Hi, would anyone upgraded to 2.0 please check whether the RAW file is compatible with current version of Adobe Camera Raw or not? Thanks

Thank you all for the valuable information! Now I realized that perspective is one reason that the 35mm can't be used for portrait. I will take 50mm f/1.4 for both portrait and low-light shoots.

I'm pretty new to photography so it's great to have your knowledge and experience shared!
Wish all a nice weekend!

I just don't think 35mm will be a good portrait lens.  If you have the f stop down pretty low, say 1.4-2, it will be impossible to get a whole group of people all in focus.  Secondly, if you buy a 50mm prime, that's 80mm on a 1.6x, and that is actually not far away.  So actually a 50 would work really well.  If you still have your 55-250mm zoom lens, set it to 50mm and test it out to see what I mean.  35mm on a crop 1.6 is 56mm, so yes, that lens works but I have had a hard time getting everything in focus when the aperture is really wide.

Thank you for the reply, but I don't really get you point: you suggested me to get 50mm, either 1.8 or 1.4 will have wider aperture and longer focal length compare to 35mm f/2, so the effect must be shallower DoF, and harder to get focus with wide aperture.

In previous post I just wonder will 35mm f/2 with its wide open aperture could produce shallow DoF like the 55-250mm or not. In other words, DoF is more depend on aperture or more depend on focal length?

You are right on the 50mm that it is not too far away. I will check it out for considering

I have another question: I intend to sell my Canon 55-250mm f/4-5.6 to buy Canon 35mm f/2 for portrait shoots (separation of subject from background is important to me). However, I don't know if f/2 of the 35mm can create shallow DoF like (or better than) the 55-250mm with long focal length or not?

I use crop sensor and don't want to move to far from subject so the 50mm f/1.8 or f/1.4 or longer focal length are not suitable for me.

Any advice for me on that? Thank you very much!
