Very true, which is why Canon (and most other advertising claims) are careful to use the caveat “up to”.With those numbers, anecdotes only get you so far.
This is an nice resource for checking out how other users fared with their shutter counts:
Canon's numbers are no exact counts at which the camera will fail, but just estimates of what consumers can reasonably expect.
I'm using 95mm slim, clear protection filter, Mfg. by Ice, purchased on Amz and am able to use with both filter installed, lens cap attached and hood fits easily over my 800 lens, in either position, Alan. Priced at under $20.00, I had my doubts and was skeptical about the quality of this filter but have been impressed with the metal filter rim and glass, so far. Could it just be your filter brand and/or size? Do you have a friend with a 95mm filter different than yours that you might try? Good luck.As I wrote, the JJC hood didn't fit over the 95mm filter on mine. Maybe it needs a slim fit filter. Was yours a very tight fit?
AF is not what I am looking for. 14mm with movements is.I’m not sure I see the benefit of AF in a TS lens. For me, at least, the ability to use a rear filter is more benefit. But the extra 3mm would also be useful.
Wow...amazing.We have to keep receipts on our gear ready to show the customs, even for old gear, if you can’t prove you didn’t buy it while traveling you can be forced to pay the taxes on retail Norwegian price (again). Luckily it’s not like they have resources to really pick you out and follow through, but it happens.
I'd say the price was correct for the launch, given that the lens is still on backorder in major shops.Did no one post any reviews of this. The price is just too much, would buy an EF one and adaptor.
Hi Rick,Yes John, that is a great point!
Hard to beat B&H with the generous returns and Payboo discounts!
Thanks for the info!

Interesting point. Photo-oxidation is the major source of degradation of plastics. So, an f/8 lens with an internal plastic element that is not in use 24/7 should last a good few years.Hi all, I'm new here but a regular reader on this site. From the graphs the RF 100-400 looks to have a bit less contrast and sharpness than the EF 100-400 and RF 100-500, looks quite promising despite f/8 aperture.
Surprisingly, one thing that nobody has mentioned is the PMo (plastic-molded) aspherical lens element.
We've also recently seen the use of a molded plastic aspherical lens element in the RF 50mm f/1.8.
This seems like a strange trend in new Canon RF lenses, considering that PMo aspherical lens element were reserved for cheap kit lenses in the past. The next level of lenses used molded glass aspherical elements, with ground glass aspherical lens elements being the mainstay in L-series glass from what I can figure.
Scouring the internet, I can only find the following Canon lenses which utilise pMo aspherical elements:
This lens looks so much like a full frame version of the EF-S 55-250mm IS STM, (which provides the crop equivalent of 88-400mm @ F9). Even though Canon was so miserly as to not even put a metal lens mount on that lens, its optics were really good, and from what I can ascertain, this lens had no PMo elements. This lens also had no sealing, so it wasn't dust proof and drip proof either.
- Canon EF-S 18-200mm f/3.5-5.6 IS - one PMo (precision molded) aspherical element
- Canon EF-S 18-135mm f/3.5-5.6 IS STM - one PMo (precision molded) aspherical element
- Canon EF-S 18-135mm f/3.5-5.6 IS USM - one PMo (precision molded) aspherical element
- Canon EF-S 10-18mm f/4.5-5.6 IS STM - two aspherical lens elements, one is a high-precision large-diameter PMo (Plastic-Molded) lens.
- Canon EF-M 15-45mm f/3.5-6.3 IS STM - three aspherical elements, one is glass-molded and the other two are precision molded,
- RF 50mm f/1.8 STM - one precision molded optic (PMO) aspherical element
- Canon RF 100-400mm F5.6-8 IS USM - one precision molded optic (PMO) aspherical element

Plastic-molded (PMo) aspherical lens elements
PMo aspherical lens elements are formed by injecting resin into an aspherical surface mold. Highly suitable for mass production, they play a major role in improving the image quality of entry-level lenses, such as the EF-S10-18mm f/4.5-5.6 IS STM (released in 2014), which need to be kept relatively affordable. Resin is injected into a high-precision mold that takes the shape of an aspherical lens. After the lens element is separated from the mold, coatings are added to finish the lens.
Trying to find the life expectancy of optical resins proved frustrating. I've yet to hear of an optical plastic as durable as glass., and I suspect that all plastics degrade over time, and won't have the life expectancy of molded or ground glass elements. I've had a Canon EF-S 10-18mm for many years, and the optics are still good. Perhaps only time will tell if or when these resins decrease in optical clarity as they age.
I'm not sure what this trend indicates. Is it cost cutting to increase profits, or is Canon cutting back on its construction of 'budget' lenses, even more so than in the past?
Looking forward to seeing how the RF 100-400mm compares against the EF 100-400mm II, RF 100-500mm and even the EF-S 55-250mm. Then we'll know what kind of image quality, construction and durability we're getting for our money ($649 USD, £699, 730 €, $1,200 AUD).
My EF 400 2.8 L IS II doesn't get near the FPS in mechanical shutter as my RF 28-70 f2L and the 400 isn't all that old. If you think all of your old EF lenses are going to work perfectly on the R3 you're delusional because it's physically impossible due to the lack of electrical contacts compared to the RF's.
They were significantly cheaper than Canon ones when I bought them, but I've also changed to going Canon-only for batteries, so I haven't monitored the pricing.I looked the price of the Hahnel batteries up here in the UK and I was surprised to see that they are pretty close to the genuine Canon ones in price. For my 'work' cameras I've always used genuine Canon batteries.
that's always been the case.. likely due to reverse engineering.Yes, *any* EF lens should work fine on RF mount cameras, using the Canon adaptor. At least, that’s the theory.
In practice, some will acquire focus as rapidly as Canon glass, but others will be slower and more hesitant, due to heavy elements and/or less efficient focus motors.
Tracking subjects across the frame, at a near-constant distance, should theoretically be as good as with Canon glass, as it is dependent on Canon’s tracking algorithms, rather than an ability to refocus. However, AF and tracking both utilise cross-talk between chips in the *lens* as well as the body, so third party lenses may not track quite as efficiently, especially when using eye-AF.
