50mm f1.4 vs f1.8?

[woof woof]

I watched this vid some time back, the interesting bit starts at about 1:50, and this made me think that the older lens effect might actually be as good or maybe better for video. I think it works really well in this vid and maybe more so than in a series of still pictures as in the vid you see the effect came and go and it all looks quite natural. Maybe The lens he uses is a bit expensive and you could maybe get a similar flare look from something cheaper.

Anyway. Enjoy.

So following on from the Sigma 85mm focus shifts between shots in burst mode I think it's down to the tracking modes. I tested it on my syderlenscal and in AF-C single point the focus never shifted, but in AF-C tracking single point the focus shifted between shots. I guess this is to be expected as it's in tracking mode and assumes the subject is shifting, however not ideal if shooting static portraits and you want to use realtime eye-AF single point expandable focus. I'll have to play about when my wife's feeling better and will be willing to let me stick a camera in her face.

As I mentioned before it's not horrendous as shown by these two sequential shots in high speed burst, but may be the difference between focus on the eye and focus on the eyelash. The focus shift did look worse in real world examples yesterday and the focus area wasn't sharp unlike here.

If it assumes the subject will move and this causes it to be slightly off will waving the camera about ever so slightly cause to hit focus more often?

Just wondering
