Tamron 15-30 2.8 and Tamron 28-75 2.8 sample images for MilkyWay


Recommended Posts

Hi

I wanted to show some images off the 2 new Tamron Lens I got when I recently changed to a full frame camera.

I researched for ages to find a fast wide angle lens. I found it pretty hard to find sample images of Astro shots for the lens I was interested in. Plenty of Landscape shots, but very few of stars.

I hope these images help others who may be considering  either of these lens.

Here's the unprocessed images straight off the camera with my 2 new Tamron Lens.   -( Canon 6D Full Frame )

 

1st image is Tamron 15-30 2.8 lens @15mm 20 sec exposure iso3200 ( I added +0.75 Exposure in Photoshop just to make it easier to see)

2nd image is a crop of the corner of the image. You can see a bit of star movement but very little coma considering the lens is wide open at 2.8.

 

3rd image is Tamron 15-30 2.8 lens @30mm 8 sec exposure iso3200  (+2 Exposure in Photoshop)

4th image is Tamron 28-75 2.8 lens @ 30mm 8 sec exposure iso3200 (+2 Exposure in Photoshop)

 

5th image is Crop of the Corner -Tamron 15-30 2.8 lens @30mm 8 sec exposure iso3200  (+2 Exposure in Photoshop)

6th image is Crop of the Corner -Tamron 28-75 2.8 lens @30mm 8 sec exposure iso3200  (+2 Exposure in Photoshop)

 

Coma is a bit more noticeable at 30mmFL. You can see the 28-75 has a little more coma than the 15-30 but both seem pretty good.

I'm really happy with both lens which are quite usable wide open at 2.8. That's pretty Bright for a Zoom Wide Angle, and along with the 6D's quite low noise, it opens up some quick and easy landscape milky way shots without my tracker. I generally take 4 shots and stack to get a little lower noise. So when I don't want to set up my Star Tracker Ive got a good option.

They look good. I have the 17-35mm Tamron f2.8-4.0 OSD. It's pretty good at 17mm but a fair bit of vignetting at f2.8. Tracking at f4 is fine. I tend to use a Nikon 20mm f1.8 now for MW shots, it's sharp as a tack at f4.0

Hi, 

Recently I bought an used Tamron 17-35mm f/2.8-4 Di OSD. I thought to use it occasionally for some sky events, but I see that the 15-30mm one gives quite nice stars with Canon 6D. 

Do you have unprocessed (unsharpen) pics taken with your 17mm?

This is all I could find. It was ISO 1600 full frame D610, untracked 20s so some trailing

Set to 20mm and f2.8, there is some star trails but the coma is much less than my Nikon 20mm f1.8G, which contrary to my earlier post has poorer coma performance at matching f ratio.

There's a fair bit of vignetting at f2.8
