Canon Mirrorless versus Canon DSLR

3 years 2 months ago #706655 by tony-n-okc
Which Canon Mirrorless body and lens(es) would make you want to switch from your Canon DSLR and favorite lens and why?  I wonder if switching to mirrorless and investing in several compatible lenses rather than staying put with my Canon DSLR (EOS 70D) and EF/EFS lenses
(10-22mm, 18-135mm, 50-255mm, 50mm, macro 100mm) is worth it.  I'm just an enthusiast looking for feedback from someone who has switched.

Not gonna happen.

While mirrorless cameras are smaller and lighter than dSLRs, that doesn't extend to their lenses, which are just as big and heavy as their dSLR counterparts. So the size and weight advantage quickly diminishes as your collection of lenses and accessories grows. Also, the shorter Flange Focal Distance of mirrorless cameras requires their lenses to bend light more in order to project an image over the entire image sensor, so those lenses are more prone to vignetting, chromatic aberration, distortion, and field curvature (soft corners). That is not to say that those flaws can't be overcome, but in order to overcome them, lenses must use more advanced and more expensive designs. Thus, most mirrorless camera manufacturers opt instead to process images in the camera to "compensate" for some of those image flaws. Unfortunately, that processing often simply replaces one image flaw with another, and worse, there is no compensation for the field curvature, and the compensation for distortion actually makes the corners softer. Further, mirrorless cameras are comparatively new, as are their lenses, whereas SLRs and their autofocus lenses have been around for decades, so a new dSLR can use many of the excellent lenses available on the used market at a greatly reduced price. And while dSLR lenses can be adapted to work with mirrorless cameras, use of adapters often introduces other problems in terms of both functionality and image quality.

The issue is really what your goals are.  You can make comparable images with either one.  I use mirrorless cameras because I'm old and no longer want to carry around all that big, heavy gear.  I'm an amateur now so it doesn't cost me money to miss a shot.  So it makes sense for me.  The DSLR's have more extensive systems so they are probably a better choice for most pros.  But there are pros using mirroless technology as well.  Personally I would never go back to a DSLR.

G'day fmw + my ol' mate TCav

ps- I don't know where the original text has gone to ???? or what it was all about, but ...
I feel that each of you is both right & wrong at the same time ...... howz that for having a bit each way !!

The Pentax dSLR I had years ago also used 2x Sigma APO-designated zooms - and as TCav says - those lenses were as large as regular lenses.  They were also less sharp than the Panasonic FZ-30 12x zoom Leica lens unit that the Pentax was supposedly replacing - before it and the Sigma lenses were themselves replaced!

The Panny G2 that I acquired a decade ago came with the 14-42 & the 45-200 pair of lenses - and they are beaut and small in physical size and each is very sharp.  No distortions have ever caught my eye insofar as implied above, nor to my knowledge is there over-cooked (my words) camera processing to bring the wide-angle part of the lens image into some sort of 'correction'.  However, I agree with TCav when it comes to the Panny 100-300 lens ... it is -h-u-g-e- when compared with the 45-200

Against these are the sizes of the lenses on the FZ-200 / FZ-300 ... in native format = 4,5mm to 108mm -- the field of view being equivalent in 35mm / Full Frame format to 25mm to 600mm.  Although it is 4,5mm at its shortest (widest), being focal length it means that it is from the rear nodal point, and I (and I doubt everyone except the Panny technicians) know the precise physical distance from the actual rear of the lens to the sensor ~ but again, I do not detect distortions or light falloff

To detect vignetting &/or light falloff, I grab a landscape image that includes a clear sky, cut it in half and flip each half so that the original outer edges are now touching in the centre.  Any falloff that previously was hidden to the eye now becomes very prominent - and the Panny lenses do not show any issues of this nature.  So my conclusion is simply that the short focal length / short physical distances between the rear of the lens and the sensor does not make much if any difference to the end result

Hope this helps

With 5 DSLRs and 16 lenses, I don't think a second going mirrorless.
TCav touches many good points right there.

As long as my body can take the bulk — weight and size — I'll just be
more than happy with these awesome tools. My sons? When they will
be at the helm, it will be their decision.

Light is free… capturing it is not!
