Hard to tell, since only the second pic is in high resolution and can be zoomed, but according to some other forums another set of sensors were added to the sides and the bottom of the cockpit:

Sir, are those IRSTs?

Or are they EOTS like that on F-35?

What are those sensors used for? Tracking of targets or as a substitute for the pilot vision?

If they are IRST, then I think FGFA will have that 360-degree infra-red surveillance capability achieved for
the F-35 by the Grumman-developed Electro-Optical Distributed Aperture Systen (EO-DAS).

Is there any difference on the rim of the nozzles of T-50-4 and T-50-1? Or is it just a trick of the light?

Sancho is more than enough.

No, the IRST of Pak Fa is similar to the older Flanker versions on the nose and EOTS is an integrated targeting pod with IRST functions, while we have seen a dedicated Russian LDP for Pak FA on the last MAKS air show:

They could be the additional optical sensors of the 101KS system, which includes IRST in the front, MAWS behind the cockpit and additional sensors around the airframe, but so far it wasn't clear where they would be fitted:

No the nozzles are the same and might change only with the NG engine, only the tail sting differs in these pics, but they have tested different once.

Some closeup pictures of the device are here
Unfortunately translation is not working. The device by looks of it looks like an optical sensor.

The placard does have description written over it. Can some Russian mate help in translation.

Is there L band radar behind LEVCON ? There is something behind LEVCON !!!

As per both picture the tail also different, the new one more shaped for LO, MEANS those long tails will be there in the final version too?

@sancho do you not think that the IAF would like to intergrate a Western LDP for their FGFAs?

Hopefully not, because it's silly to use an external LDP for a stealth fighter that carries it's LGBs internally. I hope we go for an internal version, maybe based on the Litening techs and with Rafael, but external carriage is not the way to go.
