Description:
"A moderate wide angle to moderate telephoto zoom lens with above average optical performance. This lens is more compact than the earlier model 22A and features a completely new optical design which retains a floating front focus group as used in the earlier model 22A optical design. This lens trades off the earlier model's CF macro ability at 135mm in favor of a significantly more compact overall design. Maximum macro magnification (pic 3) is achieved at 35mm by using the built-in macro button and turning the macro helicoid ring, an operation which is similar in function to Tamron's SP 28-135. Although the macro function is less convenient compared to the earlier model 22A design (extended focus throw at 135mm), this lens is more compact and uses smaller filters". - Adaptall-2.com

Lens Review Date: May 29, 2014 I can recommend this lens: Yes | Price: $20.00 | Rating: 9 

 
Pros: Good images, good handling, across full zoom range
Cons: If you can find a use for the macro mode, let me know ...
Sharpness: 9    Aberrations: 9    Bokeh: 9    Handling: 9    Value: 10    Camera Used: Samsung GX20, Pentax K-x   

I own two copies of this. One cost 12.50 euros with no caps and a Tamron Adaptall C-mount (useless to me), the other £17, including a PK mount, caps, case, instructions and the retail box. The price shown above is the average of the two.

This second one (actually, the first I acquired) had a modicum of fungus on the second element from the front. The front element comes out easily, and I cleaned the fungus off, but after a year or so it's growing back .

But apart from this minor issue, both copies look like new, and both are spectacular performers. Nice, rich colours (though not as rich as the Pentax PowerZoom 28-105mm f4-5.6) quite sharp wide open, very sharp stopped down to f.8, good sharpness and contrast across the whole frame, across the entire zoom range, near and far. Whilst not as good as the prime CZJ 135mm f3.5 at 135mm, the comparison doesn't embarrass the 40A.

Good unobtrusive bokeh, and I don't notice fringing or aberrations generally.

The 40A takes wallet-friendly 58mm filters.

It balances nicely on my cameras.

I use a screw-in petal hood, and find the 40A to be much less affected by flare than my 01A.

For walking around town, the zoom range isn't that convenient; I often want to go wider than 35mm, whilst I seldom want to go as long as 135mm. But for a walk in the country or a day at the beach it is excellent. Even my old eyes can focus it accurately when it is bright and sunny!

Any drawbacks?

Well, the macro mode engages at the 35mm rather than the 135mm end, so you're almost touching the target, and the macro image quality doesn't stand comparison with what the lens ordinarily achieves.

And obviously there's no autofocus or automatic image stabilisation communication to the camera body, which certainly at the beach is a drawback.

But I would be very upset if the beach killed my PowerZoom 28-105; at the prices these go for, there's no reason not to have a spare!

A worthy 9, I think.

Lens Review Date: April 6, 2012 I can recommend this lens: Yes | Price: None indicated | Rating: 9 

 
Pros: Sharp-ish, lighter, smaller size & filter diameter, value
Cons: Rotating front element, quasi-plastic feel
Sharpness: 9    Aberrations: 8    Bokeh: 8    Handling: 9    Value: 10   

Bonjour,

Based upon pacerr's review (above), this lens went to the short-list for a future acquisition ... and lucky me, I found one last weekend at the Montamisť photo expo/swap meet event. I paid only 10 Ä ( approx. $ 14.00 ) for this lens ... with the original front cap and an OL mount & rear cap! Given this price is extremely low, I have not put it into the database info.

My copy is in good condition except for a very minor scratch on the front element and some dings on the exterior of the filter ring area ... this lens has is some duty. I have attached photos of it with its predecessor version, the 22A which I had first and reviewed here: https://www.pentaxforums.com/userreviews/tamron-adaptall-2-35-135mm-f-3-5-4-2-22a.html

As for the performance of this lens, pacerr said about everything and I cannot add too much. The 40A is lighter and smaller in many ways, and the IQ seems to be slightly better given my impressions of the first test shots. The 22A is better if you want a "macro" (only 1:4) or close focus capacity that gives you a greater working distance from your subject (about 0.8m). If you want to capture photos of butterflies, bugs and bees, then I would not suggest the 40A ... IMHO, you'll be too close (0.28m) given the "macro" is at 35mm.

Here's the link for the 40A on the "adaptall-2.org" site - http://www.adaptall-2.org/lenses/40A.html

Hope that this helps ... both are good lens. your choice may depend upon your needs, etc.

Allez & bon courage, John le Frog

Lens Review Date: September 1, 2010 I can recommend this lens: Yes | Price: None indicated | Rating: 9 

 
Pros: small, light, great value
Cons: mid-1980s plastic build
Sharpness: 9    Aberrations: 8    Handling: 7    Value: 10   

This lens is a direct replacement for the Model 22A . As much as I appreciate the build quality of the older lenses, this newer version has it beat in every way. Physically, itís smaller, lighter and uses smaller filters. Optically itís been reported to have better contrast and sharpness at all f-stops and focal lengths.
One operational difference, where the 22A was continuous focus into the 1:4 macro range at 135mm, this one does 1:4 macro at 35mm with the same minimum distance of 31.5Ē (0.8 M) using a macro switch on the lens. Focusing and zoom are buttery smooth.

This is another of the economy zooms produced in the mid 1980s to compete in the market against the new auto focus consumer bodies and lenses. The compromises were in the use of more economical mechanical assemblies and the use of molded rather than machined parts. In my experience, the optical qualities of this lens could well be considered SP-quality. Compared to an FA 28-105/4.0-5.6 (Tamron design) or the Tamron SP AF 24-135 (190A) I prefer this lens for crisp, saturated color and general sharpness in normal outdoor use.

In a choice between the two, I ultimately kept this lens over the convenience of the much larger, auto focus 190A. In many respects, I feel it gives results similar to the Pentax 105/2.8, 135/3.5 and 200/4 at the long end.

If you already have a PK/A adapter, or want to invest $20 in a PK version, the $20-30 youíll pay for this on eBay is a real bargain and if you can forgo auto focus for a day this one will delight you in the field as a poor manís DA* 55-135. I compare mine with the acclaimed SP 35-80 (01A) and find little practical difference at one fourth the going price.

I'm giving this a 9-rating to reflect it's excellent value at the going eBay prices as well as it's image quality potential.

It pairs very well with the AD-2 28-70 (40A) and with a 25mm extension ring these two lenses make a very versatile outdoor/nature kit that can be put together for less than $60 today.
