Pentax DFA 645 2.8 90mm Macro

DandA · 04-04-2013, 06:57 AM

Ken,

First Congradulations on the purchase of your 645D and lenses. I've been following the other 645D thread but have been extremely busy to post much lately. I have many/most of the lenses you just aquired and great choices!

For portrait work, don't forget the Pentax FA 150 f2.8 645 lens. It's made for portraits. Small, unbeliveably light and a wonderful dawing wide open for portraits that need to be well rounded and foregiving yet when the lens is stopped down, has excellent sharpness. A best buy at prices it can be obtained for. Just out of curiosity, where are you loacted? It nice to know where various 645D hail from. Have fun!

Dave

Also the 150/3.5 A is great for portrait. I bought mine for 60$. If you like a lens that is a little bit softer, more pleasant for portraits, the 6x7 165/2.8 is really perfect, too.

Thx for the comments!

I actually have 3 6x7 lenses, the 165 2.8, the 55 and 90.

Can someone who has the 90mm macro lens measure it for me (millimetres preferred) with the hood detached and reversed on the lens ? I'm planning on getting the lens but I'm afraid it might be to tall to fit in my camera bag standing up. I know my 25mm DA is to tall by a tiny bit and I have to keep it attached to the camera in order to fit it in my backpack.

Would be really appreciate it.

the 90mm macro length with butt cap is about the length/height of a sharpee pen.. or about 13.7 centimeters..

To consider also is a diameter (of the hood) of 10cm...

It's a real brick...

Hey, if you can afford the 90mm Macro it must be possible to get in addition a new bag.

For that price, I was hoping that It was going to come with an assistant to carry it for me ;-)

Yes, but I can't buy an additional set of shoulders for a second bag and the one I currently have is actually a perfect fit for long hikes. Having to store this lens laying down would either kick out my 300mm from the bag or I would not have room for any other items that are essential for a long day trip or an overnight stay in the back country. Now if the lens came with a free sherpa that issue would no longer exist.

No worries, it seems like you are satisfied with the lens so far and I'm very tempted to pick one up soon. Have you tried shooting with it from a boat ? How does the stabilizer behave in that situation ?

Yes, I am very pleased with this lens, and no I didn't try to shoot from a boat. I am going seasick very easily and as long the stabilizer only works for the lens and not for my disequilibrium I am not willing to test it...

Here's an example of the nice and rounded bokeh of this lens

I was wondering if anyone else feels that the noise made during "shake reduction" is fairly loud? A buzzing of sorts. I ask because, for instance, canon IS glass is pretty quiet and my former "shake reduction" pentax K10D was very quiet as the sensor moved. But this medium format 90mm really buzzes quite a bit , very audible sound. If others have silent copies , I will of course send mine back.........

Here are two photos from my first shoot around the house. I like the macro abilities. And the view through the lens is so bright ! (i have been using P67 100macro f4 or P67 55-100mm f4.5) The second image posted here was shot by handholding another old Kodak objectif in front of the DFA 90mm.......

Ristretto · 04-18-2013, 12:44 AM

I find my copy of the 90mm Macro very quiet, nearly noiseless. But I think it’s a question of “where do you come from…”; the only lens with SR I owned was the Nikkor 2.8/105 Micro VRII and that lens was very noisy – like somebody was playing marbles inside the lens
