I didn't say it had, I said the new 70-200 will have HD coatings.

Does the DA* 60-250 have Aerobright? I doubt it, you mean the DFA* 70-200 f2.8 has. 60-250 has SMC and SP

What is a * lens? Are the current criteria, and the current standards the same as when the DA* 60-250 was released?
IMO the 70-200 f/4 cannot be a star lens simply because it's not f/2.8.

"To be designated as a Star-series product, a lens must demonstrate extremely high resolving power and contrast — from the center of the image field to the edges, even at open aperture — and exceptional optical performance with minimal distortion and color bleeding. In addition, it must be a very bright lens with one of the largest open apertures in its class. It must provide extreme strength, superior dustproof and weather-resistant performance, and outstanding operability. Only when all these requirements are satisfied, it is named a Star-series lens because it incorporates the very best of our state-of-the-art technologies that optimize the photographer's creative freedom."

I'm pretty sure all the DA* lenses have Aerobright coating on the front element. The New DFA* lenses (and I presume the DA*11-18) have Aerobright II.

The DA* 11 -18 has SP on the front, and HD elsewhere:

Yeah... I don't know why they mix it up. I like HD, know it works well and have 2x HD lenses, I know SP is for the front for protection but Aerobright I and II sounds like toothpaste

The coatings on the DA* 60-250 f4 seem very good for SMC, it is very flare resistant, I know SMC improved over the years.

There are different glass types too which is a thread in itself.

Finding things is not easy. As far as I know 60-250 has aero bright 1.

A German dealer today strongly hinted at the new lens being 70-210mm F4.

I fixed it

Until Ricoh Imaging says otherwise, it is a 70-200 f/4. Your dealer probably just assumes it is the Tamron.

Actually I do not care at all about a 50-135/2.8 APSC equivalent lens, regardless of focal length or maker. So let's just wait and see.
Your scepticism is ok.

Not scepticism, if it was the Tamron it would have been on sale ages ago I.e. a rebadge.

You know it is a Pentax lens coming as you need to wait years for it nowadays.

beholder3 · 03-09-2019, 11:56 AM

I just believe that no focal length speculated implies it is not a Pentax design. Unless you belong to the tin foil fraction or haters.

Are Pentax engineers forbidden to create a 210mm lens?

yes it contradicts the roadmap. Why not lean back and wait and see.

mbukal · 03-09-2019, 01:32 PM

If the Pentax is made with the same optic as the old DA * "new" HD DFA 60-250 / 4 ED DC AW in FA35 / 2 style, to a change from old to new, the star would be lost
then there would be a tele zum in the input rank that satisfies each beginner and advanced amateur who would have K mount and no other mount in FF, for all parts there is DFA * 70-200 / 2.8, why complicate such simple things that are proven quality, simple and quality and cheap to is proven by FA35 / 2, "I see logic in every respect"!

Pentax has never been as others, this would confirm the quality tradition it is different from other

**Rondec** · 03-09-2019, 02:24 PM

I think the big calling card of the 70-200 f4 as compared to the 60-250 f4 is going to be a significantly faster focus motor, well, and the fact that it will be full frame ready without surgery.

If people have the DFA *70-200 f2.8 and are happy with it or the DA *60-250 and are happy with that, then they won't be buying this lens from Pentax.

mbukal · 03-09-2019, 02:29 PM

jep, but there are those who want as longer and wider and optical quality and priced cheaper telephoto zoom, with a substantial difference in price from the star of the lens, not classical 70-300 ...., not classic 70-200 ...., when began in FA35 / 2 style, can continue with this proven lens...!

Impressive photos, Andrea.

I have a question. As I'm understanding it, removing the baffle allows more of the image and a wider field of view through to the sensor. Doesn't this mean that there is a wider field of view hitting the FF sensor compared to the APS-C, hence making it effectively (roughly) a 40-165mm (35mm equivalent)?

It means that the lens functions as a 60-250 on full frame cameras with minimal vignetting. It doesn't change its performance on APS-C. If you are going to do conversions, you could say that it functions the same as a 90-375 f5.6 full frame lens would when mounted on a crop camera. But I'm not sure we want to go there.

The focal length doesn't really change when the lens is mounted on different cameras, the only question is whether a particular lens covers a full 35mm sensor or not. In this case, it requires baffle surgery to cover it.
