Messin' with the Rokinon 85mm f/1.4

robtcorl · 12-13-2012, 09:30 AM - **2 Likes**

It came yesterday, and I can't put my K-01 down!
Had a bit of focus trouble at first, even with peaking, then remembered to hit the OK button to zoom in.
DOF this thin is new to me.

All shots at f/1.4, jpeg from the camera, no PP.

100 ISO

800 ISO

1600 ISO
The tins in the back are about 3 inches behind the salt shaker.

I have always found that photographing dogs with fast lenses is tough because the DOF is so thin, when you focus on eyes, the snout is out of focus :/

I too just got one of these lenses, receiving my Vivitar yesterday. I took it to the rock gym last night and got the following:

ISO 6400 1/40 f1.4

ISO6400 1/60 f2.0

ISO6400 1/60 f2.0

While not super hi rez, what's amazing about these shots is that they are all handheld. The first one was in quite a dim lighting environment. This lens paired with the wonderful low-light capabilities of the K-01 lets me do things I couldn't even do with a film camera. At $300 this lens is a great choice for this camera!

I'm thinking about getting one of these as well.

How does it do in the MACRO mode?

There is no macro mode, and the close focus is about 100cm (39 inches).
This lens comes with different names.
Reviews found here.

I'm very happy with mine!

As mentioned by robtcorl, this lens does not have a macro mode. Here are some purely technical shots:

This is at F1.4. It was just beyond minimum focus, at 107cm from the front of the lens. That's just about an 8 1/2 x 11 in view. Here's the Picasa link so you can zoom in some. As you can see it is quite sharp, this pic doesnt demonstrate the IQ, (the other posted photos do,) but you can get an idea of how close it can get, and that it is very sharp, even wide open.

I also tried a #1 Pentax extension tube:

This is handheld, F1.4, Picasa Link. This is the shortest extension tube.
This is a really nice lens.

Thanks guys.

I know the lens is not designed to be a Macro lens but I wondering how it performed with the K-01 auto Macro mode settings. I guess I should have asked how well it works on detailed/macro type close ups.

I have been eyeballing this lens since yesterday and it looks like a great affordable lens. Almost bought one today but missed a $50 off deal.

A fine combination you've scored yourself - good IQ with thin DoF is no longer so elusive economically.

Just got my Rokinon 85mm.

What can I say.. The first 3min, I'm am ultra impressed.
Now I did have high expectations, so maybe my impressions are swayed a little... But, seriously... Very impressive.

Congrats, have fun!
Makes a nice birding lens if you are fairly close, and crop.

Nice shots.. Not really into 'Birding'
Much rather 'People-ing'..

here's my poor attempt at one of the few birds we see in the city.
