Yuk. Sorry to hear this, I emphasise after dropping and shattering a lens's glass last year...it was very upsetting.
Time for my feedback on the Takumar 50/1.4s....
For the first half of the month I used a Super Takumar ('ST'), early 8 elements version. A lens designed to rival the best Zeiss/Leica lenses from Europe. Legend has it was so expensive to manufacture it was soon discontinued in favour of the 7 elements version. (This is now disputed by people involved).
For the second half, a Super-Multi-Coated Takumar ('S-M-CT'), 7 elements version. This lens is infamous for being radio-active, with thorium coatings producing a yellowing of the glass that can be reduced by UV light. In case you don't know how radio-active this lens really is, have a look at this video! The highest radio-activity is by the eye.
Other yellowing radio-active lenses include the Zeiss Pancolar 50/1.8 zebra 8 blades, and the Takumar 35/2.
Performance wise from this month's photos I found my ST slightly sharper wide open than the S-M-CT, with creamier bokeh, but less vibrant colours. Stopped down the lens delivers a 3D look that owners rave about, especially for portraits. I think this is because the centre is sharp while the edges and bokeh are softer, and overall the colours across the frame are cooler, so the background does not stand out. Downsides? May need PP to bring out the colours and minor PF sometimes.
My S-M-CT is even sharper than the ST stopped down, with better flare control and such vibrant colours. Indeed the colours this lens produces on digital sensors are exceptional, some of the best I've seen from any lens. The yellowing glass (if not cured) delivers wonderful black and white images. The S-M-CT is also the last version with the gun metal focus ring, something of engineered beauty in its own right, and great to use. Downsides? A bit unfair but as a manual its not the best walk around/take a quick snap lens, and its too long on a crop sensor for my liking.
The better lens?
When the internet first started to fill with lens reviews the S-M-CT was, on balance, rated as the better lens. These early reviews are interesting to me because they tend to come from camera enthusiasts with good personal experience, not overly influenced by the myths and legends now re-cycled on forums/blogs. More recently, the cult status of the early ST version has grown and grown.....driven by the story of a lens "too expensive to produce", and the love affair with bokeh-delicious photos, where wide open sharpness plus smooth bokeh is more highly valued.
Personally, I'd buy the S-M-CT for its exceptional performance...
it is one of the greatest lenses anyone has ever made, period. See this for example
My Favorite Lens . It's the fast fifty I always take on holiday, and optically is better IMO than (say) the FA50/1.4. But as an investment, and for its lesser coatings, I'd buy the early ST if you can find a good one at a reasonable price - under US$175, although I was lucky to find mine mis-listed for under $100 this year. The relative lack of coatings gives photos a special rendering and glow that I happen to like a great deal.
