So you're thinking about catching the mirrorless wave? Make sure you double-check all your reasons and assure you're not being fooled by the marketing hype.
(Myth List)
I know that list was tongue-in-cheek, but for the great unwashed who haven't seen the light yet:
1. When you remove the mirror, full-frame mirrorless bodies probably get thinner and might be a little lighter. But the BODY difference is likely insignificant in the general scheme of things.
2. Lenses for mirrorless bodies may be more or less expensive than dSLR lenses. They may be heavier or lighter. For SIGNIFICANT weight reduction, get an all-Micro 4/3 system.
3. If you buy a mirrorless camera, your existing dSLRs might GATHER dust. But they will still work.
4. Sony builds mirrorless cameras. So do Fujifilm, Olympus, Panasonic, Nikon, and Canon. Prices and features vary widely, because there are MANY models with MANY exclusive, desirable features.
5. SOME Sony (or Fujifilm, or Olympus, or Panasonic...) mirrorless cameras are better than SOME DSLRs, for SOME things. The reverse is also true. They may be more or less expensive, depending on the comparison.
6. Sony makes Nikon's high-end sensors under contract, to Nikon specifications. Nikon isn’t doomed… They're just late to the full frame mirrorless party.
7. Sony MILC* bodies have all the features and ergonomics that SOME professionals demand. (The same is true of all the other mirrorless brands.) *Mirrorless Interchangeable Lens Camera
8. Sony cameras are evolving products and have debatably useful documentation. Their menu structures are not for everyone. But documentation and menu structures elicit highly personal individual responses.
9. Each format — full frame, APS-C, and Micro 4/3 — has a niche to fill. Greatness may be defined as, “a high degree of suitability for the purpose at hand.” That purpose varies WILDLY from person to person.
10. SOME mirrorless cameras have short battery lives, compared to others. MOST mirrorless cameras have shorter battery lives than dSLRs. So? Life is full of little trade-offs. I'll take the EVF!
11. Mirrorless cameras may or may not have dual card slots. For some professionals, this is an important consideration. They're probably photojournalists or wedding photographers.
12. The EVF (Electronic View Finder) has evolved tremendously in the past decade. High end mirrorless camera EVFs are large, bright, and display minimal lag. SOME manufacturers get around the residual lag with some clever continuous buffering of a stream of images. When you press the shutter release, the camera saves the previously buffered frames. When you let up, you can scroll through a sequence of images and find the right one for your needs.
13. Sony RAW files have a lossy compressed setting that's NOT as bad as shooting JPEG. It has a purpose, just as JPEG processing at the camera has a purpose. With any camera, recording less than a full-sized, uncompressed/least compressed raw data file is a compromise of some sort. But it may be a necessity for your situation.
14. Image Stabilization in the camera (IBIS) is best at shorter focal lengths (below about 3X magnification). Image stabilization in lenses (ILIS/ IS / VR / VC…) works best at longer focal lengths providing more than about 3X magnification. God wasn’t involved, other than establishing the laws of physics.
15. The available range of mirrorless lenses varies WILDLY from brand to brand. Micro 4/3 has over 100 native lenses compatible with Olympus and Panasonic, and can adapt thousands more. Both Nikon and Canon have supplied adapters to mount their dSLR lenses on their mirrorless bodies. You can look up lens lists online (Wikipedia has several) to see if the lenses you need are available for the camera you want. MetaBones, Fotodiox, and several other companies make a wide range of adapters and SpeedBoosters or focal length reducers to adapt your existing lens mount(s) to your new mirrorless body. Feature support (AF, ILIS, metadata support, automatic diaphragm actuation...) varies from none to full. Performance (especially AF) depends on the exact combination of lens, adapter, and camera body.
16. Speculating whether Ansel Adams would have used a foreign-made mirrorless camera is just off-the-wall wEiRd. Does that even matter? We can't ask him.
17. You can get approximately the same depth of field from any SAME format camera using the SAME focal length at the SAME distance and aperture. When using APS-C, at an EQUIVALENT focal length as on full frame, from the SAME distance, you can open up one stop to maintain about the same DOF. When using Micro 4/3, at an EQUIVALENT focal length as on full frame, from the SAME distance, you can open up two stops to maintain about the same DOF. Fast prime lenses help. That’s why there are MetaBones SpeedBoosters and four f/0.95 Voigtlander primes for Micro 4/3.
18. If you go mirrorless, *in an ideal world,* you WOULD start over for your entire lens portfolio. However, nearly all Nikon and Canon glass can be adapted to Nikon and Canon mirrorless bodies. Canon glass can be adapted to Sony bodies and Micro 4/3 bodies, often with nearly full automation, but with some reduced AF performance. Nikon glass is the least adaptable to other brands of mirrorless cameras. Nikon glass adapts to Fujifilm with some limitations.
19. Legacy lenses are not optimized for mirrorless bodies. But they should perform as well as they did on *same sensor* dSLRs. If the mirrorless body has IBIS, they will perform even better at slower hand-held shutter speeds. While manual focus lenses do not suddenly gain autofocus, if the mirrorless body has manual focus peaking, manual focus will be easier and more precise, ESPECIALLY in low light. If the lens was a micro focus nightmare on your dSLR, it will focus perfectly on your mirrorless body, because there is no mirror to get out of alignment, and no separate focus sensor.
20. Mirrorless cameras do not necessarily take better or worse images than any level of DSLR. USER KNOWLEDGE, EXPERIENCE, TRAINING, SKILL, INSIGHT, FORESIGHT, POINT OF VIEW, AND PASSION mean one helluva lot more than the differences in cameras. Good gear makes good results easier. But on any given day, that stuff in all caps probably means more than a brand name, sensor format, or model.
