Have:

Pentax 50mm F/2 (MF, 30 years old))

Used to have:
Canon 50mm F/1.4 USM
Sigma 30mm F/1.4 HSM DC
 
Prime

Tamron 60mm f/2 Macro.

I never really used it until the past few weeks, now I love it. I am going to switch to mostly primes now!!!
 
Currently my only prime is a Canon EF 15mm f/2.8 fisheye. Love it, although it's used infrequently.

I'm looking to get an EF 85mm f/1.8 one of these days

All others are zoom
 
I've owned two zoom lenses, and sold both...

Rangefinder lenses --15mm f/4.5, 21mm f/3.4, 35mm f/1.4, 50mm f/2, 90mm f/4, 90mm f/2

SLR lenses -- 28mm f/3.5, 31mm f/1.8, 35mm f/2, 43mm f/1.9, 50mm f/1.4, 77mm f/1.8, 85mm f/1.8, 100mm f/4 (Macro), 135mm f/2.5, 200mm f/4, 300mm f/4

Medium format (6x6) -- 50mm f/4, 80mm f/2.8, 150mm f/4

If you're looking to start a challenge with a specific focal length, you're going to have to deal with with different formats (4/3rds, APS-C, Full Frame, Medium Format, etc). It might be better to restrict it to a field of view (Ultra Wide, Wide, Normal, Short Tele, Tele, Extreme Tele -- however you want to break it up) -- a 50mm on 6x6 is a wide, a 50mm on 35mm-FF is normal, and on APS-C it's getting towards the short-tele range, and on 4/3rds it's a tele.

That said, a prime lens challenge could be fun -- I hope to find the time to participate.
 
Canon
24/2.8
50/1.4 - my favourite
135/2
200/2.8

Instead of a "shoot with xx mm prime lens" challenge, how about a few challenges like "superwide (<24mm)," "wide (24-35)," "normal (35-60)," "short telephoto (85-135ish?)," and "telephoto" challenges? Variety for everyone.

That might be too obvious and maybe it's been done before already. I've only been looking at this forum for a month or two.

Anyway - just ideas.

Jonathan.
 
I'd recommend that suggestions on variances of the fortnightly challenge be posted in that thread. I think (correct me if I am wrong) this was just a poll to follow up on one of those recommends.
 
Only have one, so far... 50mm 1.8 II

I am however shopping for another prime, but not sure if i want something wide like a 20mm, or something for macro type stuff like the 100mm 2.8 :)
 
30 mm f/1.4 Sigma
50 mm f/1.8 Nikkor

The Sigma is my most-used lens at the moment. I've really gotten to appreciate the way you work with primes. I think my next lens will be a wider prime, perhaps a 17 mm Tokina or a ~20 mm prime.

Canon 50mm 1.8 II
Sigma 30mm 1.4 EX DC

These are the only 2 lenses I own besides kit lens. The 30mm stays on 99% of the time, and the 50mm is attached to extension tubes for when I feel the need (rarely).

That Sigma 30 interests me. A lot of what I shoot with my 28-75 2.8 Tamron seems to be at 28mm. Sigma has a track record for iffy quality control. How sharp are the units you have?

All vintage Minolta AF, used on a Sony Alpha:

28mm f2.8 (xx)
50mm f1.7
135mm f2.8

I am getting into the 28 after using the 50 almost exclusively for the last 5 months. The 135 is nice but just don't have the need for that long most of the time (and when I do, the 70-210 f4 provides more versatility). Would like a 100mm macro and the 85mm f1.4, but don't really see either happening too soon, or ever for the 85 because I only want it for the collection and don't really know what I would do with it.

But the 28mm is my current go to. It is near normal but still fairly wide (as far as cheap primes go) on an APS-C. Really close focusing and fast AF, plus I only paid $28 for it.
 
15mm f2.8 fish (sigma, nikon fit, AF)
20mm f2.8 afd nikkor
28mm f2 mf nikkor
35mm f1.4 mf nikkor
50mm f1.4 afd nikkor
85mm f1.4 afd nikkor
180mm f2.8 afd nikkor
180mm f3.5 mf macro sigma

All used on a regular basis apart from the macro. I don't have a single zoom (have in the past but sold them all years ago)

Nice bag of glass, my friend. Do you shoot a day with one lens or swap between the ones that are close in FL like the 28 and 35mm?

Canon 28/1.8 , 35/2 , 50 1.4 , 85/1.8 , 100/2.8 macro , 300/4 , Don't use the first and last too much , the 50 and 85 are mostly used for portrait stuff with the family, 35 seems to always end up in my travel bag as a museum lens.
 
My lens I use 95% of the time is my Canon 25mm 1.8 I got for some ridiculously cheap price (and it is ridiculously cheaply made, worst auto focus ever) but its so fast!

One day I will get an L.
