  • Not a problem.  The US has taken "modicum of skills" to new extremes and it's been so successful that even England and Australia are copying us and achieving greatness of the likes they've never ...

    ...a Z6 + 24-70 / 4S (12-35 / 2 mFT equivalent)? The combo is $2400 and 1.2 kg vs the Olympus EM1.3 + 12-40 / 2.8 which costs $2700 and weighs 1 kg. I know that while $300 is no big deal, 200g ...
  • I'm thinking that if the distortion characteristics of the lens are fully known, the IQ hit is negligible except for severe distortion (e.g. defishing a photo). Pedantic note:  lightening the photo ...
  • On another site, someone started a thread, "Why don't you wear a mask?" First response, "Because I live in New Zealand". Ouch! :-D
  • https://www.canonwatch.com/ (1) Canon EOS R5 body only option – $3,899 (2) Canon EOS R5 kit with RF 24-105mm f/4L IS USM lens – $4,999
  • Correction distortion likely results in negligible IQ loss. However, vignetting results in a more noisy photo towards the edges, since the greater the vignetting, the less the amount of light ...
  • Replied in Huh?
    All I'm saying is that 800mm f/11 1/2000 ISO 25600 on FF is no worse off than 400mm f/5.6 1/2000 ISO 6400 on mFT.  Clearly, one would prefer more optimal lighting and/or use a wider aperture to ...
  • The R6 doesn't look too bad price-wise.  I think it will launch at USD $2200 but "should" fall to USD $1899 within a year. I pair the 35-150 / 2.8-4 VC with the 16-35 / 4L IS.  My longest lens is ...

    By "sensor dirt", do you mean like which sensor is cheating on which sensor, and stuff like that? ;-)
  • Replied in Huh?
    So with mFT, you'd be at f/5.6 1/1000 ISO 500, which would result in the same DOF and the same total amount of light projected on the sensor (thus the same noise). So with mFT, you'd be at f/5.6 ...
  • Replied in F11 is F11
    OK. Likely so. No. No. Maybe a bit. A few points: (1) It's the amount of light making up the photo, not the ISO setting, that is the primary factor in the noisiness of the photo.
  • Sounds like you need a smartphone!  ;-)
  • I'm thinking the Sony bird photo would turn out more like these Canon FF bird photos.  Also depends on the photographer, of course.
  • Replied in Diffraction...
    ...goes like this: (1) Diffraction softening affects *all* systems equally at the same DOF. (2) Diffraction exists right from wide ...
  • As useless as f/5.6 is on mFT. Which doesn't mean jack, 'cause it's not the ISO setting that determines the noise in a photo. Assuming the focus area is the same proportion of the scene, then, once ...
  • Replied in Um, nope.
    It is equivalent in terms of focal length. It's pretty obvious that the quoted mantra has never been the case. However, it is far closer to being true than is comparing the same equivalent focal ...
  • ...and haven't read any of the thread.  But did you see DPR's review of the Tamron 28-200 / 2.8-5.6?  I was suitably impressed.  It doesn't have VC, though, so you need to rely on the camera's IBIS. ...
  • Replied in Great post!
    If your hand is steady enough, you can shoot for hours without any IBIS. My bad -- I meant 9 stops (I counted 1/50s as 1 stop instead of 0 stops using, as I said, the 1/FF equivalent FL rule). ...
  • Replied in Since you ask...
    ...until you take photos as good as these , you're not giving up a thing.  That said, an A73 + 85 / 1.8 likely costs less than what you used for your photos (G9 + 42.5 / 1.2), and is probably ...
