Tamron adaptall-2 70-150mm f/3.5 (20A) Test Shots

2016-06-28
Did some test shots of the Tamron (20A) while visiting Home Depot with Sony A7. The close up at 150mm goest to 1:3, quite handy for flowers.

The one-touch zoom design in this lens makes it quick to zoom and focus. I hope my test pictures help you a bit with potential buyers. Few things that I like about this zoom lens:
  • one-touch zoom design quick to reaction
  • small and compact, not like any 70-210mm MF zoom, filter size is 49mm
  • great close up down to 1:3, it can get to 1:1.5 if one gets the adaptall-2 2x tele converter
  • comes with a built-in lens hood
  • very reasonable in sharpness, ideal for Pentax use with SR, I find it more challenging to use on Sony A7 without SR
  • a cheapo alternative to DA* 50-135. It can't compete in quality to DA*, but I will prefer the smaller size in hiking and less bulk in street shooting
  • color and contrast surprisingly good
  • bokeh is decent for a zoom



Zonlai 25mm f/1.8 Ergonomics -- Sugru Focus Tab

This lens comes in handy on close up shot. I continue to run into minor issues on color and vignette on corners but overall I am quite pleased with the Zonlai lens. The 25mm is a sweet spot for me for casual street shooting, events, close up and hiking. Yes, I plan to take this as 1-lens out on hiking. With its good close up, this one will do well for me on flowers. The vignette and unsharp corners will be a concern to be tried out on casual landscape shots.

I am keenly thinking of trying out the Zonlai 35mm f/1.8 in black if I manage to sell off some of my other lesser used lens. I already have the Fujian 35mm f/1.7 but I prefer the build and compact form factor of the Zonlai. Do anyone know about the company behind the Zonlai lenses? There are a few other E-mount from Meike, Neewer or Kaxinda similarly re-rbranded E-mount and MFT lenses on 28 f/2.8, 35mm f/1.7 and 50mm f/2.0 but none of them look like the Zonlai as the Zonlai's aperture ring is in front and build look very different.

Ergonomics:
  • The aperture ring and focusing ring are very close together. It is very easy to change the aperture unintentionally when one adjust focus.
  • A focus tab is highly recommended add-on to this lens. I use Sugru from Amazon to mold a tab that becomes solid after a day.
  • With a focus tab, I find focusing much more precise and the tab helps to avoid inadvertent change on aperture
  • Other focus tab idea can be checked with lenstab in TAAB MINI | TAAB | Universal Lens Tab though I like the Sugru idea better as the lenstab will have the extra bend on top of your lens with potential in destroying the original beauty of the Zonlai.

2nd day with Zonlai 25mm f/1.8

Just a few words with caution on this lens as the wrong expectation will set you in the wrong path

Some negatives that I see in my research and brief usage:
  • Vignette does happen in the corners. I don't mind too much about vignette as I am center weighted shooting. More shooting experience will be needed to share
  • Though I have not tried, this lens may not be the right choice if your intention is on landscape and expect corners to be sharp across the frame
  • Color and contrast need tuning in post processing to get the best out of this lens
  • Color seem a bit odd in some shooting, if you love b&w conversion, this is your lens.

zonlai 25mm f/1.8 shares the similar size like the kit lens. My kit lens with JJC lens auto lens cap is placed inside the Zonlai box for reference.

All shot 2nd day into owning this lens with Sony A6000 and DIY added focusing tap with Sugru. I should have used Black Sugru instead of White Sugru.
