That number is not published for the 12-45mm F4.0 PRO, the 40-150mm R, or the 17mm F1.8 II.<\/p><\/div>\n  <div class=\"faq-item\"><h3>When the 14-42mm III is listed to ship<\/h3><p>The OM SYSTEM US product page lists it at $349.99 as a preorder and says it ships mid October. The box list on that page is the lens, an LC-46 cap, an LR-2 rear cap, and a manual.<\/p><\/div>\n  <div class=\"faq-item\"><h3>Whether the 40-150mm R page lists weather sealing<\/h3><p>It does not. The 12-45mm F4.0 PRO and the 14-42mm III pages both list IPX1, which is the same class as the PEN body. The 40-150mm R spec block lists diameter, length, weight, and closest focus, and no weather rating.<\/p><\/div>\n  <div class=\"faq-item\"><h3>What 12 mm and 14 mm cover on this camera<\/h3><p>The sensor is 17.3 \u00d7 13.0 mm. OM SYSTEM converts 12 mm to a 24 mm equivalent and 14 mm to a 28 mm equivalent. The 12-45mm therefore starts wider than the 14-42mm III, and the 40-150mm R starts at an 80 mm equivalent.<\/p><\/div>\n  <div class=\"faq-item\"><h3>Why the 17mm F1.8 II stays off the default kit<\/h3><p>It is 112 g and 37.6 mm long, at F1.8, for a 34 mm equivalent. That is a single angle of view. The travel kit here is a zoom that changes angle, which is the 12-45mm at F4 or the 14-42mm III at F3.5\u20135.6.<\/p><\/div>\n<\/div>\n\n<h2>Final Verdict<\/h2>\n<div class=\"conclusion-module verdict-box\">\n  <div class=\"verdict-picks\">\n    <div class=\"verdict-item\">\n      <span class=\"verdict-label\">\ud83c\udfc6 Best Overall:<\/span>\n      <div class=\"verdict-product\"><strong>M.Zuiko Digital ED 12-45mm F4.0 PRO<\/strong> <span class=\"verdict-reason\">\u2013 254 g, 70 mm, F4 from 24 mm to 90 mm equivalent.<\/span><\/div>\n      <a href=\"https:\/\/www.amazon.com\/s?k=M.Zuiko+Digital+ED+12-45mm+F4.0+PRO&#038;tag=e6890-20&#038;linkCode=osi\" target=\"_blank\" class=\"verdict-btn\" rel=\"nofollow noopener\">Buy Now<\/a>\n    <\/div>\n    <div class=\"verdict-item\">\n      <span class=\"verdict-label\">\ud83d\udc8e Best Value:<\/span>\n      <div class=\"verdict-product\"><strong>M.Zuiko Digital 14-42mm F3.5-5.6 III<\/strong> <span class=\"verdict-reason\">\u2013 125 g, IPX1, and the lens in the 5.5-stop test, listed at $349.99.<\/span><\/div>\n      <a href=\"https:\/\/www.amazon.com\/s?k=M.Zuiko+Digital+14-42mm+F3.5-5.6+III&#038;tag=e6890-20&#038;linkCode=osi\" target=\"_blank\" class=\"verdict-btn\" rel=\"nofollow noopener\">Buy Now<\/a>\n    <\/div>\n    <div class=\"verdict-item\">\n      <span class=\"verdict-label\">\ud83d\udcb0 Budget Pick:<\/span>\n      <div class=\"verdict-product\"><strong>M.Zuiko Digital ED 40-150mm F4.0-5.6 R<\/strong> <span class=\"verdict-reason\">\u2013 190 g, an 80\u2013300 mm equivalent, listed from $169.99.<\/span><\/div>\n      <a href=\"https:\/\/www.amazon.com\/s?k=M.Zuiko+Digital+ED+40-150mm+F4.0-5.6+R&#038;tag=e6890-20&#038;linkCode=osi\" target=\"_blank\" class=\"verdict-btn\" rel=\"nofollow noopener\">Buy Now<\/a>\n    <\/div>\n  <\/div>\n  <p class=\"verdict-summary\">The M.Zuiko Digital ED 12-45mm F4.0 PRO is the travel zoom that starts at a 24 mm equivalent and holds F4, at 254 g and 70 mm.
