Latest Review Posted | Takumar 135mm F2.8 Bayonet I can't really put a full review of this lens here as I do not own it and never have.
But I wish to make a few comments.
Basically this lens is the same as the SMC-Pentax version except for the coating.
In some light-conditions it can give the same good result as the SMC-version.
When light comes in from the wrong angle however it can lose contrast, give flare etcetera. This can be suitable for dreamy portraits.
If one remembers that in the '50s and early 60's lenses did not have multicoating either, it is clear that a lens like this can be used to create a similar effect.
That said, it is easy. Learn what the lens can do and cannot do. If you need a flare-free lens that gives always crisp images go for an SMC-version. If you want to use the effect, or cannot afford (then) or find (now) the SMC version, this one is a good choise.
The 2.5 version can be expected to be slightly better than the 2.8 version.
The 1.8 star and 2.5 (SMC) were top of the bill then whereas the 3.5 (both 3.5 K and M versions) and the more recent 2.8 (A, F and FA) version were clearly the cheaper (but still good) counterparts for the average user and for those that needed to travel lighter. |
