ran exposure plot today

24% of all my shots this year are with my manual aperture primes (0 entered for Fstop)

of known focal lengths, 11% each at 28 and 200 (actually 400 with a 2x TC) and 9% at 85mm, no other single focal length above 5%.

As a result, considering zooms from 10-200mm and 2x TC to 400mm, plus primes at 24, 28, 35, 50, 85, 105, 135, 300, 400, 500

I use them all about uniformly.

My results surprised me a little, although I suppose not that much. My most used lens was the M135/3.5, and mostly it was used for concert shots. Next up caught me a bit off guard, though: the DA18-55II, which I used quite a bit despite not having it with me very often. When I used it, I used it a lot - in particular, on couple of road trips. Ditto on the next one down, the DA50-200. That's slightly inflated since of the the shots I attributed to it were actually taken by my M200/4 or Quantaray 70-300, but those are lenses I take with me much less often. The 50-200 was mostly used at 200mm, for wildlife.

I suspect the 18-55's numbers will be going way down now that I have the DA15, as mostly I was using the 18-55 because it was my only lens wider than 28mm. Almost a third of the shots I took with it were *at* 18mm, and the 18-28 range accounted for over half of its usage. The DA15 already accounted for more shots than I might have figured considering I've only had it a little over a month.

As near as I could figure it based on focal lengths alone and looking only at the "keepers" except for the last couple of months when I counted everything:

19%: M135/3.5
17%: DA18-55II
14%: DA50-200
13%: DA70
9%: M28/2.8
9%: M100/2.8
7%: DA40/2.8
4%: DA15
4%: Vivitar 500/8 mirror

The remaining 4% were taken by someo combination of the Quantaray (Tamron-made) 70-300, M200/4, A50/1.7, and a couple miscellaneous lenses borrowed from others briefly.

Next year I expect the DA15 and M28/2.8 will see their usage go way up as I stop using the 18-55 so much. The DA40 will probably benefit from this a bit too. I might expect to see the usage look something like:

20% 135
16% 28
16% 15
14% 70
14% 40
10% 50-200

with the rest of the lenses taking up the remaining 10%. Maybe the Vivitar 500/8 mirror will steal more shots from the 50-200; not sure how I feel abut that yet. The above list without either the 50-200 or 500/8 is my regular kit; one of those comes with me when specifically looking for wildlife.

Things are actually in flux for me: getting used to a new zoom (got a 28-105 2.8-4) means I have to knock around with it a lot to get familiar. I don't use zooms often, but when I do, I make a lot of exposures.

Before that, about 85+ percent FA 50/1.4,

Call it, 10 percent A 28/2. (I'd use this a fair bit more if it were AF and/or faster: I can be dissuaded at times if my eyesight isn't cooperating: I have plans to trade this in on a faster AF lens. I've discovered that MF is OK for me for longer focal lengths, and likely shorter ones, but here I struggle to nail focus cause of how I use this FL and the low magnification.)

The rest split between a 135 'tak bayonet,' the kit lens, and things below margin of error guessing.

My guess is that it'll end up about 20 percent zoom, 20 percent 28mm, and almost all of the rest 50mm. I'm kind of set in my ways. In film, I joke that if someone glued my 85mm onto the camera, I might not notice for a few weeks. On crop, and with the high-tech stock screen, a fast 28 can do the jobs of a 50 1.2 and a 35/2 for me. Digital is bound to supplant almost all of the jobs I would use my trusty 35-105 3.5 for in film, even as I continue to shoot film.

For the last year... my guess is


Helios 44M 50%

Cosina 55 1.2 18%

Tamron 28-75 10%

Tair 135 2.8 10%

Vvitar 28mm close focus 5%

remaining 40 lenses 7%


The cosina was aquired late in the year so I expect it to move up big time in 2110

"What is your lens use percentage?"

100%. I never take a photo without one.
Your such a smart ass, I bet you could sit on an ice cream and tell what flavor it was!

Marc,
I want to see the spreadsheet with the data behind these calculations.

Pentax 50/1.4 - 40%
Pentax 18-55 - 35%
Pentax 55-300 - 25%

An now looking at a Tamron or Sigma 17/18-50/2.8, so the Pentax 18-55 will be mothballed and the 50/1.4 will be used half as much.

Pentax 17-70 is my walk-around lens and it gets by far the most use.

Next would come my Pentax 55-300 and then my Pentax12-24.

My most used prime is my Pentax 35 f/2.

Is there a program that compiles these figures?

Yes

the one I use is ExposurePlot what it does is scan the exif data in a directory (including sub directories) for the data. The defaults are focal length, aperture shot, ISO and shutter speed.

It is a little difficult for me as I have a bunch of manual aperture primes, and also use the *istD sometimes, therefore I don't always know focal length, but can identify by no reported aperture that a certain percentage were shot with my primes.

I haven't run exposure plot either but mostly use manual primes, too, so here goes:

on K100D:
Pentax AF lenses:
Pentax 18-55 kit lens 2%
Pentax smc f 70-210 5% (the AF drove me mad so manual usage only)

manual primes:

30% Contax Carl Zeiss 1.4/50 *
10% Yashica ML 1.4/50
08% Leica Summicron 2/50 1st version
06% Mamiya Sekor SX 1.4/50 *
04% Revuenon (Cosina) 1.2/55
03% Contax Carl Zeiss Distagon 2.8/28 *
03% Carl Zeiss Jena MC Sonnar 3.5/135 *
03% Carl Zeiss Jena MC Flektogon 2.4/35 *

02% the rest:
300/5.6 Hama mirror lens
Carl Zeiss Jena MC Pancolar 1.8/80
... various tested and rejected...

non-Pentax:
Zenitar 16/2.8 fish on Nikon film cam
Sony Ericsson k800i cellphone cam *

The asterisks make the cut to the next round in 2010

What I did was first list all my shots from 2009 (by clicking "2009" in ACDSee, the program I use to organize my pictures), then went to Details view and clicked the Focal Length column to sort on that. I then simply went down the list selecting groups of images at a given focal length or in given focal length ranges, and looked at the status display to see how many I had selected. So my numbers for the 18-55, for instance, I found by adding up the numbers of images in the 18-27 range plus the 29-39 range plus the 4149 range plus the 51-55 range, on the assumtpion that the shots at 28, 40, and 50 were with another lens (the corresondping primes for 28 and 40; the 50's were actually mostly with the short end of the 50-200). That gave me raw counts, then I just divided by the total number of images o get percentages.

Heheh, Georg. I think we have similar taste in glass.

Sometimes I drool over the Zeiss 28/2 and that 50.

I new your list was rather long and specific to be a guess.
