EDIT: For now I'm going with the FA* 85mm 1.4 Ltd thanks to pschlute!
Warning: Backgrouond rambling. I'll bold the important parts.
Hi all! I haven't been here in a hot minute, but I'm an ex-equine photographer now only shooting my own animals for fun (namely my 4-month-old puppy). In another life I muddled along with a Pentax K-r and Tamron 70-200mm f/2.8, often doing a lot of compensation work in post given that my gear isn't technically pro level. I stopped shooting for $—honestly stopped shooting almost completely, because burnout—a while back and have long since taken my website down (and am at work without access to the actual files), but I threw some examples off Facebook/my phone
here—please excuse the compression/horrible IQ, I know. I pretty much stopped paying attention to photography, what's available, gear, ANYTHING, until I got my dog.
Well, I'm sick of hauling the old 70-20mm around to shoot her; I'm a short lady with puny arms, the dog is a LOT closer to the ground than horses are (I had to lie flat on my stomach in gravel to get several of the ones in the example album), and there are no arena fences to rest the camera on anymore (tripods and monopods restrict my mobility too much and I hate them). The puppy wants to be close to me, and a stay from across the yard (for portraits with the 70-200) is a lot harder for her than a stay from a couple of meters away.
In view of this, and the fact that my K-r is slowing down after years of abuse, I decided to finally bite the bullet and get a smaller lens—and upgrade to a K-1 while I'm at it, since I'd really like full frame (I'm sure you all can spot a few places in my example album where it would have benefited me, sigh, but I'm not April Visel/Wojtek Kwiatkowski and never charged those prices, and my clients were always happy). I really like a lot of background separation/nice bokeh, so I thought a 85mm f/1.2 would probably be the best fit for my needs based on my experiences with my 50mm f/1.8 AF (which is an OK everyday lens, but it seriously struggles in low light and I wanted the extra aperture for that, too).
I google, I find seemingly the only 85 f1.2 compatible with the K-1 (the Mikaton Speedmaster), and I order it. All hunky dory.
And then I see on a spec list, AFTER ordering, that stupid me, being exclusively a zoom lens shooter in practice, didn't think to check the autofocus ability/lack thereof...and it's manual focus only. I know how to use manual focus; I have countless photos of beads, laptop keys, very still-sitting humans, landscapes, whatever I was shooting while playing around learning how to use a camera.
You cannot shoot animals in manual focus. Not really. You can shoot a dog in a reliable stay or a sleeping cat, I guess, but anything with movement is going to get ruined. Even "easy" shots like
this one, where she had walked up to that plant and stopped for 0.5 seconds to sniff it.
I'm familiar with a thin DOF; 200mm at f/2.8 has gotten me many a nose in focus with blurry eyes. I'm used to compensating. I don't think I can compensate in manual, because my reactions are NEVER going to be fast enough to keep up with a sudden 2" shift that will throw my subject's face completely out of focus. I'm now freaking out a little bit. I don't want to have to return the thing once it gets here, but I do not have money to blow on a lens I essentially cannot use.
Now, I did find a
SMC Pentax-F 1.7x AF Adapter. Does anyone know if this will work with the Mikaton Speedmaster 85mm f/1.2? (Edit: I see someone saying that it'll essentially turn it into a f/2.8 lens at best, which kind of defeats the purpose...)
Failing that,
do I have any fast prime K-mount (ideally no wider than 70mm)
options for shooting moving animals that DO have autofocus, so I can switch to something
that is more portraity than a 50mm but won't murder my damn arms like the 70-200 does? Please, esteemed colleagues, lend me your knowledge, for I am desperate.
Thank you so much in advance!!!
