I’m curious: on which camera did you learn photography, and your first “professional” camera.

I owned a Brownie (Holiday? Bullet?), but in my photojournalism class at The Ohio State University in the late 1960s/early 1970s Paul Peterson introduced us to basic shooting and film processing using a 4x5 Speed Graphic. We then quickly moved to the Nikkormat FTn.

My Air Force public affairs office ("information office" at that time) had a Canon TFb and a couple of lenses. So around 1974 I bought my own FTb ($170), a 50 mm f/1.4 lens ($130) and a Vivitar 70-210 zoom ($204).

Absolutely not, as a rule anyway. In some specific instances it may be true. The only significant difference is that "D" lenses have an aperture control ring, and "G" lenses are "gelded". meaning they do not have the aperture control ring. The G lenses are always the newer design.
D type lenses are almost all now discontinued and being older can be purchased used for less money than G lenses, hence the appeal. But buyers have to beware as MOST D lenses do not have an in lens auto focus motor (a few do), so those lenses will not auto focus on the entry level Nikon bodies such as the D40, D60, D3XXX and D5XXX models. Both types of lenses will AF with all other Nikon DSLR bodies.

In reference to actually answering your original question: "... looking at the nikon j5 and Ideas how it shoots..." - I own Nikon 1 J1 and J5 mirrorless cameras. The cameras get limited use - such as when I capture images ‘on-the-fly’ at family gatherings or when traveling. However, I never use them in my studio or for services provided to clients. I especially like these smaller designed Nikon mirrorless devices because they have the capability for - decent - image quality captures, and they are so light! I do prefer to shoot in RAW format with my FX and DX Nikon dSLRs. However, I discovered images have better noise reduction when captured in JPEG format on these small sensor mirrorless cameras. Have attached a few of Nikon 1 J1 and J5 images samples from my database.

I recently purchased a new 24 - 120mm Nikon lens to replace my 28 - 300 kit lens for my D 750. I offered it for sale here, with 4 folks expressing interest, no one followed through. B & H offered me $ 450, and I was ready to send it to them. On that very day, in this forum, someone suggested KEH. I went to their website, found my lens, using their grading system graded my lens as excellent, none higher, and the offer was from $450 to $467.

I had thought B&H paid for shipping, but reading the small print, they want me to pay to ship it to them. KEH included a shipping voucher from Fed Ex, so took the voucher and the lens to Fed Ex two weeks ago. Two days later received an email verifying receipt, and advising up to 10 days to evaluate the lens. In today's mail was a check from KEH for $ 467.

For what it's worth, that would be where I would sell any future camera products. Yes, you may get a little more on EBay, if you're willing to deal with all the crap that people will give you, arguing about condition, who pays for what. Not for me. Clean and simple and in my mind, extremely fair.
