Canon EF 70-200mm f/2.8 L IS USM Lens

Product Information

From there, the 200mm and 300mm fab markets are subdivided into two categories — integrated device manufacturers (IDMs) and foundries. IDMs design their own name-brand chips and manufacture them in their own fabs. Foundries manufacture chips for other companies in their own fabs at competitive prices. Most foundries have both 200mm and 300mm fabs.

Despite the migration toward 300mm fabs, 200mm plants didn’t disappear. On the contrary, a large number of chipmakers continued to produce chips in older 200mm fabs. Today, many vendors also make chips in older 150mm and 100mm fabs. Indeed, there is a perception that the requirements are simple for chips in 200mm fabs. On the contrary, the requirements are sometimes complex and device makers want tools with more precise processes and faster throughputs. The 70-200mm's zoom ring sits at the front of the barrel, so you might have to fight some muscle memory if you're used to a more common mid-barrel placement. It didn't bother me too much, but I frequently swap from one camera system to another. (Credit: Jim Fisher) The 70-200mm F2.8 falls short of competitors in one area—macro photography. The Tamron 70-180mm G2 and the Sony FE 70-200mm F2.8 GM II focus closer, for 1:2.6 and 1:3 magnification, respectively. The Sigma 70-200mm F2.8 manages 1:5.2 at its 200mm focal length and 39.4-inch minimum focus distance, so it matches up more closely with the Lumix S Pro 70-200mm F2.8 and its 1:5 macro focus. The lens focuses to 25.6 inches at 70mm, but the wider angle results in less magnification. For macro photographers who don't mind an F4 zoom, the FE 70-200mm F4 Macro G OSS II is the best in the class thanks to its 1:2 reproduction.

The new Nikon Z 24-200mm lens can focus even closer, at about 70 cm (2.3 ft). It can focus much closer than the old 70-200mm lens but the reproduction factor is about the same (I believe this is due to focus breathing?). Here is an example of a waterlily photographed with both lenses at their minimum focus distance.

Specifications

A new 200mm foundry player, Key Foundry, entered the market in September after acquiring the foundry business from MagnaChip. This is what I have to say about this lens. I hope this is helpful to you and you can make your decision about getting this lens or not. Sample photos made with NIKKOR Z 24-200mm f/4-6.3 VR lens When attached to a non-stabilized body –the Canon EOS R, Canon EOS RP or Canon EOS Ra–this lens delivers a solid 5 stops of stabilization. However, mount it to the IBIS-enabled R5 and R6 and the combination IS delivers an enormous 7.5 stops of stabilization –that's half a stop less than the RF 70-200mm f/2.8L, but is still incredibly impressive. Another way to look at capacity is fab production, which is measured by wafers per month (wpm). “In terms of wpm, we see a steady growth of about 3% to 4% each year from 2019 to 2021,” Dieseldorff said. KLA, Onto, and others sell inspection and metrology equipment, which is also critical in 200mm fabs. Inspection equipment finds defects in chips, while metrology tools are used to measure structures.

Sigma's Sports designation for the 70-200mm F2.8 indicates it's ready for action, for everything from wedding receptions to sideline photography. The lens features dust and splash protection for work outdoors in inclement conditions, and its front element has a fluorine coating that repels water droplets. The internal zoom further cements the 70-200mm Sports' pro-grade zoom caliber. This type of design draws in less air during zooming actions, so there's less chance of dust getting pulled into your camera versus with a telescoping lens. The conversion factor from mm to inches is 0.0393700787. To convert any value of mm to inches, multiply the millimeter value by the conversion factor.One noteworthy positive is the impressive close-up capability. While you’ll get the closest focus at wideangle, you’ll get the highest subject magnification at telephoto, and with a decent working distance too. This is handy if you want to avoid disturbing skittish subjects. Dimensions can be a bit nebulous when you just read them out. So to put them into context, not only can you stand the RF 70-200mm f/4L upright in your normal camera bag –you can also mount it to your camera and put the whole thing into a small sling bag.And that's just crazy. Another source is the secondary or used equipment companies. These companies obtain cores and refurbish them. Some even build their own name-brand tools. In terms of design, the FE 70-200mm F2.8 GM OSS II features the standard white body of Sony’s telephoto lenses and an internal zoom mechanism which means the lens remains a single size.
