Manufactured between 1977 and 1985, it features a 6-element, 6-group optical design and Pentax’s renowned Super Multi-Coating (SMC) for improved contrast and flare resistance. With a 75° diagonal field of view and a minimum focus distance of 0.3m, it’s ideal for landscapes, architecture, and general-purpose shooting. This lens is engraved as “smc PENTAX-M 1:3.5 28mm” and is known for its excellent sharpness across the frame, even wide open.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cstrong\u003eCondition\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDusty internally, possible fungus dots\u003c\/li\u003e\n\u003cli\u003eAperture blades clean and snappy\u003c\/li\u003e\n\u003cli\u003eFocus ring smooth throughout range\u003c\/li\u003e\n\u003cli\u003eBarrel shows light cosmetic wear consistent with age\u003c\/li\u003e\n\u003cli\u003eMount clean and free from damage\u003c\/li\u003e\n\u003cli\u003eTested on digital body for functionality\u003c\/li\u003e\n\u003cli\u003eOverall condition: Excellent\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cstrong\u003eIncluded\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSMC Pentax-M 28mm F3.5 lens\u003c\/li\u003e\n\u003cli\u003eFront and rear caps \u003c\/li\u003e\n\u003cli\u003e\u003cbr\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cstrong\u003eCollectors Notes\u003c\/strong\u003e\u003cbr\u003eThis lens is the slower of the two M-series 28mm variants, prioritising sharpness and portability over speed. Often overlooked in favour of faster lenses, it’s a hidden gem for photographers who value precision and vintage character. Its compact size and low distortion make it a favourite among landscape and street photographers. Fully compatible with manual and aperture-priority modes on Pentax DSLRs, though it lacks an “A” setting on the aperture ring.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFocal length: 28mm\u003c\/li\u003e\n\u003cli\u003eMaximum aperture: F3.5\u003c\/li\u003e\n\u003cli\u003eMinimum aperture: F22\u003c\/li\u003e\n\u003cli\u003eLens mount: Pentax K\u003c\/li\u003e\n\u003cli\u003eFocus type: Manual\u003c\/li\u003e\n\u003cli\u003eOptical design: 6 elements in 6 groups\u003c\/li\u003e\n\u003cli\u003eDiaphragm: 5 blades, automatic\u003c\/li\u003e\n\u003cli\u003eMinimum focus distance: 0.3m\u003c\/li\u003e\n\u003cli\u003eFilter thread: 49mm\u003c\/li\u003e\n\u003cli\u003eDimensions: 63 × 31.5mm\u003c\/li\u003e\n\u003cli\u003eWeight: 180g\u003c\/li\u003e\n\u003cli\u003eCoating: Super Multi-Coating (SMC)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cstrong\u003eSEO Optimised Keywords\u003c\/strong\u003e\u003cbr\u003eSMC Pentax-M 28mm F3.5 lens, Pentax K mount wide angle, vintage Pentax lens UK, manual focus 28mm lens, Pentax M series prime, landscape lens Pentax, compact wide angle lens, Japan made Pentax lens, classic Pentax optics, Pentax film camera lens\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003c!--EndFragment --\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"PENTAX","offers":[{"title":"Default Title","offer_id":51205882904918,"sku":null,"price":49.5,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0875\/5213\/1414\/files\/IMGP8469_9d1b4b34-ab84-4529-b56f-328c7656586c.jpg?v=1787657576","url":"https:\/\/colinscameras.co.uk\/products\/smc-pentax-m-28mm-f-3-5-wide-angle-lens-pentax-k-mount","provider":"Colins Cameras","version":"1.0","type":"link"}
