I have a collection of old Canon EF lenses that I no longer use and I'm looking to sell them to free up some cash and clear out space. What are the best online marketplaces or platforms to list and sell used EF lenses?

I have about 5-6 EF lenses in total, ranging from a 50mm f/1.8 prime to a 70-300mm zoom. The lenses are in good used condition - fully functional with normal signs of wear but no major damage. I still have the original boxes and front/rear caps for most of them.

Some key considerations for me:

1. Reaching serious buyers - I want exposure to real photography enthusiasts and pros who will appreciate the value and utility of these EF lenses. Where do knowledgeable Canon shooters tend to shop for used gear online?

2. Pricing guidance - What's the best way to determine fair market prices for each lens based on the specific model, condition, and included accessories? I don't want to overprice them and get no interest, but I also don't want to undervalue them.

3. Seller protections - I've never sold camera gear online before, so I want to use reputable sites that protect me as a seller in case of scams, fraud, chargebacks, etc. Which platforms are known for having good seller protection policies and systems in place?

4. Reasonable selling fees - Obviously the online marketplaces will take a cut of each sale, but I'd like to keep more of the proceeds in my pocket. What kind of selling fees can I expect from the major options out there? Are the fees worth the services and exposure they provide?

5. Smooth transactions - Ideally I'd like the process of listing, selling, getting paid, and shipping to be as easy and painless as possible as a casual seller. Which sites offer the most user-friendly and streamlined workflows for one-off sales?

I've heard of people having success selling lenses on eBay, Facebook Marketplace, Fred Miranda forums, and KEH. But I'm open to any other suggestions for online channels that have worked well for this purpose.

My goal is to get these lenses into the hands of photographers who will use and enjoy them, while getting a decent and fair return that makes the effort of selling online worth it. I'd appreciate any insights from other photographers or folks with experience selling photo gear online. Where have you had the best results and smoothest experiences as a seller? Any particular marketplaces or approaches you'd steer me towards (or away from)?

Thanks in advance for your advice! I'm looking forward to clearing out my unused lenses and hopefully making a few bucks in the process. Just want to make sure I go about it the smart way by choosing the right online sales channels. Let me know what's worked for you!
