What is the worst Pentax lens ever made?

My worst ever Pentax as the FAJ75-300mm. Blurry, messy, slow to focus, a disaster mechanically, crappy hood. I don't think I got many keepers with that one.

Here's why I love the DA*50-135mm so much. A bit of a typical Dutch autumn day with lots of intermittent sunshine between some totally overcast moments. I spotted these sheep while walking my Old English Sheepdog (what's in a name) this afternoon. The sheep didn't mind me but although we were at distance, the sight of my fluffy companion made them pay attention. This one caught my eye as he was looking at us so intensely from afar. Regretfully I still had the CPL on the lens from shooting blue skies just an hour before.

Even with CPL, focus lock was instant and with f5.6 the dof and bokeh turned out very pleasing. What jumps out at me every time I pick up this lens though is the almost 3D feel of the result. PEF converted with DarkTable and slightly cropped for composition in Gimp. (click for a larger version on my own photo gallery). This is why this lens has been a favorite ever since I purchased it for use on my K20D back in 2010.

Thanks to all who replied in this thread. I have received a great number of useful suggestions which I am pursuing and I'm sure my beloved 50-135 will not be without a hood much longer and I can go on enjoying it for 10 more years!

I don't really care about the UK as it's non-EU now and I'm in NL. Ecommerce packages into the EU have been subjected to new rules since July 1st and while most international webshops have already registered for VAT under the EU's IOSS scheme (like Aliexpress, Wish and many others) B&H and Adorama have not. This would make import extremely costly. The example of B&H would be $64 + ca. $20 (depending on shipping choice) + 6.5% duty +21% VAT + €15 import admin fee. Roughly that works out to €106 or $125 by the time it hits my mailbox. Other option may be letting B&H handle duty & taxes and turns out slightly cheaper at $104.

If I'd be left with no other option, I may still weigh the option but I've received some very helpful suggestions which I will pursue first. The point of this being that if the DA*50-135mm is still being sold in the EU (presumable imported by Ricoh Europe from Japan and distributed to official retailers and via their own webshop) there should not be a reason not to have the hood available for purchase as well locally. But that point has already been made so I won't belabor it further.

Thanks for all who have responded! And yes, if the SDM would have failed, the front element cracked, the mount torn out, focus motor failed, fungus etc. I would have taken my licks and moved on with a new one - would have probably bough the very same 50-135mm again, it's thàt good! But it is only the plastic lenshood, should be no reason to junk a lens in this day and age of environmental worries - little part breaks, throw the whole thing out?

Currently using the same solution Bertwert suggested with tiny slivers of black double-sided tape in the "canals" - work like a charm but bagging or storing the lens and changing filters becomes a bit cumbersome. It'll do for now though.


Yep, saw those as well but with the new eCommerce customs regulations in the EU they will run up import costs like crazy if packages get through at all (Customs regulations are part of my job so I know the burn...)


Not sure you read my OP - the lens is doing perfectly fine. Just trying to purchase a plastic accessory for it. To use your laptop example: the laptop battery is fine but the charge cord is broken - simple charge cord & power plug but cannot get it anywhere.


Yep, read my OP where it says: "I can get aftermarket 67mm thread hoods but they don't allow pola- or other filter use and almost none of them have the right depth and petal shape to prevent vignetting."?

One of your links doesn't have the right depth for a telezoom and the other won't allow filters. Bro, I research before posting and complaining and I read EVERYTHING!



I contacted 3 different national dealers as well as Pentax Ricoh's own customer service in Europe. What makes you think I didn't? I was expecting to tell me that they'll have one for me in x weeks if I just have some patience - not just say "NO" like they did.


Again, eCommerce shipping into the EU is a b!tch since July 1st and B&H does not have the required EU IOSS/VAT registration yet.

First of all: I'm a long-time user of Pentax DSLRs and even owned a K1000 35 years ago. I've gone through lots of bodies from the K110D through to my current KP and loved them all to bits. But now Ricoh Europe has let me down so badly that I am finally considering other options. My DA*50-135 has seen constant use for the last 10 years. Never a scratch as I use the hood - ALWAYS. So plastic hoods have bayonet ribs which wear down with use, no biggie you'd say "buy a new one". Well, it seems the only way to get a new hood for the 50-135 is to buy a new...lens!!!

The PH-RBK 67 is on order everywhere I looked, in the EU, UK, even in the bloody US! So I wrote to the Ricoh-EU official support website. This was the answer:
"Unfortunately we do not have a PH-RBK 67 on offer."

That's it, end of support. I'm dumbfounded. Anyone any ideas? Yes I can get aftermarket 67mm thread hoods but they don't allow pola- or other filter use and almost none of them have the right depth and petal shape to prevent vignetting.

That's just regular raw conversion. My cameras are always set to deliver extremely flat OOC jpegs in case I want to do a quick edit. The PEF file of course contains a full range of data and conversion with a decent tone curve, contrast and some extra vibrance and saturation it brings the output to a realistic version. FYI, it really was a very beautiful sunny day and the sky was as shockingly blue as you see in the converted raw. In my case, I tend to trust the outcome of my raw conversion more than my ooc jpeg delivered by the camera jpeg engine. In other words: I did not "change the gray-ish color of the sky to blue" at all - the flat jpeg profile made it grey'ish in-camera.

And as an amazing circle rendition with one of Darla's scripts:


PS: before I forget, the perspective correction module when used together with lens correction in Darktable is so incredibly powerful! I’ve been using F/OSS software for over 15 years and never before had such powerful tools at my disposal. Especially the shot inside the museum was shot at a downward angle with a Tamron 17-50mm/f2.8 lens at its widest resulting in horrendous vertical and horizontal perspective coupled with the inherent weaknesses and lens errors and distortion.

Have brand new K-70 - worth taking a loss 7 trading for a KP?
Posted By newmikey

This thread made me look up my order history and some prices. I purchased the K-5 IIs (new) on 11/2/2013 and paid €809. The K-70 was purchased on 4/21/2017 (again brandnew) at €649 and I could not let the KP go when it was on-sale at my favorite brick&mortar photo store on 12/23/2019 for €669 - a price I never saw since! I know I only used the K-70 for some 2.5 years before I moved on but that was more for the incredible value of the KP offer and the thinking my daughter who shoots an old K-3 might use my K-70.

The weird thing is that I seem to be paying less and less for more capable bodies. What will be next? The K-3 IV for only €500? Who knows? In the meantime, I've added the 55-300PLM to the package which was a real steal.

Here's my take on the K-70 versus KP - I own both. KP has the better IQ but only by a very small margin at higher ISO. KP is sturdier and can take a battery grip. KP has the extra dial which is absolutely genius. KP is said not to suffer from the solenoid issues prominent in K-30/K-50. K-70 is cheaper - a lot. I prefer the fully articulated LCD to the hinged one of the KP. Ergonomically, I prefer the deep grip of the K-70 to any of the 3 grips on the KP.

Other than that - both are extremely capable cameras and you simply cannot be disappointed by either.

what got you into your career?

Q1: none of the above - pure chance, I'd say
Q2: I cannot un-remember/un-think the past 37 years so I really have no idea

The long story is that I got out of my mandatory IDF service (I lived in Israel at the time) as a combat engineer with a prior botched university career in physics - not really good skills for civilian success TBH. I frequented a job office for discharged soldiers and this really old, almost-dead, guy (he must have been at least 50 then, I'm 63 now!!) would go through these index cards - one by one, and sloooooooowly. He'd read a card, look at me, shake his head. Rinse & repeat about 20 times and he'd send me home to try again in two weeks.

After many sessions over a 2-month period (with unemployment pay not really covering my basic needs) I asked him if I could take a look at those cards myself. He shook his head at this literally unheard-of proposal (who would need civil servants if everyone would read their own cards, right?) but still let me grab the box of cards, quite certain I would find nothing.

I lifted out one card and said "how about this?". He told me it was for the Customs authorities over at the Lebanese border. He also said I would have to control a gate where some trucks would be wanting to pass on a daily basis (mostly UNIFIL). He explained I would have to walk out, check the documents, verify an unbroken seal on the container, stamp the document, open the gate, let the truck through, close the gate. (horribly exciting, I know!)

I told him I thought I could do that but getting back and forth to the "office" which was 35 km away might be an issue. He told me a Customs authorities patrol car would pick me up in the morning at a major crossroads near my home and drop me off there again at the end of the day. Sweet! I took the job.

That was 37 years ago this year. In the meantime, I have grown from opening and closing gates on the Israeli border to being an EMEA/Global Customs and Trade Compliance director for respectively US, Japanese and UK multinational industrial giants operating out of Amsterdam as well as chairing international conferences on Customs cooperation and technology. On the side, I teach a bit on subjects such as free trade agreement rules of origin, harmonized commodity coding and WTO valuation processes.

Looking back, I can safely say I had no ***** idea what I was getting into but it was worth it. My partial physics education helps me out now and then, knowing how to lay mines or defuse bombs regretfully does not...

You lost me there. Using an APS-C zoom as a FF prime?

Wide FF zoom: HD D FA 15-30mm F2.8 (similar range to the 20-40), HD D FA 24-70mm F2.8 as well as various 3rd-party options
Wide FF prime: FA 31mm F1.8 Ltd.(same FOV as the 20-40mm at its widest) and countless 3rd-party options (both MF and AF)


You lost me again. Those baffles on APS-C lenses are not there for fun or looks alone. Removing or permanently altering them will alter or even diminish IQ when used on an APS-C body.

I'm truly sorry for bringing what seems to be the only dissenting voice to this thread. I wonder why anyone would go through the expense of buying a FF camera to then mate it with a lens guaranteed not to bring out the quality the camera body and sensor are capable of. I can understand the scientific satisfaction and DIY excitement to prove it can be done but why anyone would want to put up with the mechanical and optical limitations on a daily basis is beyond me.

Really similar to buying a top-of-the-line APS-C body and mating it with a less than mediocre superzoom lens. If one would have wanted a single lens superzoom camera, why buy a DSLR in the first place?

If you want top-level resolution and sharpness, why put an adapted APS-C lens on a FF body instead of actually getting an APS-C body or FF lens in the first place? I'm truly sorry if this sounds obtuse, snotty or just plain grumpy but I really, REALLY don't get it.
