Favorable Exponynt: Pentax currently has the smallest 50mm F1.4. Will this be the largest?

I consider myself a hardcore fan, rather than a fanboy (I know you meant nothing bad by that). As I like what other companies are doing, too, and I'm not blind to Pentax' shortcomings.

I find brand bashing annoying, regardless which brand is the target. Those are highly qualified people who are making our cameras&lenses, they deserve our respect.

If you're talking about my post, it was far from Pentax bashing. It's actually a joke.
Hint: this Pentax is targeting quality, not sheer size.

The FA* 200-600 was as large as it needed to. So is the D FA* 70-200 f/2.8 (one of the larger such lenses), and the D FA 150-450 (which I own). The DA 560mm is necessarily longer due to its non-telephoto design.
However, this D FA* 50mm f/1.4 probably is slightly smaller than the Sigma Art.
(and here you have it, a serious answer).

I've seen a picture on the other forum:

Of course, this might not be final.

Impossible. Pentax doesn't have the expertise to design truly huge lenses, like Leica (Summilux-SL 50mm f/1.4 ASPH).
I'm worried that this D FA* 50mm f/1.4 won't even surpass the Sigma 50mm f/1.4 Art... in size. After all, it has a measly 72mm filter thread (77 on the Art, 82mm on the Leica).

davids8560: These new lenses from Ricoh Pentax clearly rank among the most important new optics to come along in quite a long time. This should be more than obvious to any fair-minded aficionado, regardless of their preferred platform. It is easily discerned just from glancing at the specs. So never mind all the comments. The more pressing question is what it means to Ricoh Pentax movement and prominence in the market in the larger sense. Will ultra high-quality gear predominantly aimed at still photography be sufficient in a marketplace full of comparatively more popular products like drone-mounted consumer action cams and increasingly advanced hybrid mirrorless still-and-video cams?

DPPMetro, I have a hard time believing that someone who only has negative things to say about Pentax is actually a Pentax user.

Since the K-3 Ricoh Imaging is gradually improving their AF; by introducing their first AF system with advanced tracking functions (SAFOX 11), then by iteratively tweaking it and improving step by step (the KP is said to have " completely new, much-improved" AF algorithms). They also introduced faster AF in lenses (and the new PLM - for now only in a crop lens - is very fast).

So, claiming that Ricoh Imaging isn't improving Pentax' AF is a lie. Saying the K-1 can't focus is a lie. Saying the K-1's firmware is broken is a lie as well.

The comparison with Samsung is plain and simple FUD, as there's no resemblance with Ricoh Imaging and Pentax. By the way, Samsung did the NX1 - impressively fast for a mirrorless - just before they closed shop.

Actually you can get a wide angle right now, it just won't be a prime. No need to go Nikon.

John C Tharp: By the size, it looks like they could have just rehoused Sigma lenses in WR shells like they did Tamron's- and that wouldn't be a bad thing!

What, are you afraid that if Pentax would design those * lenses on their own, they'd surpass Nikon? :-p

You know nothing, pkcpga - Pentax' lens factory is in Vietnam/Hanoi.

And Ricoh Imaging is plenty capable of designing high-end lenses of their own - the recent D FA* 70-200 being an example.
Why don't you speculate that every single Canon lens could be a Tamron design, or a Sony design, or anything but a Canon?

Karroly: Why is the D FA* 50mm F1.4 much bigger than the SMC FA 50mm F1.4 ?
Built-in AF motor ?
Additional glass elements/groups to improve IQ ?
OIS ?

@Ergo, I disagree, we're not disagreeing :-)
Yes, they're not identical and I never claimed they were - the 1968 formula was updated few times, but it still follows the original arrangement. Same elements count, same types in the same order.
I don't think "originates" means "identical".

No, it cannot be a Tamron. There's no Tamron 50mm f/1.4 to rebadge in the first place.
Why are you obsessively against the idea of Pentax developing lenses on their own?

Of course (I said above it's a 7 elements/6 groups double-Gauss design).
It was a failed attempt at making a joke, sorry - the formula works 100% for one element lenses (not exclusively so, of course). Otherwise, they can find ways of adding bulk.

This kind of double-Gauss 7-6 arrangement AFAIK was introduced in 1968, with the second version of the Super Takumar 50mm f/1.4 (unless Wikipedia is wrong ;-) )

You're right in pointing out that it was updated; but it's still very similar to the 1968 original design.

JaredTarzan: Rebranded Sigmas?

The D FA*70-200 f/2.8 is definitely a Pentax lens. Your software was showing incorrect information.

This D FA* is not a Sigma lens, would people stop this nonsense?

It's on the roadmap, also there's an ultra wide-angle.

The D FA* 50mm f/1.4 is not a single element lens ;-)

The FA 50mm f/1.4's optics originates back to 1968. It was obviously not designed for "full frame" digital sensors of 36MP and beyond.

noirdesir: According to DPreview there is only one other FA* lens: 70-200 mm f/2.8.

One other D FA* lens, and that's correct (so far).
There were other FA* lenses in the past, as well as F* and A* lenses. All of them were retired quite a while ago.
