Clarifying The Sony LA-EA1, LA-EA2, LA-EA3, and LA-EA4

Sony has a lot of great new and used Minolta A-Mount glass that is being forgotten about as more Sony photographers more to E-mount from Sony’s legacy A-Mount standard. Sony’s A-Mount translucent mirror technology has always interested me and when it was introduced there was a lot of value in Sony’s lens line up, but I decided to go m43 around that time since it was truly mirrorless and compact.

Now prices are still high for new A-Mount glass, but if you look carefully there are some great used values that should only get better with time as more photographers switch to native E-Mount glass. There are a variety of reasons why a photographer might switch their A-Mount to E-mount glass, but if you choose your adapters wisely switching to native E-Mount glass is less of an advantage than you might think.

In my estimation, Sony’s adapters that come with a screw drive and translucent mirror are the best option, but if your camera has on-chip PDAF the translucent mirror becomes useless beyond having a screw drive motor in it, but that is the cursory explanation. For a more nuanced explanation watch the video above to see how the Sony LA-EA1, LA-EA2, LA-EA3, and LA-EA4 operate differently and the video below to see how they perform when shooting video.

Tamron 17-28mm f/2.8 Di III RXD FE Review

Dustin Abbott posted another of his lengthy reviews that is broken up into three parts about the Tamron 17-28mm f/2.8 Di III RXD FE. Below are excerpts from the videos:

  • The 17-28mm is well built and very light
  • Fully weather sealed
  • Very well designed
  • Not great for manual video
  • Video AF is good and silent
  • Great AF overall and it is one of the quietest lenses Dustin has ever used
  • There is some strong budge/barrel distortion and vignette at 17mm, but it is well corrected in JPEG and easy to correct the RAW
  • For real-world landscape, there isn’t much distortion or bulge so it gets better when the focal point is distant
  • The Tamron is very sharp at the center of the frame with good contrast wide open
  • Tamron is pretty good in the corners wide open, but a little soft
  • At f/5.6 the center is spectacular and it sharpens up in the mid-frame and corners
  • Once you get to 20mm there is a little pincushion distortion and vignetting gets much better
  • The Tamron at 20mm looks excellent at the center and the midframe and corner is performing well wide open
  • 20mm at f/5.6 fantastic center and mid-frame with the corners looking good
  • 24mm has a little pincushion and vignetting is not an issue
  • 24mm looks very good at f/2.8, but the resolution does get a hair better at f/5.6 very good result overall
  • 28mm is a little wider on the 17-28mm than on the 28-75mm lens
  • The 17-28mm has a little pincushion distortion at 28mm
  • The 17-28mm is fantastically sharp at 28mm, but the 28-75mm is a little sharper
  • There is a little softness on the 17-28mm and 28-75mm at the corners
  • At f/5.6 both Tamron’s are sharp in the middle, but the 28-75mm shows some more contrast
  • The extreme corners at f/5.6 are good, but not excellent
  • This lens is well designed for landscape photography because infinity focus has minimal issues
  • The Tamron 17-28mm has lots of micro-contrast and pop at infinity wide open and stopped down
  • A little ghosting pattern with the Sun in the frame, but the contrast is still solid and it makes the image look more artistic
  • Starbursts are good and bokeh is pretty good
  • Image quality is solid at 28mm up close
  • Crisp star points for Astro with minimal chroma problems
  • Good lens for Astrophotography at 17mm, but not exceptional
  • Chroma is a hair worse at 28mm
  • 17mm can focus closer than 28mm and contrast and resolution are great here
  • 28mm close focus has a little less magnification, but the contrast drops off a little
  • Hopefully, we will see a lens profile for 17-28mm RAW files from Adobe soon
  • Video is corrected in-camera for distortion and vignetting
  • The only comparison the Tamron lost was against the 28-75mm Tamron at 28mm
  • The Tamron 17-28mm and 28-75mm can replace a lot of prime lenses
  • Had a few AF glitches that require the camera to be reset so might need a fix like the 28-75mm
  • The 17-28mm cost less than half of what Sony’s wide zoom G master does and it’s even less than what Sony’s f/4 wide zoom costs while offering superior performance

Tamron Will Announce Four New Mirrorless Lenses Coming Soon


Tamron posted some teasers to their social media that hints at 3 new mirrorless lenses coming soon. It looks like one will be a telephoto/zoom maybe a 75-210mm along with 3 prime lenses. If they release a 70-200mm type zoom for e-mount than they will complete their lineup with the 17-28mm, 28-75mm, and a 75-210mm. Tamron zooms have been incredibly popular on E-mount and are still often sold out.

Kai on The Sony ECM-B1M Shotgun Mic

Kai compares the new Sony ECM-B1M Shotgun Mic and Rode Shotgun Mic and it holds up surprisingly well. It’s interesting that Kai thinks the ECM-B1M is being under-covered because I have seen a lot of reviews out there but to vlogers the new Sony ECM-B1M should be as exciting or even more exciting than the Sony a7RIV announcement. Now Sony just needs more cameras for the Sony ECM-B1M to work with, which we should see soon.
