So far I have the D FA 15-30mm and Iím waiting for my D FA 100mm 2.8 Macro WR to arrive. Plus an old M 50mm 1.4.

I think I may get the D FA* 50mm 1.4 and the D FA 150-450mm 4.5-5.6.

Still thinking about the FA 77mm 1.8 and the 35mm 1.4 Art, though.

Nikon discontinued some of their most usable lenses for the F-system. The super zoom 28-300mm 3.5-5.6G VR, the 105mm 2.8G VR and the 80-400mm 4.5-5.6G VR, which I think means Pentax will soon be the only DSLR brand.

And itís phenomenal to see Pentax introducing 3 FA lenses in 2021 and the near feature.

Small cut out piece D FA 15-30mm 2.8

The lady that sold the lens said it was in a bag and somehow got the ding. Proís sometimes have their equipment in a rough state.

The vendor is good, disclosed the problem, also sold me some other stuff that was better than described.

The review of the lens on Pentax forums, says the lens exterior is plastic, perhaps is less resistant, particularly that small part. It would explain why Pentax didnít name it a star lens.

I contacted Ricoh in the US and the service in Canada, hopefully they respond.

Worse case scenario, will tape it. And check periodically.

If I get the number of the part, maybe could source the part from Japan. Just received the plastic protector for the triangle strap piece and the hotshoe protector that wasnít possible to find anywhere.

The lens had a good price, IMO. Would have preferred one in better condition, even if more expensive, but modern Pentax equipment is less common than Nikon, Canon or Sony that are plenty available, even locally in Canada. Maybe would have had to wait for a while.

I have yet to receive the lens, but I saw thereís a crack in the mentioned piece and Iím concerned that the WR may be compromised, either by the crack or, since it deformed slightly, perhaps the seals around may not close anymore.

I used a photo from PentaxReview of the review of this lens to showcase the piece.

But this is my actual lens:

Hi there,

I posted this question in the B&H forum, but maybe should have posted it here as fellow Pentaxian suggested.

I recently bought a Pentax D FA 15-30mm 2.8 lens, but it apparently has a small blemish in the area of the cut out:

https://www.pentaxforums.com/content/uploads/files/6459/1767/medium/K1__9036.jpg

where the Tamron version of this lens has a switch for image stabilization.

Was wondering if anyone knows whatís the part number of this small piece and if it can be changed by the user?

Thanks in advance for any information.

Triangle strap protector for a K-1

Hello,

I eventually found the serial number, it's 38600. I have one shipped from Japan with the hotshoe protector.

Btw, from what I saw, Nikon also sell the protectors, that are slightly smaller, for their cameras.

Unfortunately, Iím not a big fan of APS-C. The K-3 III is quite expensive and wonít be available used for a while, doesnít have GPS and Iím not sure if it has the same tilt-shift screen of the K-1 II.

Since the difference between 35mm and 50mm isnít big, I think that may go with the D FA 15-30mm 2.8, D FA* 50mm 1.4 and the D FA 150-450mm 4.5-5.6 setup.

Plus something in between 50 and 150mm, to have a complete setup. Could be the D FA 100mm 2.8 macro, the D FA* 70-200mm 2.8 or the Rokinon 135mm 2.0?

Though, will go gradually over a period of time, with perhaps the 15-30mm first.

I recently bought an used K-1, upgraded to K-1 II, and while waiting for my D-LI90E battery and USB charger to arrive from B&H Photo, I noticed one of the triangle lugs doesn't have it's plastic protector.

Was wondering what's the part number of this piece and if can be ordered from B&H.

Thanks.

Hi Eye.n.Eye,

Thanks for the tips.

Was wondering why the HD D FA* 50mm 1.4 isnít good for AP? Is the HD D FA* 70-200mm 2.8 or the SMC D FA 77mm 1.8 that was also looking better?

Will check out the Sigma 35mm 1.4 Art, that lens is highly regarded, not only for AP, but I think it needs some modifications to be used with a K-1? Btw, does water condensate on the lenses after some time by night?

It may take time till I get to do some AP. The K-1 II has yet to arrive, and the only K lens so far, is the SMC M 50mm 1.4 thatís on the MX.

I used to have the SMC Pentax-K 135mm 2.5 in late 70's and early 80's. I think it's an inexpensive lens this days. Do purple fringing and CA affect the results one gets?

Was thinking long time to get a ZF.2 APO Sonnar 2/135, that can be adapted with Leitax products. Though something like the Samyang/Rokinon 135mm 2.0 for PK seems a more reasonable route.

BTW, is the Pentax-D FA* 70-200mm 2.8 recommended for this application?

Hi there,

I took some pictures of the moon and was started to think how to get into planetary and astro photography.

Soon realised to do everything "right" may need, 3 telescopes, several type of video cameras, expertise in wide variety of applications, a hefty German Equatorial Mount, tripod, computers and a very large number of filters and accessories, for a 5 figures costs.

Before moving in that direction, was wondering if there's a way to try with something simpler first, and recently tried briefly a Pentax K-1, after which I understood many YouTube and Internet reviewers don't really know that much about anything.

So, besides being a solid camera, with functions like the astrotracer maybe the GEM wasn't necessary to start with. And perhaps an composed pixel shift photo could allow for deeper cropping, increasing the reach.

But was wondering what lenses could be good for AP. Was considering the Nikon 14-24mm 2.8G, but the Tamron 15-30mm 2.8 is generally higher rated, specifically for AP, and was wondering if the Pentax-D FA 15-30mm 2.8 is a good lens for AP?

Since the only very sharp normal lens that actually have is 1.8 (Sony Zeiss 55mm 1.8), was also thinking if the Pentax-D FA* 50mm 1.4 should be good for AP?

If the Sigma 35mm 1.4 Art a good option? Will it be good without WR?

Another lens that was considering is the D FA 150-450mm 4.5-5.6, although that one is quite expensive and a bit duplicated by my other photo systems. Too bad EF or F lenses can't be easily adapted to the K mount.

Pentax would be my AP and landscape system.

What should use between 50 and 150.

What lenses are good for going over 450mm without breaking the bank? Is something like the Pentax-K 1000mm f/8 with a 2X TC good for planetary photography, given that it doesn't have ED elements?

Thanks in advance for the information.
