Sigma 70-200mm Lens problem with KP / ideas?

Sandy Hancock · 01-01-2018, 02:26 AM

I understand your frustration, but remember that although Pentax goes to great lengths to ensure backward compatibility with its own lenses, the company is under no obligation whatsoever to maintain compatibility with third party lenses.

The onus is Sigma to support *their* customers to keep their lenses useful. Like they did with the mount modifications after the K-1 issue.

The sigma is working fine with my KP. In fact, I'm surprised with it's sharpness handheld. Still needs more testing. If it keeps working fine, the problem could be that some sigma copies have issues as mentioned by other member or it is your Pentax kp (less likely I think). It could also be that I was lucky.

Good news! Sigma can do a Firnware update on my lens, so off to the post office today!

What a deal! It is not every day that a manufacturer provides service to provide forward compatibility to a new camera model several years after a lens end-of-life (2011). Your 70-200/2.8 EX DG APO Macro HSM II is a fine tool and it is good indeed that it can be updated to work with your KP.

That's great to hear TXPentaxK50. Nothing worse than having trouble with an older lens on a new body.

I wonder why Sigma would eliminate such a popular zoom lens from its offerings? Seems like a 70-200 2.8 would be a staple in any sports photographer’s bag.

It appears that Sigma is slowly winding down its Pentax-capable offerings. Is that reality?

I do not think "slowly" is the term.
Sigma Pentax mount is "gone" for all new lenses.

I may be wrong as usual.

It appears that you are right. All of the online retailers have mostly Canikon fitment Sigma lenses for sale. this is excluding the Art Series of lenses. I suspect there may be new old stock floating around, but other than what you see at Adorama and BandH good luck finding it.
I may be wrong also but this is just what I observed while spending way too much time and money hunting for Pentax compatible lenses during December.

I would think this is not good for the future of Pentax. Besides Tamron, what other third parties are manufacturing lenses that will fit the Pentax?

I don't think it matters a lot since there are new full frame lenses coming as well as amazing lenses still in production like the FA 77 and all the DA Limited's for APSC. That and all of the legacy glass that works pretty well for a lot of folks here. Use a Limited and believe in Pentax! They are full of magic!

They didn't. Your lens was replaced by a newer model of a different design in 2011 (also available in K-mount).

Steve can you explain what the term "full frame" means? I see that term a lot. Sorry if that's a dumb question.

Gotcha. For some reason I didn't see that lens under their Pentax offerings.

In the context of lenses, it means a lens whose image circle (the focused circle of light projected from the rear of the lens) has sufficient diameter to cover the whole of the 24mm x 36mm image frame without significant vignette. In the context of cameras, it means a camera that supports the 24mm x 36mm image frame. Examples would include 35mm film cameras and the Pentax K-1.

Not any longers, they stopped making the OS version in Pentax mount some time ago.
