I purchased Nikon D5600 which comes with VR Lens.
I am not understanding the difference between:
Which one is better ? I read somewhere Nikon never came with EOS or OIS. It always uses VR Lens.
Is Canon 1500D better than Nikon D5600 ?
EOS is significantly different from VR.
EOS is a brand for Canon cameras. They use the EF or EF-S mount.
VR, on the other hand, is Nikon's reference to its image stabilization technology, which Canon calls IS.
So, you should compare Canon IS to Nikon VR. I think you'll find it varies from lens to lens how good IS or VR is. The quality of IS / VR is measured by the number of stops, which can sometimes be marketing-driven and hence exaggerated.
For example, 3 stops allows you to shoot using 2^3 = 8 times slower shutter speed. An IS/VR lens typically buys you 3, 3.5, 4 or 5 extra stops. Do note IS / VR only stop camera movement, and don't stop subject movement.
Both Nikon and Canon have the stabilizer in the lens. Canon 1500D does not have a stabilizer, but the kit lens it comes with may have. Nikon D5600 does not have a stabilizer either. Thus, it's absurd to say either Canon 1500D or Nikon D5600 is better. Some other camera manufacturers put the stabilizer in the body, but that is not as good for long telephoto lenses, where it's beneficial to put the stabilizer in the lens.
Different names... In Canon lenses, the stabilization is called "IS". There are two main stabilization methods:
It is an arms race between all lens companies. One may have the edge for a while for a specific application, but sooner or later the competition catches up or even passes it. So the problem isn't that much between companies but between specific lenses, the more recent design being usually better.
