I would like to know your thoughts on aquiring a new lens for my 600d.
With the lens I would like to do some low light and strob photos, also but not that much street. It should be also useful for video (manual focus capability).
I would like to have some nice sharp images and a nice oof background. What would you recomend?
I also considered the Samyang 85mm 1.4 but I really do not know how is it to focus on a 600d with the stock focus screening, which I am not willing to replace.
I know 50 and 85 are quite different focal lenghts and actually I already have the sigma 17 50, which makes me quite happy, but sometime the f 2,8 does not deliver the oof I wish.
Thank you for your advices.
On a full frame the focal lengths are different animals. But on a crop such as yours they are more alike (excluding the brand name and IQ and sticking just to focal length) in that they will both fit the portrait genre. They will fall on the lower and higher end of the "medium" tele lenses on a crop sensor. So depends on if that is what you intend them for. Indoors they both will be a tight fit on a crop sensor for groups of people. Head shots they are perfectly suited for. The 85mm on crop would be similar to 135mm on FF so outdoor portraits etc are doable and perhaps some ambient light sports too.
