  • Unless I'm missing something, AF 3 Preview AF doesn't do the trick. Focus locks immediately after shutter button is pressed. Continuous focus during 10 sec self-timer would be nice.
  • I've been using Canon GP-E2 receiver for 10+ years with my 5Dm3, R and R6m2. Works like a charm. Just two downsides: requires standard AA battery and takes up hot shoe.
  • Created discussion thread New RF 135 mm F1.8 handheld 1 sec
    New RF 135 mm is an amazing lens. I had an opportunity to play with it for a week. This pic was taken in dim parking garage, ISO 100, F4, 1 sec *handheld* (notice lights from bypassing car) with ...
  • Replied in Fantastic!
    Someday I'll own this lens! Now I only have old EF-version, but I love it.
  • Has served me 10 years with 5Dm3 and seems to work fine with my new R6m2.
  • Maybe also 70-200 F2.8 II. Built like a tank. Has served more than well for 10+ years already.

    Ok, now I see what you mean: Big O notation. It's true that many algorithms (e.g. sorting) need n log (n) time when n increases. But still I wonder, does this also hold for image processing? All ...
  • Ok, you're right - if images are from different cameras, they might have extra information (like DLO) that takes more time to process. It would be better to say "twice the information, twice the ...
  • If the workload (i.e. number of bytes) doubles, so does the processing time -- at least in optimum conditions (= enough RAM). You can't do better than that. You can do worse, however, if storage ...
  • It's quite simple, really: twice the data, twice the time - *IF* you have enough RAM. I guess with 45 Mpix you should have at least 32 GB. With 16 or 8 GB operating system needs to swap data in ...
  • I'd like to prepare for the future and shoot high dynamic range photos in RAW or HEIF for archiving purposes. However, workflow to convert RAW/HEIF images to standard JPEGs for viewing sounds too ...
  • Interesting. I have DNG Converter installed, but Adobe folder only has three sub-folders: Adobe (again!), Adobe DNG Converter and Adobe Lightroom. Adobe is almost empty, except AdobePatchFiles. Und ...
  • I'm not blaming anyone, this lens is great for its size, price and versatility. You just have to understand that software is the magic behind all this and if you buy it, you finally have to kiss ...
  • This needs more than just normal "software correction", esp. in the wide end (24 mm). If you still use LR 6.14 (last non-subscription version) I guess you're out of luck to get this corrected. Cano ...
