As a general rule of thumb, if the monitor has H/V 178/178 degrees viewing angles, its likely a IPS panel (can be of diff variants) but may not necessary display 100% colour. For eg, a mac 27" LED backlit monitor although using IPS panel, gives ~87%. People in labs tends to do correction unless otherwise advice, but as long as u like the results, then thats ok.
I have the Tokina 28-70 also, F mount. Quality not good le. The funny thing was when i bot it back then, the shop didn't want to sell me the Nikkor AFD 28-70, but instead told me Tokina is comparable & has the same resolution as the real thing. After using it, found that its far from the real thing, bot a Nikkor 28-105 later, & surprisingly its better than the Tokina. HAHAHAHA!!!
My monitor is the Samsung PX2370 which is 100% sRGB. Will get my friend to do some calibration but need to save original setting because I like what I see as I visit the FM alternate forum more often.
Seldom use my Tokina 2870 but seems to be pretty good value on my 5D. I hate AF inaccuracy and prefer not to use it if possible. I prefer my OM 35-70f3.6 manual zoom for travels accompanied by an OM 24f2.8 and my Zeiss 85f1.4.
