We charge only a 5% commission. One of the more popular used gear for sale sites charges a minimum of 20%. Plus assorted fees! Yikes. The minimum item price here is $500 (or less for a $25 fee). If you are interested please <a href=\"mailto:samandmayasgrandpa@att.net\">e-mail<\/a><\/center> with the words Items for Sale Info Request cut and pasted into the Subject line :). Stuff that is priced fairly&#8211;I offer free pricing advice, usually sells in no time flat. In the past few months, we have sold just about everything in sight. Do know that prices on some items like the EOS-1D Mark IV, the old Canon 500mm, the EOS-7D, and the original 400mm IS DO lens have been dropping steadily. Even the prices on the new 600 II and the 200-400 with Internal Extender have been plummeting. You can see all current listings by clicking <a href=\"https:\/\/www.birdsasart-blog.com\/baa\/used-photography-gear-for-sale\/\">here<\/a> or by clicking on the Used Photo Gear tab on the right side of the yellow-orange menu bar above. <\/p>\n<h2><strong>Unsolicited, via e-mail, from Gerry Keshka<\/strong><\/h2>\n<p>Hi Artie, I wanted to share how much I appreciate your Used Gear \u201cservice.\u201d You have posted how you help sellers, but the other side of the equations is how much this service helps buyers.   I have purchased three lenses (Canon 200-400, 500 f4 II, and 70-200 F2.8) all lovely experiences and I saved almost $5K over retail.  Each of the sellers was delightful, willing to help me assess if the purchase was right for me by sharing their experience with the lens.  Each lens was in the condition advertised (or better), and typically included several \u201cadd-ons\u201d that would have cost several hundred dollars. <\/p>\n<h3>Recent Successful Used Gear Sales<\/h3>\n<ul>\n<li>Mike Kaplan sold a Canon EOS 7D Mark II in near-mint condition for $925 to a buyer who contacted him on day one when the body was listed in early March. <\/li>\n<li>Sue Sanborn sold her Canon 300mm f\/2.8L IS II USM lens in near-mint condition for $4100 in early March.

It is fast and sharp. I used mine as my workhorse lens (along with the old 600mm f\/4) for almost ten years to photograph birds and wildlife all over the world. Both have been replaced for me by their far more costly version II counterparts. The 500 f\/4s have long been the world\u2019s most popular super-telephoto lenses for wildlife and sports. With these lenses selling quite well the demand for a near-mint copy should be high so best to act quickly if you think that this lens has your name on it.<\/em> artie<\/p>\n<table>\n<tr>\n<td>\n<p><center>ngg_shortcode_0_placeholder<\/center><\/p>\n<\/td>\n<\/tr>\n<tr>\n<td>\n<p>This image was created on the Mini Gatorland IPT with the hand held <a href=\"https:\/\/www.bhphotovideo.com\/c\/product\/1092632-REG\/canon_9524b002_ef_100_400mm_f_4_5_5_6l_is.html\/BI\/6633\/KBID\/7226\/kw\/CA1004002LIS\/DFF\/d10-v2-t1-xCA1004002LIS\" target=\"_blank\">Canon EF 100-400mm f\/4.5-5.6L IS II USM lens<\/a> and the <a href=\"https:\/\/www.bhphotovideo.com\/c\/product\/732113-USA\/Canon_4409B002_Extender_EF_1_4X_III.html\/BI\/6633\/KBID\/7226\/kw\/CA14XEF3\/DFF\/d10-v2-t1-xCA14XEF3\" target=\"_blank\">Canon Extender EF 1.4X III<\/a> (at 520mm) with the rugged, blazingly fast <a href=\"https:\/\/www.bhphotovideo.com\/c\/product\/1221604-REG\/canon_0931c016_eos_1d_x_mark_ii.html\/BI\/6633\/KBID\/7226\/kw\/CAE1DX2K\/DFF\/d10-v2-t1-xCAE1DX2K\" target=\"_blank\">Canon EOS-1D X Mark II.<\/a> ISO 800.
