2,199 street price, you are paying half the money for approximately 90% of the capability. For wildlife photographers, macro shooters, and travel photographers who've been priced out of MFT system entry, this is the inflection point.

Shutter count: MPB does not disclose shutter count in listing metadata. The OM-1's mechanical shutter is rated for approximately 200,000 actuations. Contact MPB support before checkout and request the count for your specific unit — at 42 units in stock, you have room to be selective.

Condition: MPB Good — functional with light cosmetic wear. Verify that port covers (weather sealing) are intact when reviewing condition notes.

Red flags: No known OM-1 batch defects at any serial range. The main exposure is the now-superseded generation status, which is already priced in.

Seller: MPB (6-month warranty, 7-day returns, Trustpilot Excellent).

Pull trigger or wait: High confidence buy. Forty-two units can move faster than the daily pricing cycle refreshes. $1,039 is the lowest dealer price this body has reached. If you've been MFT-curious, this is the entry point that changes the math.

Pair it with: Panasonic Leica DG Vario-Elmarit 12-60mm f/2.8-4 ASPH (24–120mm equivalent, weather-sealed) — the all-in-one standard zoom for MFT. Current used pricing for this lens on MPB was not confirmed in this research run; check MPB directly before assuming availability.

Why it's low now: The A7R VI launched in May 2026 at $4,498, and sellers upgrading are flooding the used market. MPB currently lists 97 A7R V bodies, with the floor at $2,469 — a 6-month low, and $301 below the $2,770 B&H Used price recorded on May 24. 2 The A7R V (61MP BSI CMOS, 8-stop IBIS, AI-based subject tracking, 4K/60p oversampled output) remains the highest-resolution full-frame Sony body readily available in the used market.

Further downside is plausible — 97 units is a large pool, and A7R VI early adopter trade-ins will keep feeding it through June. The probable floor over the next 30–45 days is $2,200–2,300 if the pattern holds. For users who need 61MP with dealer warranty now, $2,469 is a defensible entry.

Shutter count: MPB does not disclose. The A7R V's mechanical shutter is rated for 500,000 actuations; request the count for your specific unit before checkout.

Red flags: No model-level defects at any known serial range.

Seller: MPB (6-month warranty).

Pull trigger or wait: High confidence buy if you need 61MP now. If your timeline is flexible, waiting until late June could yield another $150–200 off — 97 units means you're not racing inventory.

Pair it with: Sony FE 85mm f/1.8 — currently $149 on MPB with 50 units in stock, 75% off MSRP $598. 3 At 61MP, the FE 85mm f/1.8 delivers strong portrait resolving power at a price that requires no real deliberation.

Why it's low now: The A7 IV (33MP BSI CMOS full-frame, 10fps, 4K/60p, E-mount) sits at $1,689 on MPB with 174 units in inventory — a supply-side anomaly. 4 Normal used-dealer turnover for a body at this tier runs 40–60 units. The A7 IV has no announced successor, but it's caught in the A7R VI spillover and the broader Sony E-mount trade-in cycle. $1,689 is the current floor and likely a 6-month low.

One hundred seventy-four units of uncleared supply argues for price drift continuing into June. If you're not in a hurry, the realistic scenario is an additional $50–100 off by mid-June as units churn.

Shutter count: Undisclosed. The A7 IV's mechanical shutter is rated for 500,000 actuations. A unit with a disclosed count under 20,000 is worth a modest premium over floor pricing.

Red flags: No model-level defects at any known serial range.

Seller: MPB (6-month warranty, 7-day returns).

Pull trigger or wait: Buy, or wait 2 weeks. $1,689 is a real price on a 33MP full-frame body with dealer warranty. If you find a low-shutter-count unit, don't wait — pull the trigger. If counts are undisclosed and you're budget-sensitive, 174 units of supply gives you the luxury of patience.

Pair it with: Sony FE 24-105mm f/4 G — currently $444 at MPB with 67 units in stock. 5 An A7 IV at $1,689 plus the 24-105mm f/4 G at $444 gives you a 33MP full-frame travel kit for $2,133 — well below the A7 IV body's own $2,499 MSRP new.

Why it's low now: Three consecutive days at $679 is not a flash price. 6 The market has found a clearing price. The Z5 (24.3MP full-frame Z-mount, 5-axis IBIS, dual UHS-II SD slots) launched at $1,396.95; at $679, that's 51% off. Twenty-four units are currently available. This is the first full-frame Z-mount body to sustain a sub-$700 price at a credentialed dealer in this research window.

Known trade-offs: 4.5fps burst, and a sensor that loses measurably to the Z6 III in low-light conditions. What you're buying is full-frame image quality and Z-mount access at a price where APS-C was the only credentialed option until recently.

Red flags: No Z5 batch defects at any known serial range. If your existing glass is Nikon F-mount, budget $99–$150 for the FTZ II (F-to-Z) adapter.

Seller: MPB (6-month warranty, Trustpilot Excellent).

Pull trigger or wait: High confidence buy. Three days of price stability with 24 units in stock — this is a confirmed floor. Full-frame Z-mount below $700 is a real threshold.

Pair it with: Nikon NIKKOR Z 40mm f/2 — a compact 60mm-equivalent pancake prime for full-frame. Used pricing on MPB typically runs $180–$200 at Good grade. A Z5 plus the Z 40mm f/2 lands around $860–$880 total — a full-frame mirrorless kit for under $900.

Why it's low now: The Z50 II (APS-C DX Z-mount, 20.9MP, EXPEED 7 — the same processor generation as the Z9 and Z8) launched in late 2024 at $909 MSRP. 7 MPB currently has 18 units at $884 — $25 below MSRP, a new price low for this body.

"$25 below new" doesn't sound dramatic. The actual value is MPB's 6-month warranty plus return policy on an $884 purchase — coverage that gray-market or third-party online sellers at similar prices don't offer. The Z50 II's EXPEED 7 autofocus performance (substantially ahead of the original Z50's EXPEED 6, particularly for subject tracking) makes this a current-capability body, not a clearance-bin compromise. At under 6 months old in the used market, units are expected to carry low shutter counts — likely under 5,000 across the 18 available.

Red flags: No model-level defects at any known serial range. The Z50 II is Z-mount DX — compatible natively with DX Z lenses and with full-frame Z lenses (cropped field of view). F-mount glass requires the FTZ II adapter.

Seller: MPB (6-month warranty).

Pull trigger or wait: Buy. $25 under MSRP with a 6-month warranty on a current-production APS-C camera is a clean deal. If budget is the limiting factor, the gap between used and new will likely widen over the next 60 days as early buyers continue cycling out.

Pair it with: Nikon NIKKOR Z DX 16-50mm f/3.5-6.3 VR — the standard Z50 kit zoom. Used on MPB, this lens typically runs $80–$120 at Good grade. A Z50 II plus the 16-50mm VR comes in under $1,000 total — a current-model mirrorless APS-C travel kit for four figures.
