The 15mm Limited controls my mind - club

I think the quality of the starburst is aperture related. Check the exif data on the above shots and compare the F-stop on the ones you like to the F-stop on the ones you dislike. You may find that the best starbursts come from a limited F-stop range, if so, remember that range for future reference.

That makes sense to me however all of the shots I posted were taken at the same F stop (F13). Maybe a different aperature would provide more consistent results?

maybe the darker scene plus the smaller point of bright light gives the better starburst

I think so. Also found that post-processing that lightens the picture will make the starbursts less distinct.

I like your pictures freerider, especially the first and third. I very much want to come in to the city centre and take pictures like these, but it seems like every time I get a chance, the subway and half the streets are closed.

Thank you

I know what you mean. It's amazing how much construction is going on in Toronto. I was fortunate to be staying downtown which made things a lot easier.

Hi all, I've been a fan of this thread for a long time but never had a chance to contribute. I've bought and sold this lens twice before, and each time I regretted it. I eventually picked up another SMC version and finally got the chance to reacquaint myself with it last month in Toronto. Here are a few pics from my trip.

One question I have: I've noticed that sometimes the lens provides a very clean starburst, but other times the starburst is a little sloppy, such as in the first and fourth pictures below. Does anyone know whether this is an issue with my lens or is this normal behavior for the 15mm?

I do not have the lens but your 1 and 4 pictures make it look like the 'not snappy' starburst is actually more than one from light points located within the starburst region of the other.

This lad was just away in a world of his own, I could've just leaned slightly forward and touched his toes... I was that close with my “Mistress" (Pentax-A 15mm F3.5).

The use of a table as support, for this image... but I think I may have well been caught doing this candid by the Red sunglasses.

This is a Kerrowdown WR before Pentax invented WR.

Good observation. That might be the cause.

Geez, if that's your garden, it has a fantastic view.

A good improvisation for a WR solution.

My version of a 15 mm starburst tribute to one of my historical heroes, Ernest Shackleton. Taken just off shore his final resting place on South Georgia Island.
