From my understanding, the lens hood is the main difference between the 25mm DA and D FA...not sure if they are optically different or not. I guess the only way to know for sure is if you take a hack saw to the permanantly attached hood on the DA lens and then see if it still vignettes on a 645 film camera...anyone willing to give it a shot and let us know? :P

I'm not volunteering!

I remember a press release n the change to the hood, I think the optics are the same. Given the number of film 645s out there, extending the hood so that the lens cannot be used on them seems silly. Not to mention that maybe one day the 645D sensors will reach the size of the 645 film plain (I think it's currently a 1.3 "crop factor" from film to digital).

I purchased the D FA 25mm, because it was used, so "only" $4000 USD, plus I knew I wanted to use Grad ND's on it, so the shorter hood would make that easier to do without vignetting. Plus, who knows what sizes sensors future 645D's will have...15.5mm equiv. on MF would be pretty cool, though limited. I'm thinking I'd have to make another stop at Horseshoe Bend to utilize something that wide!

I can't see them making the sensor so big that it would affect the DA 25 Would be a great way to p155 off your highest spending customers. The price for the DA is no less than the DFA. I'm heading up to the lake district tomorrow. Will be taking my Pentax gear and my nikon gear with me. Hopefully I'll get the weather t really give the DA 25 a good workout.

Who knows, but maybe the rumored 28ish - 45ish zoom lens that is supposed to come out soon will cover full frame and be offered along with a larger sensor 645D II, offering about the same field of view. I'm guessing that lens would be in the $6K-$8K range, sort of like the Hassy 35-90mm, which I think comes in at about $7.5K new

Ryan Tischer · 01-07-2013, 10:35 AM

By soon I mean 2013 or later, as seen in their lens lineup...I'm thinking later based on how slow they've been to release new 645 lenses.

Geokaz · 01-07-2013, 02:42 PM

With the price of the new zoom potentially in th $000s i will make do with my 25mm, 35mm, 55mm & 75mm for the long term i think.

@Ryan, hi Ryan, or any other user of this 25mm 645D lens, i am currently looking for a unit, but have the concerns that most have, ie the Grad filter issue, shooting in Aus/NZ, doing landscapes the DR can be quite high at times, sometimes im fine ,but others got to get out the Lee filters on my 35mm, also use the Big stopper a bit, so after seeing Hark Lees, fairly impressive holder system, has anyone else copied this ? come up with there own ? bought a system off the shelf etc, of course bracketing etc can be done, but i prefer to use filters, as i have them already.

Also im reading that at best you would only get one filter in any holder due to Vignette etc, can any of you users verify any or all or none of this,
Cheers to all and happy snapping..

Incredible! I love it.

Did you use a star filter for the lights, or is that a natural artifact of stopping down the lens iris?

Pentax 645D, D FA 25mm, ISO 100, f/22, (4 image HDR)

Captured along Lake Superior this morning

itshimitis · 01-08-2013, 01:27 PM

Some more with my DA 25.....

Am on my way to the Lake District, some from London where I popped in on a friend of mine:

Pentax 645D DA 25mm f/8 1/8 ISO 800 (handheld)

converted in Silver efex pro 2

Some taken with camera on a tripod. I have fused 7 shots in Photomatix on this first one - it does look very busy, but then at 4.45pm The City is very busy

f/13 ISO 100

The second one I fused 3 shots from that set
