Canon Q3 Operating Profit Drops 10%, Forced to Lower Full-Year Forecast

Canon released its third-quarter financials today, and the results are generally good for Canon Corp. Canon did suffer an operating profit drop from a year ago's third quarter, but as they noted that the 3rd quarter of 2024 was a bit of an outlier, as it was their highest quarter in history. So, a drop […]

All computer RAM and SSD prices to go up 30%

If you're thinking about buying new RAM for your computer, new SSDs, or even just new memory cards for your camera, do it "now" because a 30% price rise is coming due to demand from AI. This will potentially impact smart phones, laptops, maybe even some digital cameras where RAM isn't part of the SoC.

Is Canon Finally About to Do Some New Super Telephotos?

This patent application (2025-159215) is a divisional patent application from a prior parent patent application, but this indicates that Canon is still legging it out and researching this. I find this interesting because it shows that Canon is thinking of novel ways to reduce costs or production time for some of the big white lenses. […]

Drop-in filters for long lenses

I'd like a roughly 3-stop ND filter for my 400 DOii to allow slower shutter speeds for panning photos. It came with the gelatin filter holder. I've heard mixed views on gelatin filters affecting sharpness. Has anyone had success using gelatin filters on long lenses?
In theory it is possible to get a drop-in screw filter holder that uses 52mm filters (provided they're not too wide or deep), but these seem impossible to find.
An alternative would be to get a drop-in filter EF-RF adapter. The genuine Canon one is quite expensive and for the relatively limited use it would get, I'm not keen to spend so much. There are 3rd party drop-in filter adapters, e.g. Meike and JJC. I have a set of Meike RF extension tubes, but the fit isn't great, even between two of their tubes - I wouldn't be happy to mount a heavy tele lens on it. I have a JJC normal EF-RF adapter (that I hollowed out to fit an RF 1.4x to my 400 DO) and that was quite well constructed.
So while I'd prefer a drop-in screw filter holder, I am interested in the JJC drop-in filter adapter (https://www.jjc.cc/index/goods/detail.html?id=2512)
Your thoughts appreciated.
Thanks

Did Canon See the Writing on the Wall with the RF Mount?

We've long believed Canon has been holding back the RF mount for profit, but what if that isn't the only reason? Did Canon look at the trends out of China's optical companies and realize that their greatest threat wasn't Sony, Nikon, or Panasonic, but the likes of Laowa, Sirui, and other Chinese manufacturers that were […]
