Why not put another $100ish and get new lens....I just don't get it
Actually about $250 if you check the official retail prices. http://www.bhphotovideo.com/c/product/112539-USA/Canon_2520A004_Telephoto_EF_135mm_f_2_0L.html
On top of this, with the refurbished warranty now matching the regular MFR's warranty (1 year) there's almost no real reason to "just" spend the extra $100/$250/whatever it is that the cost is. You're basically paying for a retail box, and a camera that is just as likely (okay, technically it's actually slightly more likely) to have issues than a refurbished camera.
*The reason why I believe a new camera is more likely to have issues than a refurbished camera is that a refurbished camera has already been given the factory once-over, and either was returned and refurbished to new for some reason, or didn't finish the original manufacturing process and had to be pulled from the line and adjusted/fixed before being considered finished. Thus, things get QC checked twice, compared to the once that normal retail gets.
Let get one thing straight, REBURB item DO NOT get treat special as many of you think.
Refurb. is defective item. PERIOD. NOT opened box or returned to customer changed mind.
Refurb. could be a simple broken cold solder joint in elec. circuit boards after 1-2yrs of use. Worst - broken parts that repaired with parts came from 3rd party vendors or contract manufacture(CM). NOT original parts that call out from Canon BILL OF MATERIAL(BOM)
Rather than getting sent through a QA process, they are fixed and hand tested to meet or exceed the quality of those which are sold as new. Canon has far too good of a reputation riding on their refurbished line to put 3rd party parts in their lenses. Further, I have dismantled the lenses I've purchased refurbished from them and the look as brand new on the inside as they do on the outside.
If you have not purchased a lens through their refurb program, you have no grounds to speak on for this debate. Please do refrain from getting up on a soapbox and stating your opinion as though it were fact, for it makes you look ignorant.
With 15yrs in mannufacturing, controlling CMs over sea...this method is currently been use in BIG companies. I should had said in my statement about 3rd party vendors, this is elec. 3 party vendor components. (capacitor, resistor, IC chip, SMT parts etc...)
I'll give you a hint: time = $. Putting more time to repair defective parts and sell for less is not how business operates. Today, big companies don't even try to trouble shoot in components level anymore. They replace PCB, WP levels.
Without knowledge in today manufacturing: "LEAN MANAFACTURING" & "SUPPLY CHAIN", your comments could make you look ignorant.
You mentioned, "I have dismantled the lenses I've purchased refurbished from them and the look as brand new on the inside as they do on the outside" ==> Unless you can indentify the original elec. components that were called out from Canon Bill of Material in MFG.
THE TRUE HURT, therefore, people don't like to hear it
It sure helps to be an electrical engineer chip designer in this situation where I can compare the components on the boards of the refurbished lenses to that of my new lenses...
You may know manufacturing tech (even though it obviously seems like you clearly do not), but this is not a debate on the widely accepted practice of refurbishing products. Unlike other companies, Canon does not do what you claim them to be doing. Making hasty generalizations about a specific company (Canon) which you have no experience with kinda makes you look ignorant.
Really, if you want to prove your right, pull apart the lenses and show the internal chip components are different. Plain and simple
