150-450mm, there are AF button of four locations in the lens barrel, for example, can be carried out focus preset or Cancel AF, I seem to have become quite versatile lens. It is not a star lens, but because it is dust and water specifications, it is likely to be handled without problems in shooting in harsh environment. Price, it is going to be to the same extent as the first price of 80-400mm and Canon 100-400mm of Nikon.

I know everyone is excited about this, but what I'm scratching my head about is a DC motor? Really? Even in the 70-200 2.8? Tamron even makes an SDM 70-200mm lens with ring drive.


In 2015 Ricoh can't get ring drive ultra sonic motors out the door that work so they are still going with DC motors? Canon has had USM drive lenses since the 1990's.


Just sayin'


(PS, all my lenses for my K-3 and K5IIs are screw drive, so I guess a DC motor is an improvement...oops, I'm wrong! My Sigma FE and 8-16 are SDM. My bad.)

[VoiceOfReason]

DC is the same as on the 18-135, and it is dead quiet and fast.

[phoned]

Agree with the above. The DC on the 18-135mm is great. Also I think there is a huge stigma against all the SDM failures.

[sergysergy]

According to the translation the lens is a bit abnormal

Ricoh is between a rock and hard place with SDM and I'm sure you can work out why -
Can't "officially" say there was ever problem.
Can't "officially" say they have fixed it. ( Logic would say they have of course)
The fix - use a focus drive system in new lenses that is proven and has a more positive reaction in the market place.

That said - I personally would have no problems buying a new SDM lense today if it fitted my needs

You forgot the best 70-200mm of the bunch: Tamron 70-200mm VC USD $1300


And this is probably my number one reason why the FF Pentax could be good, maybe Tamron will release the 15-30, 24-70 and 70-200 USD lenses in a Pentax mount. I'm shooting the Tamron 70-200mm USD on a Nikon D810 and it's spectacular. DXO Mark got this one right, it's as good as they say.


But if Tamron does release it in Pentax mount it's going to make a DC motor FA* lens for $2300 look quite expensive.

and when,or if, something is announced we will get multiple threads complaining about what's wrong with whatever has been announced.

But,what means DC motor?
Nothing.
The motor in the kit lenses are small and only to use in light weight lens systems with short movement.
But there are lots of different types of DC motor.
The ring drive in the Pentax patent was NOT a ultrasonic like canons old type since the 90.
Old school,Nikon is using different types.
Here is a DC drive,looks more like the Pentax patent.

Direct Drive DC Torque Motors | Kollmorgen | Brush DC Electric Motors

Which is not a bad thing is it?
But one would have to compare features such as AW/WR, in-body compatible features and actual personal requirements before deciding if the comparison is balanced.

Of course. Why do you have a question about this? This is an internet forum, with the full self-flagellating Pentax mentality.

I see no problem here - it's just what is, eh? Dive in.

As far as I can see there is not a thread for this specific lens yet, so I made one. It's kind of confusing to discuss different lenses in the same thread.

This selectable quickshift mode and three stage focuslimiter sound like pretty nice features, once you learn to work with them. This lens will probably be pretty good for fast action.

Ha ha ha!
