***************
A---smc PENTAX-A ZOOM 1:4 70~210mm這顆鏡頭的好壞,我說了不算,請看用家評語:

Alan Chan - There are two Pentax A 70-210/4 . . . - one is SMC, and one is not. The SMC is the better one, . . . If it is the SMC one, the lens itself is printed "SMC" clearly.

- - - - - -

Ralf Engelmann - A good and optically brilliant lens, but mine had some mechanical problems with the macro setting. Pretty big compared to modern telezooms.

- - - - - -

Jerry Houston - I have a 70-210/4, and like it a lot. Since it's not an AF lens, the option was open to make it a "one touch" zoom, and Pentax did that. It is very convenient to use, and it was made at a time when Pentax lens build quality was about as high as it's ever been.

Unlike "two touch" zooms, this one has some limited depth-of-field information on the lens barrel. Optically, it's quite good. It's a little heavier than a typical plastic varifocal lens, but I'll gladly carry a few extra ounces in exchange for the solid construction, smooth functioning, and constant maximum aperture. Since it was designed from the start to be a manual-focus lens, focusing is smooth and precise. It feels and works the way a zoom lens should. . .

- - - - - -

Joao Vale - The Pentax-A 70-210mm f/4 zoom lens is a superb lens.I use this lens with both my cameras, a Pentax P50 and a Pentax MZ-5,and the results are very good.I do a lot off backpacking, and that lens is my favorite lens.The zoom is very sharp, and very resistant, I had never a malfunctionwith the lens.I have taken several thousands of pictures with this lens, with very good results, and the best thing is the price, . .

- - - - - -

David Cook. . . it's the first lens I have with full SMC coating, and flare is very well controlled. I took some slides recently facing directly into afternoon sunlight filtered through trees, a situation my other lenses don't handle well, and can see no problems. Also note that at 70mm it has a macro mode, focuses to 1:3 magnification, which I've found quite useful. . . it's the lens I keep on a camera at all times now.

- - - - - -

Tom Addison - The pentax 70-210 f4 SMC-A has consistently good reports from this group, I have one, I love it. It is heavy and really well built and the optics are very good for a zoom.

- - - - - -

Alin Flaider - stick with your A 70-210/4. None of the available AF zooms are a match for it. Brightness, constant aperture, focus kept while zooming, think twice before you trade all these for AF.

- - - - - -

Fred - The A 70-210/4 ~is~ a sharp, solid lens. The older Pentax SMC M 80-200/4.5 is also good, and is a little more reasonable in price (though actually harder to find sometimes).

Fred [again] - [ The A 70-210/4] has been my most used all-around nature photo lens for a long time . . .

- - - - - -

David Collett - IMO the 70-210/4A is the best short telephoto Penatx zoom that I have used. It is robust, makes nice pictures and has a constant aperture - what more could one want? If you see one buy it, you will not be disappointed.

- - - - - -

Cesar Matamoros - As a hobbyist that enjoys photography but has not gotten into the extent of blokeh, resolution, etc. this is my view of the lens. I presently own my second one. I retired the first after ten years of abuse. I have nothing but high praise for the lens. The photos I have gotten have great clarity to them. The lens is comfortable to use. I have used it with everything from an MX, SP, LX, to even a ZX-5. . .

- - - - - -

Mark Lindamood - I recently got an SMC-A 70-210 F/4 Zoom as part of a package deal and compared it to my SMC-M 80-200 f4.5, and found to my great horror, given the reputation of the 70-210, that the 80-200 was clearly sharper at 4.5 than the 70-210 was at 4.0. Color rendition was the same. The 4.5 is smaller, and the extra 10mm on either end is negligible. If you do not necessarily WANT an A lens, get the M. It's smaller, lighter, and better optically - at least my sample is.

- - - - - -

Bob Walkden - the SMC A 70-210/4 is a very, very good zoom, with excellent optical quality and superb build quality. It handles beautifully, particularly on an LX with attached winder. If this is the lens you're looking at then I recommend it highly. [and continuing that thought in another discussion . . .] In fact, for most purposes I'd recommend it over an f/2.8 zoom because of the greater ease of handling. The optical quality is 1st rate and it's very well built (make sure it's the SMC version).

- - - - - -

Collin - Went into [photo store . . .] They've got the A70-200/4 and the Tak-A70-210/4. So we put them on a body to compare. WHAT A DIFFERENCE -- even in the finder.

Mechanically, the Tak focuses much more quickly. Some might like that. It might be a result of the optical design. Visually, the A seems to have a larger circle of nonconfusion. That is, what is in focus is noticably sharper, clearer, and more distict as a result, at the same aperture & on the same body. While both are rated f4, the Tak-A appeared a hair darker. Probably more like a 1/2 stop difference. There's no comparison. AVOID THE TAKUMAR-A!

- - - - - -

Bill Peifer - This is one big, heavy lens -- 150 mm long and 680 grams. I bought one in very nice condition earlier this year . . . I love it. The glass was in excellent condition, . . . I like the one-touch zoom feature -- much quicker for action and candid shots than a two-touch zoom. One thing to watch for on these is looseness in the zoom/focus collar. The collar on some lenses will slip, thus causing the focal length to change, when the lens is pointing straight up or straight down. It's easy enough to fix -- simply roll back the rubber sleeve on the collar and tighten the screw. Another thing to watch out for is dust inside the lens. I'd stay away from any with internal dust. . .

There are some non-SMC 70-210 and 70-200 f/4 zooms. Don't confuse these inferior lenses with the SMC-A 70-210 f/4. They're not as high in quality or price. For more comments on the optical performance and a comparison with other lenses, see comments on Stan's site at http://www.concentric.net/~smhalpin/. . .

- - - - - -

Jim Brooks - . . . My A70~210 f4 was getting loose on the zoom / focus ring. Although the mechanism itself was nice and tight, the ring wobbled. After a little investigation I found that the ring is held to the lens mechanism by a metal ring about 3mm wide, fastened with four small (hobby-screwdriver size) Philips screws. This ring resides beneath the grip rubber at the camera end of the zoom / focus ring. There is no need to remove the rubber grip, simply peel back a few mm at this end. Tighten the screws (maybe add a smidgen of thread locker) and the lens is as good as new. Apologies if this is common knowledge but it saved me a trip to the repairer so it may help someone out there!
