Hello avarenity, Welcome to the Forum!
Very nice work with the fifty, it's a great walk-around lens. I like the colors, composition and scenes you've captured.
You might want to check the white balance on # 3 (curios), it looks like it's too yellow. Might be tungsten light? Otherwise it's an interesting subject.
Thanks for posting!
Ron

I found one for a good price here on the forum and thought I;d give it a try. I have an old A 50 1.7 which is nice but so is autofocus!
I'm used to having more controls, but it seems like a nice enough lens. It seems like a fast AF lens will come in handy at some point.
I took mine on a little ski outing tonight with my K-3 and saw this coyote running along the edge of the road on the way there.



It's been cold here lately. Here's some frost on my bathroom window when it was -13 out (warming from -24 the day before).



Lastly, some shallow DOF in a low light situation at f/2

The one of Saint Joseph I took outside of my office as I was leaving for the day, and cropped out the bottom half of it in PP -- no other adjustments. The second one only got a minor white balance correction and a bit of NR.

Bonjour,

Great shots and thread! Looking forward to participating here soon ... I won the DA 50/1.8 back on the Monday post-a-thon contest. Waiting for Adam to ship it to me after he gets it from Pentax. It will be my only AF 50 ... and was about to pull the trigger for a FA 50/1.4 at my local B&M shop ... too bad for them! Salut, J

Ah, but you surely need the FA as well

Seriously, though, congratulations on the DA! It really is a great little lens - as thoroughly proven in this thread

Merci savoche ... will hold off on the FA 50/1.4 for now ... ... and still trying to save up for a Tamron 70-200/2.8, but will never get there with a bunch of "small" purchase left and right ... J

[mattb123]

Congratulations! It's a nice little lens.

Thanks mattb ... if it's on par with the "Plastic Fantastic", I will be quite a happy camper ... big fan of my DA 35/2.4. J

Hi. Can someone please clarify: is the DA 50 a 50 or a 75 on my k01 crop camera? I keep reading that it is 75 on apsc, but I thought the DA line was made for crop and thus performed at the focal length printed on the barrel.

[stillshot2]

The DA 50 on my aps-c sized K30 gives a field of view that a 75mm lens would on a 35mm film camera. I imagine it is the same for the K-01 which is also an aps-c K mount camera.

[mattb123]

It's still a 50, but the FOV (field of view) is the equivalent of a 75 on full frame.
The size of the sensor doesn't change what the lens is, just the field of view you get.

[kharry2012]

So which would have the wider fov- the fa 43 (a film lens) or the DA 50 (a digital crop sensor lens) on my k-01? I would think the 50. I would think the 50 would be 50 and the 43 would be 64.5. Am I wrong?

No, don't complicate things. The 43 is wider.

50mm is 50mm no matter what it was designed for. The "crop factor" business has nothing to do with the lens and everything to do with the camera (or rather, the sensor).

The right thing to do is to forget anything and everything to do with crop factors. They are only (remotely) useful when comparing different sensor sizes. And they are downright unhelpful when discussing lenses.

I think everyone is confused by this at one time or another, partly because there is a lot of misinformation published online about it. Unless you have a long history of film SLR shooting and still use film sometimes I suggest you follow the advice given by savoche.

To answer your question I just took off my shoes to use as a position marker and mounted a DA 40 on a K30 and then I mounted it on a K1000. I focused both cameras into the corner of the room so as to align the left and right edges of the view finder on a window casing and the edge of the picture frame. Though the view finder I could see more image to the left and right through the view finder of the K1000. That probably would not transfer to film because the image would get cropped off (vignetted).

Conversely, I mount a 50mm A lens to the same 2 cameras, stood in the same spot. When focused on the corner I could just barely see those edges, the casing and frame with the K1000 + 50mm and the same lens on the k30 from the same spot showed a much more narrow view. Each of those image could have been captured with either camera as nothing would be cut off (vignetted).
