K-1 3rd-party lens compatibility

Oh, and yes, it's a "8 255" lens. Exiftool (and Lightoom) correctly identifies it as "Sigma 70-200mm F2.8 EX DG Macro HSM II".

I'm trying to get in contact with Sigma on that.

Hi, according to your lens review it seems you have the lens with the oldest firmware as you mentioned problems with K5 live view focusing. I've updated lens FW five years ago as these HSM II lenses did nothing in live-viev on my K5. It only went forward, backward without lock. After firmware update it works as any other lens in live view.

This probably is the problem you have.. and now K-1 maybe uses the same shorter steps like LV on K5, to the lens has problems.

Sigma 70-200 EX DG HSM II is this one: https://www.pentaxforums.com/forums/attachments/36-sold-items/255150d14216609...m-k_3s2837.jpg

There are only three sigma 70-200 lenses (!)

Old body-driven 70-200/2.8 APO EX

Upgraded 70-200/2.8 EX APO DG HSM II

And then completely new stabilised 70-200/2.8 EX DG OS

I have the original versions, pre-DG, both the 70-200/2.8 and 100-300/4 and the matching EX 1.4x and EX 2x tele-converters. All work well on the K-1. The auto-focus speed on the 70-200 was very surprising, (very, very fast). Auto-focus speed on the 100-300 was "normal".

Ptitboul · 05-10-2016, 02:44 PM

From the info I collected in various places, I think that there are two versions of the body-driven lens: the "DG" which appeared in 2005, and an older version from 1999 which is not DG.
None of those is MACRO (they have minimal focus distance 1.8m) whereas the HSM version (appeared in 2008, also known as version II) is MACRO (minimal focus distance 1m).
The body-driven and the HSM variants have 18 elements in 15 groups, and the OS variant has 22 elements in 17 groups (and a minimal focus distance of 1.4m).

I've received information from Sigma's central service in Germany that they are still in the process of collecting all the information about the K-1 in order to issue a firmware update for the HSM II lens. The information was received via Sigma's service centre in Croatia.

Anyone want to buy a 70-200 HSM II?

There are many variants your last covers two

70-200/2.8 EX DG OS HSM (supposed to have mount issues on K-1)
70-200/2.8 APO EX DG OS (the last 70-200 in production not mentioned as having issues )

Giving

2 70-200/2.8 APO EX DG
3 70-200/2.8 APO EX DG Macro (released as Macro HSM in all mounts but PKA)
4 70-200/2.8 EX APO DG HSM II
5 70-200/2.8 EX DG OS HSM
6 70-200/2.8 APO EX DG OS

I may be wrong on the last two as it may be box Vs lens nomenclature

I am pretty sure that there has been only one OS version, produced from 2010 to 2014.

When was the Macro and not HSM version released?

Do you have more information on each of these lenses? For example, the OS and HSM II versions don't have an aperture ring, the non-macro versions have an aperture ring.

that's good to know....just in case I get a K-1

Correction: Actually have the oldest version, i.e., Sigma 70-200 F2.8 APO EX (not DG). As already mentioned - it works perfectly with K1 and suprisingly very fast AF speed given it is a screwdrive. NO scratching of K1 body - the mount flange outer diameter is 60.0mm. I heard the the HSM version was measured to 63.5mm - hence the problem with body scratching.

I have been testing my Pentax DA 1.4X AW rear converter http://https://www.pentaxforums.com/lensreviews/hd-pentax-da-14x-aw-rear-converter.html. All my tests have shown that it is full frame compatible with the K1 although the camera will set it to crop mode if set to auto crop so you will need to set crop mode to FF. These are the list of FF lenses that I have tested it with:

PRIMES:
Vivitar 13/2.8,
FA 20/2.8,
Tamron adaptall-2 28/2.5 PKA,
FA 31/1.8,
SMC DA 35/2.8 macro,
HD DA 40/2.8,
FA 43/1.9,
A50/1.2,
A50/2.0,
FA 50/1.4,
DFA 50/2.8 macro,
FA 77/1.8,
DFA 100/2.8 macro WR,
Vivitar series 1 A105/2.5 macro.

Zooms:
Sigma 70-200/2.8 APO EX,
F 35-70/3.5-4.5,
FA 24-90/3.5-4.5,
F 35-80/4-5.6,
Sigma 28-80/3.5-5.6,

NOTE: the SMC DA 35/2.8 macro is FF compatible (not sure on the edge focus) - just don't fully extend the built-in adjustable hood to avoid vignetting.

It's mechanical mistake in K-mount's dimensions of Sigma. It couldn't be fixed by firmware

Perhaps you would like to read back through this thread to see what it is about.

Before you start, you may be interested in knowing that there are at least two issues with Sigma lenses on the K-1. The photo you supplied relates to the mount clearance issue from today's Sigma press release, but that is not what this thread is about.
