Canon EF 70-210mm f/4.0 telephoto Zoom lens
Marketed 1987 Discontinued: 1990

IF the earlier Canon EF 80-200mm f/2.8L may not be your cup of tea (an expensive cup, indeed..) Canon did offer a very interesting EF 70-210mm f/4.0 for consideration - interesting because unlike many EF lenses - it actually provides an unusual ONE-TOUCH zoom and focus control. The lens barrel has a marked zoom settings at 70mm, 100mm, 135mm and 210mm for quick visual guide during slide and pull action. It has an one f-stop slow maximum aperture, no UD glass, neither has USM for swift and quiet AF operation but the most attractive factor is its size, weight and affordability. For those who may has missed the entire generation of the manual focus Canon FD days, the zoom range of 70-210mm was first popularized by a Vivitar Series 1 70-210mm f/3.5 MACRO tele zoom - probably was also the first zoom lense which incorporated with an impressive close focus ability (1:4).

The Canon EF tele-zoom 70/210mm also matching with its magnification ratio at 0.24X (the previous FD 70-210mm @ 1:4) . The focus preset can be set to either MACRO-OO or 1.5m to OO with option to manual focus the lens. During macro focusing, the focusing index window will shown with an orange line. The infrared index also provide three separate indexes for 70, 100 and 210mm when it zooms. As the lens zooms via a single ring, the manual focus ring is rather thin - could have improved with a wider grip.

<<<--- It is a PULL & SLIDE Zoom.

The EF 70-210mm f/4.0 was also among the early batch of EF lenses launched with the EOS system but it didn't last long and by early '90, Canon discontinued its production and replaced it with a cheaper, very compact consumer grade EF zoom lens that comes with a variable aperture of f/3.5~4.5 USM in 1990. Those who found the EF zoom category of the early tele-zoom which actually comprised of a EF 50-200 f/3.5~4.5L or the fast speed 80/200mm f/2.8L and could be way too expensive for many consumers who may have bought some entry level EOS SLR, so one may find alternate EF 100-200 f/4.5A, EF 100-300mm f/5.6 (L) as consideration. The lens DOES NOT has a USM configuration - instead, it has an EF Electro Focus Arc-Form Drive (AFD) and features Electromagnetic Disphragm control only. Optically, there is a little surprises, as optically, it has a molded Aspherical element inside. Based on the simple 11 Elements in 8 Group optical, the claim may has some basis.

Canon EF 70-210mm f/4.0 by mayskyold@EBAY
Although the EF 20-210mm f/4.0 may not pack with too many fancy gadget, but it is very usable for many photographic usage. For the serious users who may prefer to look at the spec sheet - according to a read from Gunter Spitzing's EOS-1 user guide (Hove books) he claimed this Canon tele-zoom was among the "most popular" EF tele-zoom lenses sold back in those days. As most early EF lenses are solidly build, so does this lens, a solid stainless steel EF mount...rare treat.

Canon EF 70-210mm f/3.5-4.5 USM
Marketed: 1990 Discontinued: ~

When Canon replaced the EF 70-210 f/4.0 featured above, they actually fixed the retail price of this new replacement the same with the old lens. Is that any justification for a smaller variable maximum aperture lens when the zoom range changes ? I don't know. But other than the compromise on a dimmer maximum aperture and reverting to current DUAL zoom/focusing ring design, the lens is smaller than the predecessor and - looks more solid. Another premium was an addition of a USM from the AFD used in the previous version. The zoom ratio is marked on the lens barrel with 70mm, 100mm, 135mm and straight to 210mm. The grip has an updated design but the focusing ring is smaller than ever. Further, a tiny orange MACRO symbol is printed next to the display window as a guide when the focusing index line turns yellowish-orange as well. The infrared index has eliminated the 100mm setting and retaining only two at 70 & 210mm respectively.

Canon EF 70-210mm f/3.5~4.5 USM
It is a 3X telephoto zoom ratio lens, featuring a built-in Ultrasonic Motor and a middle of the road maximum aperture which mainly contributes to its compact size. Besides, the small dimension of the lens was achieved using a newly-designed five-group zoom lens construction internally. By utilizing the 4th lens group in a rear focusing system, spherical aberrations are minimized and sharp, high-contrast image quality is realized throughout the zoom range.

<<---Credit: Phoon Photo, Ipoh for lending me the lens for taking the few photos shown in this site. Slightly distorted with the tiny Sony compact at close focus. hehe ..

Despite the compact size, a close focusing distance of 1.2 m/3.9 It is attained at all focal lengths and a magnification ratio of 0.17X is possible - at the useful, longest 210mm setting for less distortion of perspective. Excellent operability is achieved through use of a wide zoom ring and an Ultrasonic Motor which provides fast and silent autofocusing and allows manual focusing at any one time for fine focusing while the lens is in AF mode. Its metal lens mount at the rear section separates this lens from many cheaper EF zoom that comes with the hardened plastic mount. Overall, given the budget and combining with its performance + lease in handling, I like this lens

This lovely lens makes a very good combination if you intend to built a two lenses system with either, an ultrawide or wide to mid-tele range of zoom. But as the Canon EF lens group expands in its many varieties and type with the commercial consideration of minimizing overlapping focal length; it was eventually being phased out in the product chart. Lense like the EF 70-300mm f/4.5~5.6 or the cheaper EF 75-300 group makes this lens less appealing to cost conscious consumers who seek for better value in a more extended 4X + zoom ratio. Doubting me ? just take the EF 75-300 f/4.5~5.6 MK III - it has evolved into its third phase of upgrade while IS (Image Stabilizer) has also been installed in the EF 70-3-- f/4.5~5.6 DO IS USM....good news is, since it has been phased out, prices in the used market also falls accordingly, on a recent search via Ebay BUY IT NOW - I have found this lens retailed fore USD 225-00 while a comparing EF 70/300 IS USM asked for USD600-00, DO IS USM version is around USD1,100-00; while all these make the older lense comes with an exceptional value.

Officially, when Canon first shown the photo community with the worthy upgrade of EF 70-200mm f/2.8L in 1995, they have indirectly created a new trend setting zoom range on their own as the previous 80-200mm as well as 70-210mm were more like "somebody's" innovation. Unless I am wrong with Canon pull off with some surprises, this EF 70-210mm f/3.5~4.5 USM could have been the last of its kind in the EF lens group, I guess.
