  • Replied in Use Flash
    Or two flashes, or three... Cut your exposure way back on that sunset, create a silhouette where you want and use the strobe to light the objects you want. You probably don't want all that ...
  • If you want to use a copy stand to photograph documents, artwork, a circuit board, food... a long focal length is a royal pain... you might need to put your camera four to six feet above the subject.
  • There’s much more to it than simply twisting the dials.  Yes, in general, wildlife photography requires long focal length (“zoom way in”) and high shutter speeds. How fast a shutter depends on ...
  • It doesn’t matter if mirrorless vs DSLR sales are 40-60, 50-50 or 60-40. Even if Mirrorless greatly outsell DSLR, there’s a huge body of photographers who haven’t bought new cameras. So the ...
  • First, the 55-250 is an outstanding value for getting into sports and wildlife. The next step up gets very expensive. Among the sub-$700+ lenses, it's the one to buy. The next notches up are the ...
  • Replied in It's no problem
    Before Coronavirus, I traveled worldwide many times a year and usually brought a full LowePro camera backpack with my 5D IV and an assortment of lenses. Along with that, I'd carry a smaller ...
  • Yes, if you put an f1.8 lens on the camera, you’ll have an f/1.8 maximum aperture.
  • Thank you! ISO is one of many examples of the benefit of empirical photography. Through theory (and way too much of it!) we learn that if I reduce my exposure and correspondingly increase my ISO to ...
  • I disagree. I think that the better path is to have a vague idea of all the variables, and a clear idea of how they make your image look, by using the equipment extensively and reviewing the results. ...
  • Option 1 by a mile.  The only strike against it is that lens is large.  It’s a lot of camera/lens to carry about,  but  you can pick up a 50mm for $100 when you want to carry something lighter. I ...
  • Replied in Canon VS Canon
    I think that website is rubbish and it can’t teach you anything.  It looks like it just pulls camera specs out of files and auto-generates the “reviews,” or else he writes the “reviews” based on ...
  • Replied in I wouldn’t
    I’ve never hear of Ted’s, and their website doesn’t even have an address.  They list the camera as the 250D instead of the SL3, so it’s probably a gray market import.  B&H and Adorama are ...
  • Replied in Simple Answer
    The camera shows you the actual f-stop. You should not change how you calculate exposure when the TC is attached. If you put a 1.4x TC on an f/2.8 lens, with and without that TC, you can shoot at, ...
  • People come here for help. Inserting confusion doesn’t help the people who want to take better photos. I like the original post because he’s asking why his empirical observations don’t match the ...
  • John, you’re just trying to take this person’s fairly simple question and twist it into something it isn’t. F-stop is the ratio of the lens focal length to the diameter of its entrance pupil.  A ...
  • Yes, but CMOS image sensor fabrication is different from the CMOS processes used in general-purpose semiconductors.

  • The image stabilizer can give you jittery images if you turn it on when the camera's on a tripod. Also, not sure why you'd use LiveView unless you also enable mirror lockup, which I think takes ...
  • That first shot is just stunning! A jaw-dropper. Great job!
  • Added 1 photo to their gallery

  • I don’t think there’s anything “Toyota” about the EOS camera system.  Canons are SO well built! I don’t really care what somebody else shoots with. They’re all capable. But Canon makes really good, ...
