Tamron 17-50mm f2.8

Impressed with the PhotoZone test results ot the Tamron 17-50mm, I bought one on the forum marketplace and took it to one of my favorite spots, Short Sands Beach at Oswald West State Park between Cannon Beach and Tillamoook, Oregon. I am wondering in this zoom can replace my primes for landscape imaging. There was no time for direct comparisons - the tide came in too quickly, so that will need to wait. I am quite happy with the results, which look very good at 2:1. The main drawbacks I have noticed are curvature of field at 17mm [giving soft corners in some images] and the lack of depth of field scales, although live-view makes this less important.

I noticed that in LR3 if you apply the lens profile, the curvature at 17mm will be corrected nicely.

Great photos! This is my next purchase sometime in September. From all I have read, putting price aside, it's an amazing lens and compares really well to lenses three times the price. Throw the low price back into the mixture and it can't be beat.

Did yours have any BF/FF problems?

Lens profile, which I did apply in LightRoom, corrected for linear distortion quite nicely. I was referring curvature of the field of focus, meaning that corners do not focus in the same plane as center. To correct this, programming would need to render out-of-focus image into focused image. I hear this is on the way, but it is not in LightRoom today.

Thanks. No autofocus problems with mine, but I use manual focus for most applications in this focal range. I do sometimes use autofocus with my Sigma 8-16mm because it is darn hard to see focus at such wide field and small aperture, even with live-view.

Beautiful beach! The colors, especially the light green moss, are amazing. Most of these images have the color de-saturated with a moderate increase in vibrance, so subtle color is enhanced without making saturated colors unnatural - especially since they look unnatural naturally. Does that make sense?

This was a super low tide, so much of the foreground in these images in usually underwater. There were sea stars and urchins all over the place. I used an A50/2.8 for those.

I think the field curvature gets better with smaller apertures. The 17-50 makes for a great travel lens, although for landscape I wish it was a little bit wider, 16 or 14 would be nice. I make up for it by stitching, which usually works except when there's a lot of activity in the scene (e.g. waves). One nice thing about landscapes with the zoom is if you use a Cokin set you can get NDs and grad NDs for a variety of focal lengths with only one adapter.

I carry a Sigma 8-16 as well. Very good IQ, but the 17-50 is better.
