It’s odd because you have now criticised a second lens (28mm f2) that I’ve been looking into that in the whole has very good reviews online, getting 4/5 and above. I appreciate you probably have hands on experience but I wonder why your views are so critical? Likewise the Tamron are getting 4/5 and 5/5 with many commenting how sharp they are.
As for looking at f1.4 I missed that bit
Just like I criticised the 24mm Samyang you mean?
Look how that worked out for you.
There are good and bad lenses within every system I base my opinion only on what I have used or will say I don’t know if I haven’t used the lens.
As I am a working photographer and sometimes work on projects with other photographers I get my hands on a lot of gear and multiple copies of most gear.
Based on that I know that the Sony 28 f/2 and the 50 f/1.8 are not very good.
I also know that the Samyang 24mm, 35 f/1.4, 50mm f1.4 are also not very good and that the 85 f/1.4 is sort of okay but wouldn’t be good enough for me.
Other lenses have there pluses and minuses.
My opinion shouldn’t matter to you though. I wouldn’t make a decision on buying something based purely on what people in this thread say as my needs are very different from there’s.
As for the Tamron primes as I said I haven't used them but the other photographers I know that have used them don’t rate them compared to the other options available. Also everything I have read about them on the wedding photographer groups on Facebook suggests they are not very good compared to other options. I trust the opinion of those people much more than people on here or on YouTube because I know quite a few of those people in real life and respect their opinion.
There are quite a few people in this thread that will say stuff is good or bad based purely on a YouTube video they have watched. There is even people in this thread that give recommendations and opinions even though they have never touched a Sony camera and use a completely different system.
I don’t trust online reviews, YouTube etc at all I would rather speak to someone with hands on experience. I know how the reviews are manipulated by the manufacturers, I have been offered incentives by some of them myself.
