17/167, if I am doing that right. Although to be fair, I may be counting some sold bodies as lenses, as I don't distinguish in my "sold" folder. Still it is pretty clear that for a long time, buying and selling gear was my main hobby, as much as taking pictures was.

[j0n4hpk]

I was 4/1, but the best course is to keep the best lenses that you can (specially A, F and FA for full-frame).

[35mmfilmfan]

Apart from stolen lenses (do those count ?) I've only ever passed on three lenses - one with a film body to a local charity shop, in gratitude for delivering furniture to my actual flat (up the stairs) instead of just to the front door, one where I had obtained the upgraded model, and one where some twonk had dismantled it and lost some of the bits from the aperture ring ! (Cost me nothing, got nothing for it).

I don't like having overlapping lenses, I like that each of my lens have their own "specialty". And I don't like owning more lenses than I can actively use and preferably I would like to be able to travel comfortable with all my lenses.
At the moment I have these:

DA 16-85mm + DA*16-50mm (broken)
A 28mm F2 (no justification for this, but it's so pretty and tiny that I want to keep it + one day I would like to try it on a K-1)
31mm ltd
50mm Makro Planar
D-FA 100mm WR

I have sold 10 lenses including some CZ's and ltd's.
So I am 5/10. Though only five of these have been purchase as new.

Cheers

100/0.
Slow buying since 2010 (last lens bought in 2013...).

My lens collection has slowly evolved over time. Some lenses were purchased at one time because they fit my budget as well as my quality and operational requirements. Other lenses were purchased for fun or for having had the experience of using them.

I don't think I'd be able to put a figure on it but the one which has survived all cleanups to date is the DA*50-135mm which goes back to my K100D-Super days. The Sigma 85mm/f1.4 (or "the Beast" as my family tends to call it) joined a few years ago and most probably will remain with me until it breaks or I break, whichever comes first. Number three of the lenses I consider to be irreplaceable is the Sigma 8-16mm.

The rest of my bag is rather fluid I'd say - I use a lens until I'm bored of it, come across something better or change my habits - then it goes to a new owner.

For example:

50/50 (or 1/1) means that for every lens that you buy you typically get rid of another one.
80/20 (or 4/1) means that every 4 lenses that you buy you use to sell one.
100/0 (or 1/0) means that lenses check in at home but never check out

Right now I´m 100/0 but if I keep my LBA I will have to start saying goodbye to some of them (not enough room).

I am in the last group.

The lens I use the least are " vintage " film hold overs:

Vivitar Series 1 3.5 200 mm prime af in lens 67 f (Cosina)

Vivitar Series 1 2.8-3.8 1:28 - 105 mm macro zoom mf 67 f (Cosina)

Vivitar Series 1 2.8-4.0 70 - 210 mm macro zoom [1:25] mf 62 f (ver. 3, Kosine)

and for the amount of $ they might bring if sold, I choose to hold onto them

[Simen1]

Without proper counting, I think I have bought about 40 lenses and have about 30 right now. So a 75% keeper rate so far. I should sell my ~10 least used lenses so I have about 20 lenses and a 50% keeper rate.

For cameras I think I have bought around 20 and have about 15 right now. 90% of my images are taken with one of them, but I have various reasons not to sell the rest. Like too low value, special features, defective but decorative and so on. My oldest camera is an Ensign Selfix 20 Model 2, made in 1933-36, still in good and working condition.

[climit]

At the moment I have about 30 and have sold about 10 lenses. I had about 40 lenses a couple of years ago.

[Timd]

I have a 60-250 that I might modify to fit both the K-1 and the K-5 but haven't had the fortitude to do it--something like being a virgin: don't know what I get if I indulge the impulse.

It's actually incredibly easy to modify it. You unscrew 5 screws, remove the baffle, then screw it back. It's worth the effort....

Lenses tend to find a long-term home with me. That is, they usually stay in my kit as long as I'm invested in a particular system, of which I can only justify running one at a time.

I select lenses carefully and purposefully, with a focus on slowly building a capable, versatile, yet somehow affordable generalist-photography kit. Given the care I take with the selecting, I've rarely had regrets about acquiring a lens. What has certainly changed over the years is the frequency of use my acquisitions (all new, up to now) are seeing, but this may be largely due to the advent of digital and the no longer present need to justify buying film and (once I'd made the switch from slide film) prints, as well as my rekindled interest in photography and greater happiness with the results.

Currently, the only lens I hardly ever use anymore is the 18-55mm WR kit lens that came with my first Pentax, a K-7. It's not a bad lens for what it is, and it has given me many keepers for the first couple of years, but simply doesn't stack up well against any of the more serious Pentax glass that I own. In fact, I chiefly keep the kit zoom, because it is my only WR lens and allows me to give my K-3 a gentle rinse when it is dust-elimination time (maybe once or twice a year).

[normhead]

I recently parted with 2 A 50 ƒ2 lenses I had no particular use for and a couple of 18-55s as well. That would make my lens ratio 22 purchased 4 sold.

[timw4mail]

Currently, I'm at no lenses being sold, but with several still on the way, I'm not sure how long that will last.

[chuck_c]

The first lens that I ever purchased was a Tamron F 28-70mm f3.5-4.5 that I acquired with my first Pentax camera, an ME Super, in March of 1985. I still have both of them and every lens and camera that I have purchased since. Except for a K10 and A 50 f2 that I gave to one of my granddaughters. So that puts me in the 100/0 category.

[TaoMaas]

I'm pretty much 100/0. I've sold or traded a few lenses over time, but I've hung onto the vast majority of them. I need to change that, though.
