50mm autofocus fail

321/365
321/365 by Tim Caynes

It has been a little while since I acquired my new Minolta 50mm lens for my Sony A300 and I’m steadfastly refusing to take any photos where the thing I was expecting to be in focus is in fact in focus. I’m am now quite adept at getting most of my nose quite sharp but since there is a significant surface area to work with there I’m not counting it as a result. The thing I’m really trying to grapple with is while I’m still locked in to my 365 project and consequently taking far too many photos of my own face every day just how do I get my new lens to focus on one of my eyes. Either one, I’m not bothered. Just focus, pin sharp, like I know you can. On that blue bit in the middle where I’m trying to look all angsty. Yes, there. No. That’s my nose again. Grrr.

I am probably making the proverbial rod for my own primordial back being firmly clamped at f1.7 until I get this right, but then, that’s not about focus is it, its just about depth of field. I could have a depth of field like f0.3 or something and still get one of my bloody (for they are, after about 10 hours of trying) eyes in focus notwithstanding the fact that at that aperture I’d probably get eyelash bokeh but that’s not the point. The point is, I haven’t mastered this lens yet. And I’m running out of time. Kind of. This year’s 365 project concludes neatly on December 31st, after which I shall probably treat myself to the flickr equivalent of a 3-week Norwegian cruise, that is to say, I might not post anything for a day or so. Without my 365 project, I’ll not nearly be so inclined to invest the hours it will apparently take to crack this self-portrait focus failure which would be troublesome as I rather like the lens. I guess I have 30 days to sort it out.
