So, here’s a ladybug. I used my Tamron 90mm macro lens that I picked up used at Glazer’s a year or two ago. The more I use it, the more I’m convinced that it doesn’t result in quite as nice of images as my Minolta-mount Kiron 105 that I got on Ebay. But, it’s a heck of a lot easier to use. That’s because it’s actually a modern, electronic lens that is designed for working with a Canon body, as opposed to an old, physically actuated lens that was designed for a mount that I’m not even sure they make anymore. The reason that makes a difference in usability primarily comes down to the aperture. With modern lenses, the aperture is held wide open as you’re focusing and composing, then it’s closed down to the desired size when you hit the shutter button. The minolta-mount lens has the same idea, but it’s done physically – meaning there’s a little spring-loaded rod in the mount that, when moved to the side, holds open the aperture. When you hit the shutter button on a camera that uses that mount, it then moves something out of the way that was previously holding that rod in place, thus the spring that I mentioned then closes down the aperture. But obviously, a modern Canon-mount camera doesn’t support that.
So, the upshot of all that is that when you’re using the Kiron lens, you have to close down the aperture before taking the shot. Which means that you’re restricting the amount of light that you have to focus with, sometimes severely so. And, to make matters worse, you’re enlarging your depth of field at the same time. So it becomes extremely difficult to tell if you’re focused on just the spot you want, particularly so when you’re taking macro shots, where being off by a millimeter or less can ruin the shot. Yeah, it’s hard. So, that’s what I mean when I say the Tamron is easier to use, because you can use the wide open aperture to focus, and it’ll automatically step down when you take the shot. But the images aren’t as nice. So it goes.

Just a quick post today to let you know that I haven’t forgotten about you all. I mean, I almost forgot about you all. But I kind of just barely remembered you when I was grabbing a cup of coffee. So in some respects I *did* forget about you all, just… not permanently. But don’t worry! I still love you all! As much as I ever loved you all. Which I guess means that I still … umm … don’t actively dislike you all. Umm… here’s a spider.

Let’s go with this one today. It’s (yet another) bee with (yet another) flower. But it’s Wednesday, and this makes me 3 for 3. I think these are lavender flowers or something? Hmm, whatever, not important. They’re nice enough to look at.

Don’t worry, I’ll inundate you guys soon with a bunch of Hawaii pictures, it’s definitely coming. In the meantime though, I’m just going to toss out a few more shots from the archive. Like this one. And no, this one isn’t from this year. I haven’t yet started going outside to take bug pictures this year, I think it’s still a bit too cold for them (the bugs, not the pictures), and besides, the flowers haven’t really started blooming yet. (Although some of the trees have…)
Obviously, I used a flash in this picture. The fact that it’s so obvious is actually one thing I don’t really like about it. The bee’s “skin” was just too reflective, so I got that crazy shine. I mean, in some ways it’s neat, because you can really see all the little grains of pollen stuck to his head, but using artificial light like that almost feels like cheating. Oh well, I’m sure I’ll get over it.
In other news, I believe the Skagit Valley Tulip Festival has started. Meaning, I’m pretty sure it officially goes from basically the beginning of to the end of April. I haven’t actually put any effort in to see if any tulips are actually blooming yet (although there are some daffodils blooming locally, so those are probably in full effect up there), but it’s probably time to start looking for a nice weekend day to head up there. If you’re a photographer, and you’re at least somewhat in the area (BC counts!) it’s totally worth checking out, you can have a lot of fun playing around with lots of different theme ideas. I’m tentatively planning on making it up there sooner or later, so maybe I’ll see you up there?
