My base kit is my K-1 and DFA 28-105, Sigma 24 2.8 macro, DA*55 1.4.m, DA 55-300 PLM
or K-3, DA 16-85, DA DA 55-300 PLM, DA*55 1.4
Single k3 lens for walk around DA 18-135
Single K-1 lens for was around... DFA 28-105
Lenses and purposes.
DFA 100 macro - macro and walk around (mushrooms, flowers)
DA* 200 short telephoto, large birds and wildlife.
Tamron 300 2.8 - birds and wildlife
DA* 60-250, low light walk around.
DA*55- 1.4 - indoor events
SIgma 8-16 and DA 10-17 ultra wide and fisheye
Rokinon 14 2.8, astro photography.
FAJ 18-35.... real estate images.
So here's the thing, every one of those lenses was bought for a specific purpose, and without that lens for that reason, I can't do what that lens does. It's sad, but kit lenses don't do everything.
After an initial aquistion phase just trying to cover the basics, every lens was added for a specific reason, and increased the number and type of images I'm able to take. So the original concept is flawed. I do more, because I have more.
One might argue I have many lenses I don't use often. Those are to prevent malaise. When un-inspired, I'll think , OK, today lets see what I can get out of the FA 35-80. Sometimes I just need a change of pace.
The 35-80 is there as back up to my 28-105.
The 70 macro is a backup for my DFA 100
The DA *60-250 and DA*200 are there as the back up for my DA 55-300 PLM. In fact, I bought the DA*200 when my DA*60-250 was away being repaired. Thanks forum. I read over and over about lenses taking to long to be repaired. My DA*60-250 was repaired in 10 days, and was home before I'd taken 10 images with the DA*200. Forum complainers cost me $1000. Maybe why I take them so lightly.
In any case lenses increase functionality and lead to a more interesting experience. I pay more money to do more things. I keep my life interesting by engaging in different types of photography, and each category requires it's own equipment. On my daily dog walk, sometimes shots of the dogs, sometimes mushrooms, sometimes birds, sometimes images of friends who have come on hikes. Sometimes if I take my camera on the dog walk 4 times in week, I'll take the DA 18-135, or the DA 16-85, the DA*60-250, the DA*200, DFA 28-105, DA 55-300 PLM, FA 50 macro, the Sigma 70 macro, or the DFA 100 macro. And I look for a different type of image with each lens. It keeps things from getting stale.
If you buy a lens for a specific purpose, you expand your world photographically. You shoot more. I've had many, "I'm tired of the DA 18-135, I'll take the 100 macro as my sole lens" type of days.
I feel so happy for anyone who needs only kit lenses to do everything they want to do photographically. But if you're committed to having kit that allows you to particape in four kinds of photography , macro (flowers and insects), landscape (kit plus or primes), wildlife, birds, on a single walk, I have the ability to get 4 times as many images. The only thing wrong with the OPs comment is the lack of recognition as to why some of us have so many lenses. It's about capability. And saying one lens would do everything I want to do would be next to insane. So ya, there's a law of diminishing returns, although, my lenses lives will also be a lot longer because usage is spread around. But, if you don't buy the right lens for each specific area of photography, you can't even participate. Reduced lenses for many would mean reduced capability and less enjoyment.
Based on years of reading the forum, most people buy lenses for a specific capability, something they wish to investigate and participate in. Hinting they could get by with a kit lens is in most cases nonsense.
Cutting back below a certain level just means you're going to have occasions where you get fewer images because you don't have the right lens. IN that sense having a well selected stable of lens means you will be more efficient in capturing the images you find. So cost inefficiency is balanced against capture efficiency. Some of us have had the experience of missing out on a fantastic image because we didn't have the right lens and know the feeling of missing out, because we weren't prepared. Having the right lenses for what you want to do may be financially governed by the law of diminishing returns, but your photography is diminished by not having the lenses you need. So as in many things, if you just look at the money, you'll hurt your performance and your enjoyment. If you want to make the most of your opportunities, you need lenses for specific types of photography. And you need to own them. When that small moth is out there on the flower you need that macro lens now. Or the shot is gone.
So what do you want, money? Or a more satisfying photographic experience. If you just want money, don't buy a camera, unless you can make money with it. That would be the "Reductio ad absurdum". But it does illustrate the issue of trying to think about how much your lenses sit on shelf, as opposed to what each lens gives you that your other lenses do not. The original thought implies redundancy, and I have many lenses that overlap in that they do the same things most of the time, but each has function that belongs solely to that lens, that makes it worth keeping even if I only use it once a year. And that is my issue with kit lenses. They are for generalists, the are good for 50% of everything, but they don't allow specialization. But having only one kit as my only lens would cost me more than 50% of my photos.
So essentially, I'd reject this proposition in it's entirety. You need what you need. You spend the money to get the lenses that are for what you want to shoot. I don't see how missing half the available images I take would be in any way "efficient"
except, financially, and it is so hard seeing a great shot but don't have the right lens for you soon realize, photographically, overkill is better than not having the right gear for the images you want to take.
So my short response is "Do you want to be a banker, or a photographer?"
Or to be more precise do you want monetary efficiency ( a lot of use of a few lenses), or photographic efficiency (a higher capture rate of the photo ops you experience.) As in many things, you can't have both, and most of us go for a compromise, a lens for every type of image we take that we can afford without breaking the bank.
