Low-cost lens cavalcade #10

Now we come to the last of the ten (usable) lenses I got in the great deal, the Asahi Pentax Super Takumar f3.5 135mm.

Saving the best for last.

This is a lens I’ve wanted for a long time: it is the ‘missing’ member of the ‘standard trio’ of lenses for my Pentax Spotmatic 1000. Back in the day when I was using this as my main camera I managed to obtain a (radioactive) 35mm Super Takumar wide-angle to go with the 50mm standard lens, but could not afford the 135mm version. Instead I purchased a much cheaper 135mm f2.8 Vivitar, which I still have. Now through the good fortune of one deal I have the Pentax telephoto. There are longer Super Takumar lenses, and shorter ones too (I also have a 28mm), but the combination of 35-50-135 was considered a ‘proper kit’ of lenses in that age of film SLRs. There is also an f2.8 version of the 135mm, but that is not the one I have found.

So let’s see how well it works.

The next photo was taken on a cloudy day, yet contrast and colour are good. Sharpness is nothing to complain about either, and no sign of chromatic troubles. But let’s push the limits.

Now when we do the digital zoom thing we see sharpness falling off and chromatic troubles arise. Not as bad as some of the other lenses recently tested, though. But is this how the lens would typically be used?

If you don’t zoom in digitally everything is fine, especially in bright light when you can stop down to f8 (the ‘non-existent’ sweet spot for this lens). I shot quite a few ‘standard’ pictures and found it to be more than adequate under normal conditions.

The lens can do quite well.

Although 135mm is quite short for my usual photography I can see there are times when this lens would be just the right thing.

When all the elements come together …

I rate this lens as very good. Even though the performance has some shortcomings, they only appear when it is pushed to perform under less-than-ideal conditions. What’s more the actual handling of the lens (focus and aperture rings) is the usual high-quality of Super Takumars, so I have no complaints on operation.

Well that’s the last of the ‘deal lenses’. Of course they were not all the equipment I got in the deal, but much of it really isn’t of any use to me. The question remains: was all of it together worth the money?

Notice I haven’t yet revealed how much I spent.

What did I get that I will continue to use? A couple of cases and three lenses: the 28mm Vivitar, the 58mm Helios, and this 135mm Super Takumar. Now, what is a lens worth?

One of the on-line sources I follow has posted a list of “the best M42 lenses for $150-$300”. That’s per lens, and even the low end is expensive by my standards. Okay, I’m a cheapskate. So what would you be willing to pay for any one of those lenses (assuming you wanted one of them)? Half the ‘starting price’ mentioned in the article (i.e. $75) perhaps?

How about $60 for the whole boiling?

Come to that, I’ve probably had that much money’s worth of fun playing with the lenses and other things.

And I intend to have more fun with some of it in the future.
