First Impressions :: Tamron SP 150-600mm Di VC USD LENS
I have had the pleasure of working with the new Tamron SP 150-600mm f/5.0-f/6.3 for the past 10 days and have now had enough experience to say this lens will become a permanent part of my landscape bag!
Initially I thought, “No way. There has to be a portion of the zoom range that just won’t be sharp enough for my standards!” Well guess what, I was wrong. As I have been telling my fellow pro colleagues, it is tack sharp from 150mm to 4500mm, then sharp all the way out to 600mm.
Tack sharp is a term pros use to describe an incredibly sharp lens. These are images sharp enough that just a bit of sharpening in the RAW converter would be all it takes. Sharp focus means the lens is still sharp, but could benefit from more sharpening in RAW.
This is not a blog focused on tests of stationary subjects and wall charts; rather, this is real world shooting and 40 years experience of looking through a bevy of camera and lens combinations. In other words, this is just my opinion.
Moreover, this is not a piece that compares and contrasts similar lenses from Nikon, Canon, and Sigma. Instead, I am just going to show and talk about a variety of subjects and lighting conditions and how I felt this lens held up to the challenge.
All images in this blog were captured with the Sony version of this lens on a Sony a7II camera. I also used a Sony A-Mount to E-Mount Adapter with a translucent mirror.
NOTE: I plan to write a separate review of the Sony A7II shortly. CLICK ON ANY IMAGE FOR A LARGER VIEW.
First off, what is hard for me to understand is how Tamron designed this lens at an incredible price point of $1,069.00. Have we really come this far in lens technology? Don’t look now, but 600mm f/4 Canon and Nikon’s run in the range of $9,800.00 – $12,000! Here is a viable option for 1/10th the price!
The image leading off this blog was captured about 30 minutes prior to sunset. This image was at the lower end of the zoom range (160mm) and was razor sharp.
It was my first indication that this lens was a serious contender for pros and not just an amateur lens.
- Sony A Lens Mount

The aperture range on the Tamron is of course variable, but in a very manageable range of f/5.0 – f/6.3. This makes it a perfect lens for landscape photographers, and a reasonable range for serious sports and wildlife photography.
I will admit, as good as cameras are nowadays in terms of limited noise at higher ISO ranges. I plan on testing further for sports (I don’t photograph wildlife) and will update this blog when I do. With my limited testing, I’d say don’t hesitate, this lens is up to the task!
Here are a couple images of my son Aaron during a recent practice session. Aaron is a serious golfer:
I photographed PGA golf tournaments for over 15 years. I would put these images up against anything I ever shot with my Canon’s and Nikon’s. The ISO on the Sony a7II is very clean up to 1600, allowing me a fast shutter. As you can see on both the front and backlit images, they are extremely sharp.
The front lit shot required very little post sharpening, while the backlit shot just a tad bit more. I had the lens mounted on a Gitzo monopod. This was actually my first attempt with shooting anything with this Sony and Tamron combination, and later found out, that by default, the in-camera stabilizer was turned on.
The autofocus worked flawless, and captured frame after frame o sharp images. It was also surprisingly quick coupled with the Sony a7II. Moreover, it was sharp on backlit images such as the one above of Aaron hitting out of a trap. This impresses me because autofocus relies on contrast, and backlit subjects are not contrasty, but as you can see, the lens’s autofocus worked beautifully.
I was also impressed with the sharpness of these images shot with a wide open aperture of f/6.3 through f/16! I would say the lens performed at its sharpest at f/11, but I would need many more tests to say that with 100% confidence.
Sony has confirmed that for images captured while the lens is on a tripod, the stabilizer should be off. It should be noted that the Tamron SP 150-600mm lens with the Sony mount does not have a built-in stabilizer. The Canon and Nikon versions do have a stabilizer built in to the lens. Interestingly, there is no difference in price between the three lenses! Without a stabilizer, I would think the Sony mount lens would be a bit less in price – not sure why that is.
It should be noted that I am using the Sony A-Mount to E-Mount Adapter with the translucent mirror. According to Sony the LA-EA4: Attach Alpha A-mount lenses to your E-mount full frame camera body and enjoy full-time continuous Phase Detection AF while capturing stills and video with world’s first full frame mount adapter to be equipped with Translucent Mirror Technology™. Plus, aperture drive mechanism enables Auto Exposure with compatible A-mount lenses3.
When shooting landscape images, I like to manual focus, and the lens manual focus ring moves in a very smooth fashion. I generally blow a portion of the image up in my EVF, and focus is easy and produces sharp edges in the viewfinder (assuming yo are focusing on elements that have sharp edges).
Here is a sequence of images starting at 200mm and progressively zoomed at 100mm increments out to 600mm. These were RAW files, with white, black, and midtones set to the same values. No sharpening was added in RAW – other than the tonal adjustments, no other adjustment were made. My focus point remained constant and was placed along the tree line:
I realize it’s hard to make a final decision based on JPEG images. But you should be able to see by the above sequence that the focus holds along the tree line beautifully all the way through the zoom range.
Personally, I love this lens and highly recommend it.
