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.
