28mm Sigma or Pentax?

I need (want ) a 28mm lens and I have a choice of getting a SIGMA PKA FIT 28mm F2.8 Wide, with macro this month. Or saving my pennies for another month and getting a Pentax SMC-A 28mm f2.8 Wide Lens.

I wonder if any of you who have experience of either of these lenses would give me an idea of which would be best please.

Many thanks,

Charlotte

My experience is that the Pentax lenses are generally superior in many ways. They fit better, operate more smoothly and usually offer better performance.

One undersetimated benefit is that the colour balance of the images is very consistent from lens to lens. This will not be the case where makes of lens are mixed.

The Sigma doesn't have a brilliant reputation (the 24mm version DOES though - look out for that one!) I have had the Pentax 28mm, it was OK but f2.8 wasn't really that good.

I would swerve both of these options and get the Pentax K 28mm f3.5, if you must have that focal length. However... I much prefer the Sigma 24mm Superwide II for it's wider focal length on APSC, and excellent wide open performance.

I will second that idea, if you can find a Sigma 24mm Superwide II it is a fantastic lens. They seem to getting a bit scarce and a bit expensive though; I paid 30 quid for mine, but have recently seen them going for 3 times that.

The cheapest I can find a Sigma 24mm Superwide II is 120. where as the 28mm sigma I can get for 30. and the Pentax 60.

In your opinion is the superwide worth double the Pentax ?

I'd really like the 10-20 - but that's way out of my price range.

I really appreciate your input,

Kind regards

You really have this LBA thing bad, eh?

A Superwide II will probably come up for under 100.00 if you're patient, and I do think that's still worthwhile for what is a nice useful lens. In the meantime why not splurge on the Pentax and see how things work out. The great thing about buying old lenses is you can always change your mind and sell them, often for more than you paid if you shop around

Don't buy on ebay using unrealistic "Buy It Now" prices. The 24mm
Sigma should be 65 - 70 max.

Another vote for the 28mm Vivitar close focus. A great lens, rparmar has written extensively about them. PK versions currently about 25 on ebay, PKA versions about 50. The ones with a serial number starting with 22 or 28 are thought to be the better ones.

Charlotte, I bought a Pentax-M 28mm f3.5 from ebay in mint condition for 28. Although this is the 'manual only' version of the lens, it is still a great lens and by all accounts is optically one of the best 28mm's. If you don't mind the 'manual only' and can find one I would highly recommend it.

I appear to have developed a craving for lenses.

I can't comment on the specific lenses you have in mind, but in my experience of owning both Sigma and Pentax lenses there's no real difference between them in overall performance.


On specific comparisons however you'll find Sigma will be better or Pemtax will be better depending on the lenses you are comparing.

Best advice I can offer is to try and search out some pics taken with either lenses, compare, and then weigh up any other factors, such as price

Thank you for your help everyone. Lots of food for thought - will have to have a look around for images from the various lenses.

The 28mm will have to wait a couple of months though because - I really don't know how it happened but I seem to have bought a Sigma 50mm Macro.

Kind regards

Well I was patient, made an offer and have received today a sigma 24mm superwide II.

first impressions is that it is a really sharp lens and 'tis wasted on me, but look forward to 'playing' with it tomorrow.

Does this LBA thingy wear off after a while or am I going to become divorced and bankrupt after a couple of years?

Thanks for all your help,

I always find it's best to buy the other half something every time you purchase a lens. New ironing board, hoover, washing machine, hostess trolly have all worked in the past. How can I tell I hear you ask .. just the look of joy on my wifes face said it all.

I suppose in your case it would have to be a new lawnmower, electric screwdriver, hosepipe or similar

Enjoy the lens, I only sold mine when I found an AF version.
