DA10-17 @ 10mm MFD film

Whoa!

[ScooterMaxi Jim]

I acquired a Sigma 12-24 (refurbished - new) last year with the purpose only of testing it out to see how it performs, reselling it as Mint to someone who could use it on the FF (which isn't in my plans at this time). As many of you know, this lens comes in K-mount only as the original version from about a decade ago - the design that is more truly rectilinear.

Just curious if others are interested in this lens, or are people going to be settling for the less-wide options out there? I have the Samyang 14mm, so I expect to be satisfied with that if I do decide to go to FF in the future. However, it isn't strong in terms of distortion (need for true rectilinear isn't much of an issue for me). The 10-17 at 15mm strikes me as a very unappealing option - certainly not acceptable for any paid work. When I was mostly in Canon, I tried the much-sharper Tokina 12-24 on the 5D out at about 16mm - and it was brutal at every f-stop. I don't think any crop UWA zoom is going to look good on FF.

I don't know about using it for paid work, but it may still be fun to use. Are you sure it will really be that horrible?

I have the cheap little Olympus 9mm fisheye "body cap lens" for my Panasonic GX7, and although it's not going to win any awards for its technical merits, (although it's actually fairly sharp throughout most of the center area), it's still a lot of fun to use, and I've gotten a lot of great pictures with it.

In the unlikely event that I do get the Pentax full frame camera, I would only use the full frame lenses that I currently have:

Fisheye:
Tak 17/4

Wide:
Vivitar 19(auto ap), less likely Vivitar 21
Samyang 24/1.4(auto ap), Tak 24/3.5
Tak 28/3.5
FA 35/2(auto ap auto focus), less likely Tak 35/3.5, Tak 35/2

Normal:
FA 50/1.4(auto ap auto focus), less likely Tak 55/2
Canon (converted to K) 55/1.2

Telephoto:

Samyang 85/1.4(auto ap), Tak 85/1.8
Tak 105/2.8
Tak 135/2.5, less likely Tak 135/3.5
Tak 150/4
Tak 200/4, less likely Tak 200/5.6
Tak (1971) 300/4, less likely Tak (1962) 300/4
Tak 400/5.6
3M-5CA 500

Macro:
Tak (1966) 50/4 1:1 macro
Tak (1971) 50/4 macro
Tak 100/4 macro
Tak 100/4 Macro Bellows
Cosina 100/3.5 macro(auto ap, auto focus)
Vivitar 90-180

Unless you have personally tested it, that comment is completely absurd.
My DA10-17 is very sharp, it renders colours well, and its flare resistance is excellent. If your paid work requires a fisheye it is a perfectly viable option, especially if you already own it

[lesmore49]

My usable lenses on FF. My 10-17 FE, 50 F 1.4, 50 F 2.8 Macro, 150-500 Sigma.

Now for older manual lenses....28mm Takumar, 35-105 A , Macro Zoom, 50 F 4 Macro Takumar, 135 F 3.5 Takumar.

Also have modern Limiteds 21,40,70, 12-24, 16-45, 55-300. If I get a FF, would check and see how well these do.

Looks like you could just about get an APS-H frame out of that one.

Well, it just isn't good enough for serious work at the edges, especially when you do any stretching out of the FE compression. It really is a crop sensor lens, and fine for that use in typical fisheye fashion. As a substitute for lenses that you will use to shoot groups (weddings), landscape enlargements, or architecture, it doesn't strike me as designed for any of that. UWA is just so hard to design really well, and asking them to perform in ways they weren't designed for tends to expose weak points.

I have the cheap little Olympus 9mm fisheye "body cap lens" for my Panasonic GX7, and although it's not going to win any awards for its technical merits, (although it's actually fairly sharp throughout most of the center area), it's still a lot of fun to use, and I've gotten a lot of great pictures with it.

Funny thing, I bought one of those little lenses for by brother as a birthday present which he used on the GX7. Fun lens. Not sure it would compete with the 40xs, though (which is nearly a body cap lens).

You *can* get an APS-C frame. That's about it I reckon.

Samyang 14/2.8
FA 20-35/4
Zeiss Distagon 35/2
A50/1.2
Auto-takumar 55/2.2
FA77
DFA100 macro
Samyang 135/2
DFA 150-450 (but probably the DA 60-250 until I could afford this beast)

[mgvh]

I don't if I will (or can afford to) go full frame, but if I did, I have (with favs in bold):

• Rokinon 8mm FE (or the DA 10-17 in the 15-17mm range)
• Tamron 24-135 f3.5-5.6 (a very nice lens that is a bit better than the DA 18-135)
• Aetna Rokunar 28mm f2.8 M42 or Sigma Mini-Wide II 28mm f2.8
• Super Tak 35mm f3.5 or DA 35 f2.4
• F 35-70mm
• DA 40XS or Auto Chinon 45mm f2.8
• One of the K 50 f4 macro; M, A, or DA 50s; SuperTak 55 f1.8; Mamiya Sekor 55 f1.4
• Vivitar Series 1 70-210 f3.5 (v2) or Tokina SX-X 80-200mm f4.5-5.6
• Tamron SP AF 90mm f2.8 macro
• Takumar 135mm f2.5 Bayonet
• Super Tak 150mm f4
• TeleTak 200 f5.6 or M 200 f4
• Super Tak 300mm f4

I bought my first Pentax digital camera last Spring. Since then, I've bought, tried and sold dozens of different lenses.

I like manual focus lenses and place a high value on the quality of their bokeh. Below is what I currently have ready for the full frame:

Vivitar Series 1 13mm f/2.8 (same as Samyang Rokinon 14mm f/2.8)
Zeiss ZK 25mm f/2.8
Zeiss ZK 28mm f/2 (updated classic "Hollywood" design)
Pentax FA 31mm Limited
Pentax FA 43mm Limited
Zenitar M 50mm f/1.7
Zeiss ZK 50mm f/1.4
Cosina Revuenon 55mm f/1.2 MC
SMC Pentax-DA* 55mm F1.4 SDM
Helios 44-2 58mm f/2
Zeiss ZK 85mm f/1.4
SMC Pentax-D FA 100mm F2.8 Macro WR

You've got some fantastic glass to unleash on the FF, Fenwoodian!

[wizofoz]

I have had an eye to the unicorn 35mm Pentax for some time. Accordingly I have a reasonably typical set of FF lenses including the 3 amigo's, Fa50 1.4, Sigma 70-200, DFA100 macro and a load of older takumar and K and M lenses which will be fun to experiment with. Like others, the weakness in my line up is at the wide end. I doubt my DA 15mm is going to cut it, and it seems the 10-17 might be a little iffy over the range if I understand what Sandy has said above. I would also assume my 12-24 will be of limited use on the larger sensor body (please correct me if I'm wrong- I would be delighted.)

So I would assume my need would be for the 24-70 and/or something wider like the mooted xx-35. For still life/landscape I can use the taks, but for events or people AF is a must for me, I was not brought up trained on MF lenses.

Nice collection. You should try the ZK 35 some time.

What do you think of the 43 compared to the ZK 50 or DA*55? Also, how does the ZK 28 compare to the FA31, they're pretty close in specs, but perhaps not style.
