Today, after long reading this thread and more and more
I made my decision after trying out the two finalists, Nikon Z50 and Sony A6400.
I had the blessing for extra $ from my husband - end of the month is my birthday..and Xtmas is not too far away.
Sony A6400 is the one I got. Smoother to play with it, more lenses to choose from, included from Sigma in case.
It came with 50mm and 210 mm lenses. I'm thinking to get -further down the road- a pancake lens.
Thanks for all your precious comments!
Something about this was niggling at me, and I finally got around to taking a look and clarifying something for myself. Ok, I think I've got this figured out.
Yet another piece of info as we induct our new mirrorless ILC user into this new world..... When using interchangeable lenses, one always refers to them as "primes" or "zooms." When talking about a prime lens, for instance, one would say that he or she was using the 35mm and then specify the specific f/number (f/2.8mm, f/1.8mm, f/1.4mm, whatever). When talking about zoom lenses one usually refers to the range that the zoom lens covers: i.e.: 12-24mm, 200-600mm, 100-400mm, etc. , as zooms can be either variable apertures or fixed apertures. So one would say, "I'm using my 70-200mm lens today to shoot when we're at the zoo." The range is often more important and meaningful in this situation.
When I go out on my deck to shoot the ducks, geese and my beloved Alfred, I've always got a zoom lens on the camera, and if asked, I usually will specify the range of that particular lens. When I'm shooting indoors and doing a tabletop scene or a macro shoot, I'm going to be using a prime lens, and so I would specify that it's the 90mm Sony macro or the Voigtlander 110mm macro, whatever it is....This info, or at least some of it, also shows up, by the way, in the EXIF that we can now see in the Media section here on MR under our own or others' accounts, so that if I post a photo of a flower, a Hooded Merganser or Alfred, members here can check the media info for that image and in most cases learn just what I used to shoot that image. However, this doesn't always work, as it is dependent upon various factors, so not everyone's EXIF info as presented on MR will be available or complete.
So,getting back on track here, what caught my attention in the original mention of what had been newly purchased was the reference to a 210mm lens. Something was tickling at my brain and I wasn't sure that Sony has ever released a 210mm prime lens, so had a look via Google to find out.
I am thinking now, Katbel, that what you've got for starters, and it's a good kit, is the Sony 16-50mm zoom and the 55-210 zoom, both nice lenses, which will get you off to a good start within a fairly wide range spectrum. Your mention of wanting a pancake lens, then, means that maybe you also want to add an ultrawide lens to your gear at some point, right? Or a fast lens that is a pancake lens? Actually, I think that for a while you'll have plenty to keep you busy with your two new lenses and seeing what they will and won't do for you.
One major difference between primes and zooms aside from the obvious, of course, is that prime lenses are often faster. This is where you'll find the f/1.2, f/1.4, f/1.8, f/2.0 lenses....... Some, but not too many, zoom lenses do offer a fixed aperture of f/2.8 or f/4, but not a lot of them. Variable apertures within a zoom lens' range is more the name of the game and for the most part it really doesn't make a big difference as long as one is shooting under good lighting conditions anyway, and these days one can go to a higher ISO without running into too much of a problem with noise, too.
It takes a while to figure all these things out, and eventually many photographers find that they seem to prefer primes to zooms or vice-versa, and they develop their lens "family" accordingly. Most people have a mixture of both but still tend to reach for one type of lens over another, depending upon what the shooting goal is, the subject, the potential lighting situation, etc.
I hope this helps you and hasn't confused you!
