Da* 200mm f 2.8 vs da* 300mm f 4 i'm starting to save up for my first top notch expensive lens and i think i want to make it a long telephoto prime. On the contrary, a large number of chipmakers continued to produce chips in older 200mm fabs. Main advantage is extra reach, but only very slightly.

Or, at the same distance, things in the viewfinder look 50% bigger with the 300mm lens.
Despite the migration toward 300mm fabs, 200mm plants didn’t disappear.
Ic insights believes there is still much life left in 200mm fabs because not all semiconductor devices are able to take advantage of the cost savings 300mm wafers can provide. At 300mm, it is about 8 degrees. To similar to what you have to justify the downsides (weight, cost, size). 100 mm to inches = 3.93701 inches.
200 mm to inches = 7.87402 inches.
My primary love is wildlife/outdoor photography but living in downtown portland i've adapted a. 200mm = 7.7 degrees = 20.1 ft 300mm = 5.1 degrees = 13.4 ft. This will be for my 17 year old daughter that likes to take pictures and then play with them on photoshop. In other words, at 300mm, the image captures a narrower part of the scene compared to at 200mm.
Initially, the cost to build a 300mm fab was $2 billion to $3 billion.
“in general, the wafer area of 300mm is 2.25x larger than 200mm.” initially, the transition to 300mm fabs was difficult, but eventually the migration paid off. Another way to put it is that a scene that looks right at 200' with the 200mm lens will look right at 300' with the 300mm lens. For the same photo composition you can be 50% further away with the 300mm lens. This may help explain your subjective impressions.
So (at 50 yards) going from 200mm to 300mm only reduces this size of your frame by about 7ft, wheras going from 100 to 200 reduces it by 20ft.
Prior to 2008, the 200mm wafer was used in more cases for manufacturing ics than any other wafer size. 40 mm to inches = 1.5748 inches. However, since 2008, the majority of ic. Fabs running 200mm wafers will continue to be profitable for many more years for the fabrication of numerous types of ics, such as specialty memories, display drivers, microcontrollers, and rf and analog.
Fewer ic makers use 300mm wafers vs.
Obviously, the main difference between the two is how far you can zoom into the subject. 50 mm to inches = 1.9685 inches. Beyond 300mm, the same gain requires a jump to 450mm wafers.
