honestly im just so fed up with how expensive canon glass is still like i bought this R6 Mark II a year ago and im still stuck with the kit lens for my wildlife stuff which is just terrible for birds tbh. my logic was that by 2026 the prices would finally drop or wed see some actual deals but everything is still so pricey and i cant keep carrying this heavy adapter for my old EF glass. so i was thinking maybe cyber monday is actually gonna have something good this year or am i just dreaming? i really need that 100-500mm but my budget is maxed out and im kinda ready to just sell it all and go sony if these sales suck again... anyone got any predictions?
Honestly, I wouldn’t hold my breath for some massive Cyber Monday miracle from Canon—they’ve basically got us over a barrel with that proprietary mount and they know it. Everyone keeps hyping up the Canon RF 100-500mm f/4.5-7.1 L IS USM like it’s the holy grail of birding glass, but when you look at the actual price-to-performance ratio, it’s kind of a joke compared to what’s happening in the E-mount world. I mean, sure, it’s sharp—wait, no, it’s incredibly sharp—but is it 'second mortgage' sharp? I really don't think so. Most of those glowing reviews are just echoing the same marketing points, while actual owners are still complaining about the slow aperture at the long end. If you want to actually save some money instead of waiting for a tiny $150 discount that won't even cover your insurance, here are my two cents:
^ This. Also, so funny you ask this — last year I was in your exact position with my R6. I spent months waiting for a massive Cyber Monday drop on the Canon RF 100-500mm f/4.5-7.1 L IS USM that never came. I eventually grabbed the Canon RF 100-400mm f/5.6-8 IS USM for under $600 during a flash sale. It is not L-series glass, but for the price difference, it performs well for hobbyist birding in good light. If you need reach, the Canon RF 800mm f/11 IS STM usually hits deep discount levels in November. Before you jump ship to Sony, what specific birds are you shooting? If you are mostly doing low-light forest photography, these slower budget lenses might not solve your frustration regardless of the price.
@Reply #1 - good point! The refurbished store is the only place where prices are grounded in reality. Everyone hypes the L-series zooms, but real owners know the slow apertures at the long end are a major compromise for the price. What is your actual dollar limit? "Maxed out" is too vague for a specific recommendation. Consider these alternatives:
