I have just returned by Samyang 85 1.4 due to aperture spring issue. And, i dont want to buy that again.. as i heard it is a common issue with this lens (I live outside US and difficult to return it everytime
)
Now, i want to invest in a new lens.. but not sure which one. Below are my current lenses
Pentax 16-45 f4
Pentax SMC M 50mm 1.7
Pentac DA 55-300
and bunch of m42 50mms from various brands
I always wanted to try ultra wide lens... but after buying 16--45, i kind of didn't like that and if possible want to switch it with sigma 17-50 f2.8 -> thats one option
I really liked the m 50mm 1.7, but the only con is the manual focus.. I am shooting parties these days and it is very difficult to focus in the low light. So, i want to invest in auto focus.. but not sure which lens will be optically identical as the SMC.. FA 50mm 1.4 ?
I also want to try my hand at portraits, that is the reason i bought samyang.. too bad it didnt work out. Are there any other lens which are as good as this one ?
Finally, my budget is 500$. and, i want to invest in a lens which will stick with me for some time. Please, suggest
