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.

Welcome to Friday! That means the week is over, which is probably a good thing. I had a really hard time picking an image for today, as it turns out. Not because I just wasn’t finding anything good to toss up here, but because I had no idea what kind of picture I should go with. I had my buddy Roy help me pick one, and the choices I gave him ranged from stuff like this, to flowers, to snowy mountains, to some east-coast fall-color stuff. But out of the eight choices I sent him, he picked this one. Sorry that it’s a bit, ahh, disgusting.
As you probably know, I spent a fair bit of time this summer running around after bugs. As it turns out, there really aren’t very many interesting ones here in Seattle. I mean, if you were to head out into the actual, you know, woods, you’d probably find a few, but if you’re just looking at what’s running around my neighborhood, there’s really not much. There are a couple different kinds of flies, and a couple different kinds of bees. And then there was predominantly one kind of spider, which you’re looking at right now. Almost all of them that I saw were probably around an inch across, so not really exceptionally large in any way (although not too small either, for sure), although I saw some slightly larger ones as the summer came to a close. As it happens, it can be pretty difficult to get a decent shot of these guys, because they tend to hang out right in the middle of their web. But, webs move. So, while I’m trying to focus on the spider, the web can move several inches in either direction with even the slightest breeze. And there are almost no times at which there is no movement. If you’re not using a flash, it’s not as big of a deal, because then you can just let the shutter rip (although since you’re not using a flash, you’re probably using a longer shutter speed, which can cause problems due to the movement itself.) But if you’re using a flash (particularly a really cheap one like I was, that takes forever to recharge), it can be a real pain in the butt.
But, it’s not impossible, and then you get stuff like this. I’m not saying stuff like this is particularly great, I’m just saying that this is the kind of stuff you get, you can be the judge for whether it’s worth it or not.
Anyway, have a great weekend!

Wait, what?? This blog is still getting posted to? Man, I thought it was dead there for awhile. But then, BAM, just like that, a new post.
That’s right, folks, I’m getting back on the horse! The horse meaning, of course, the habit of occasionally posting pictures, maybe a few times a week if you’re lucky. I spent some time out of town over the holidays and all that, but I’m back now. Perhaps eventually I’ll even toss up a couple photos from that trip. But, not today. I haven’t even downloaded them from the camera yet, honestly. Hopefully soon, we’ll see.
In the meantime, here’s another insect and a flower. It’s true, this one is very similar to a photo I posted a long time ago. But, while it was taken at the same location (the Rose Garden in Woodland Park), it was taken about a year later, using different equipment. So it’s totally fair game. Because, you know, it’s all a game, with rules and stuff. And I hate breaking the rules.
Have a great weekend everyone! I’ll try and put up at least two posts next week, but I totally want to ease everyone back into this, so I’ll definitely take it slow.
