Measuring just 18mm in depth and weighing under 110 grams, it is renowned as one of the thinnest 35mm full-frame SLR lenses ever produced. Engineered with Asahi's famed Super Multi-Coating (SMC) for high contrast, color fidelity, and effective flare control. Providing a versatile 40mm focal length—often considered a true \"normal\" perspective on 35mm film—it offers an ideal compromise between 35mm wide-angle and 50mm standard views for street, documentary, and everyday travel photography. Native to all Pentax K-mount 35mm film SLRs (ME Super, MX, K1000, LX, etc.) and digital SLRs (K-1, K-3, K-70), and easily adapted to modern mirrorless systems (Sony E, Fujifilm X, Micro Four Thirds, Canon RF). Serial number 5138511. Complete with a rear K-mount cap.\u003c\/div\u003e\n\u003cbr\u003e\n\u003ch2 data-path-to-node=\"4\"\u003e\u003cb data-path-to-node=\"4\" data-index-in-node=\"0\"\u003eCondition\u003c\/b\u003e\u003c\/h2\u003e\n\u003cdiv\u003eOverall Condition: Excellent\u003c\/div\u003e\n\u003cbr\u003e\n\u003cdiv\u003eOptics are clear, fungus-free, and haze-free with a minor internal hair\/filament, which will not affect image performance.

Its ridiculously slim form factor transforms compact bodies like the Pentax ME Super or MX into practically pocketable 35mm setups. Due to its popularity with modern mirrorless camera adaptors and street photography enthusiasts, clean, scratch-free examples remain highly sought after on the secondary market.\u003c\/div\u003e\n\u003cbr\u003e\n\u003ch2 data-path-to-node=\"13\"\u003e\u003cb data-path-to-node=\"13\" data-index-in-node=\"0\"\u003eKeywords\u003c\/b\u003e\u003c\/h2\u003e\n\u003cdiv\u003eSMC Pentax M 40mm f2 8, Pentax 40mm Pancake Lens, Pentax K Mount Pancake, Vintage Pentax 40mm f2 8, Compact Pentax K Lens, Adapted 40mm Pancake Mirrorless\u003c\/div\u003e\n\u003cdiv\u003e\u003c\/div\u003e\n\u003cb data-path-to-node=\"17,2,0\" data-index-in-node=\"44\"\u003e\u003c\/b\u003e\n\u003c\/div\u003e","brand":"PENTAX","offers":[{"title":"Default Title","offer_id":49465471107414,"sku":null,"price":110.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0875\/5213\/1414\/files\/IMGP2171_b19abd6e-f086-47b5-be2d-e5c33071dd1d.jpg?v=1790603473","url":"https:\/\/colinscameras.co.uk\/products\/smc-pentax-m-40mm-f-2-8-pancake-lens-pentax-k-mount-with-both-caps-_395644400439_","provider":"Colins Cameras","version":"1.0","type":"link"}
