These shots make me really want a 17-50. And they make me want to visit Yellowstone. Someday for both.

In the meantime, here's one with the 28-75 at 43mm, f/2.8.

You know what, I wasn't positive there was a 3.5, but there are so many varieties of Tamron lenses out there, I figured there just might be one. I also shoot primes whenever possible, but I love the quality of the 28-75. I missed it a lot more than I thought I would while it was being repaired.

I can't help but wonder what happened to my lens that they replaced. Will they disassemble it for parts? I hope they don't just toss it in the trash - despite being decentered, it produced some really nice photos.

About a week before Sandy came through, I sent in my 28-75 for repair of its decentering issue, under a Mack Camera warranty. Both Mack and the Tamron location are in the area hit by the storm, so there was some delay, but apparently a replacement lens is on its way to me. Of course, I haven't seen it yet, but I'm pretty impressed with Mack based on this news. I don't think the experience could have been much better.



Matt, the photos look good, but I'm just curious - why were you using the 28-75 f/3.5 if you have the f/2.8?

Wows. Seriously - when do you get close enough to a bird like this to use a lens with a max FL of 35mm??

I saw a 24-135 go for $175 on the bay recently. I felt like I had won the lottery getting mine NIB for $200.

Here's one from the 28-75.

A few with the 24-135

I really love this lens. One thing that's odd: Ever since I had my little fall that impacted my K-5 and this lens (at the hood), I can't autofocus using live view with this lens. Normal PD AF is perfectly fine. Live view AF is fine with other lenses. I've noticed no decentering or other issues with photos taken with this lens since then.

Yeah, the composition, particularly on the first, is rather meh. I could do either a square crop or crop off the right and edit out the line on the left. The second one could do without the pole and line, and I could crop out the elbow on the left.

Using the 72B 90mm macro as a candid portrait lens. Both at f/2.8.

If anyone out there is looking for a copy of the SP 24-135, here's a rare one on Ebay. Though it isn't fast at f/3.5-5.6, it does a very good job wide open at all focal lengths, which can't be said of most zooms in this range.

The above shot with this lens is at f/8. Here's a wide-open shot at 80mm:

The close focus is pretty nice, too. This scorpion was about an inch long:

Mike, I wish I knew something about unsticking the aperture. Please post what you discover.

Here are a few with the 28-75.

I recently bid and won an Adaptall-2 90mm f/2.8 on a whim. I'm pretty sure it's optically the same as the first AF version of this lens. I thought I'd probably turn around and sell it. Now I'm not so sure. The sharpness is just incredible. I have some sharp lenses, but there's something intense about the sharpness of this one, starting at f/2.8. Not really a special photo, but here anyway:

Thanks - yes, it does do a great job for portraits. I find that f/2.8 is just large enough to get the type of depth of field I like in a portrait. Your shot looks like near sunset - I love the light. What gave the fill light? It looks reflected.

Thanks, Rick. Without zooming in, it's often difficult to tell the difference between shots taken with the 28-75 and a prime. It's got great color and contrast from f/2.8 on. The decentering is only noticeable in landscapes and flat-field photos, which are rare in practice. For portraits, it's almost never an issue.


Ain't that just the way it goes - get repairs for one problem, get it back with a new problem. I'll try to post some photos of the issue with my lens later.

Decentering is the result of an individual lens or lens group within a lens unit being out of place. It usually results in photographs with blurring, smearing, and/or doubling along one side. It's more commonly noticed in large-aperture lenses. Stopping down can usually mitigate or correct the problem. To get it fixed, however, the lens will need to be sent to the manufacturer. With my lens (the 28-75), it only affects the leftmost tenth of the image, and it's only noticeable wide open at the wide end of the focal range. Wide open, at 40mm, it's gone, and at 28mm, by f/5, it's much less noticeable.

With the 28-75 f/2.8, 50mm, f/2.8. I got this lens because I wanted a zoom with a large aperture to use primarily indoors. I bought it used and didn't realize that it has some decentering evident at the wide end along the left edge until after I left feedback. Still a nice lens that produces usable results wide open.
