Is a diopter recommended for a 56mm lens?
Because of the very simple optical design of the diopter (or, technically more correct: close-up lens), the image quality will suffer a lot, e.g. from heavy chromatic aberration. The results will be ...

Canon EF 50 mm 1.8 STM - is my lens normal?
My copy of Canon EF 50 mm 1.8 STM is pretty old. But I see the same marks inside. For me it seems like mechanical thing, intended to tighten the elements inside.

Canon 50mm f1.8 VS EF-M 15-45 mm
Using the-digital-picture.com's test data comparing the two lenses side by side with the EF-M 15-45 set to 45mm and wide open at f/6.3, and the EF 50mm f/1.8 STM (on crop) set to f/5.6, here's the ...

What does an 85mm prime offer that a 50mm does not?
As you already pointed out, there are basically three aspects that will differ with using the native focus length vs cropping in.
Amount of Bokeh
If you use a wider lens, the amount of bokeh will be ...

Are faster lenses inherently better than alternatives if shooting with same aperture?
The one absolute benefit of the fast lens (even if "cheap") over a slow one (even well built) is that even if you shoot at the same aperture, during the measure/focus phase the fast lens is ...

Are faster lenses inherently better than alternatives if shooting with same aperture?
Ultimately, the preference is up to the individual photographer. And the speed of the lens is only one consideration.
The prime lens, whether faster or not, is generally a simpler design, which ...

Canon 50mm f1.8 VS EF-M 15-45 mm
This is more of a theoretical question that likely needs to be tested.
But, in theory, a prime lens will always be sharper than a zoom lens.
In theory, a kit lens balances cost over performance, ...

Are faster lenses inherently better than alternatives if shooting with same aperture?
Is there anything that makes such a lens inherently better performing than the slower zoom lens in terms sharpness, transmittance and other parameters?
No. Sometimes the prime may be better at a ...
