Dear Matt and Mar,
After the Beijing trip, there was no surprise that the current a7iii was much better than the previous a7, my priority have always been autofocus, and that have vastly improved, the rest of the improvement is a boon, haa haa haa. I must say the eye autofocus is superb!
So far in my arsenal is the kit lens (28-70 f3.5-5.6) from the original a7, and 70-200 f4 (got this one purely to shoot your stage performance) now that over the years I have picked up some learnings, and with the new a7iii it felt right to start looking for a better walkaround lens.
Luckily there are more choices now than a few months ago, on the table were the following, Sony 24-70 f2.8 GM (~80,000 THB), Sony 24-70 f4 G (~50,000 THB) and Tamron 28-75 f2.8 (~30,000 THB). To be honest, I was struggling to choose between the three, lens is really a long term thing, camera bodies come and go, but lens do last a long time, unless they decide to change the mount, haa haa haa.
I must have watched a billion YouTube videos, and read a billion more reviews on all three lens, and all were pretty much consistent, considering the weight, the price, the f. stops, the Zoom range and the style, I had decided on the Tamron as my ongoing learning lens, of course I really would like the GM but this is not the time.
I kept going into dreamland, and have to kept reminding myself that this is to replace the walkaround kit lens, there are a lot more to learn before deserving the very top lens, haa haa haa.
I have had this lens for about a week now, that really means 2 afternoons of shooting (weekend, haa haa haa)... and so far so good, the lens came with the updated firmware and that saved a bit of hassle.
So where to next, I am still missing a prime lens, luckily Sigma have recently released their Art line lens with Sony FE mount, not to mention other brands that are already out in the market. I am still struggling on the focal length. The most typical walkaround lens would either be the 35mm and the 50mm, whilst the 85mm and 135mm would be more of a portrait lens, to be honest I am leaning towards the 35 :-)
