A Tak? Maybe under $50.... 3.5/35mm SMC...

I have lenses that can starburst like that (my tak bayonet 135 f2.5). I'm looking for something that starbursts in fine lines like I've seen in some pictures.

a quick perusal through my flickr and the bursts that stand out are the 21 Limited, the 40 Limited, the Sigma 28 EX DG, and the Sigma 70 EX DG...

the Sigma 28 is for sale, but not that cheap.....

And yes, I love my K 55/f1.8 also - isn't it really a Tak with a different mount?
Never thought of this, and you might be right as many Taks' formulas were used on early Ks... I have the Smc tak 55/1.8 - never done a comparison between these two folks,,, adding it to the list of to-do's

PS - thank you

Would be an interesting comparison considering the Tak uses a radioactive element.

I have a Takumar 55/1.8 and a K 55/2 and render very similarly....

That's not surprising considering I'm pretty sure they're identical formulas. The only difference is some of the Taks have radioactive doping.

Pentax 645Z + 645 A 75 mm f/2.8 @ f/16. Ice floes on the Saint Lawrence in winter.

They call this the "winter blues" ... lol!

I think both of Pepperberry's Taks have thorium elements. Now the 55/1.8 tak vs K - there you'll get different formulas due to different glass... Looking at the database both the tak and the K are 6/5 designs however.

IIRC the SMC Tak 55 and K55 are identical save for the mount. I have both and can attest they render nearly identically. That is, very nicely indeed

currently only have two Takumars - the 24/3.5 and the 55/1.8; neither of which have been reported as radioactive...

I had a 35/2 that was quite yellowed and I used a UV light to clear it.... I've since sold the lens (but not because of the radioactivity)...

EDIT:

supposedly, the Mamiya 58/1.7 is radioactive, but I've only seen it reported on one site....

I have this lens, and yes, have also read so. It also yellows... Corection, I have the Mamiya 55/1.8, and I believe it is also radioactive and it yellows.

From our database on the Tak 55/1.8 = From the 1965 version, at least one of the glass elements is made from radioactive glass which yellows over time.

Read more at: SMC/S-M-C/Super-/Auto-/Takumar 55mm F1.8 Reviews - M42 Screwmount Normal Primes - Pentax Lens Reviews & Lens Database



SO I reckon it depends on which version of the tak 55/1.8 you own...

it does - I have the late Super-Takumar 55/1.8 - number 7 on the list of 9....
