Win a Pentax Limited Lens: Raffle Now Live!

guillermovilas · 04-21-2007, 09:26 AM

I have a Pentax 40mm f/2.8 and i have to take a step back once every too often because i cannot frame my subject .... i`m not talking about portraits but more like city pics.

So this morning i went and got myself a Sigma 30mm f/1.4.

I`m sure a lot of you are wondering just how good this lens is because on paper it pretty much looks like the perfect lens considering the f/1.4
aperture and it`s low price tag.

I`ll give it a go and post some pics later .

Ciao

Mmmm... Why not just use some HQ zoom? Or is that extra quality really worth changing the lenses every time you take few steps back or forth?

Finn · 04-21-2007, 10:01 AM

I'd like to see a zoom with f/1.4...

aabram · 04-21-2007, 10:45 AM

Me too. But I also wonder what use is 1.4 when you cant reach or fit the subject in the frame...

I think you`ll never see one , f/2.8 is as good as they get and i believe a zoom cannot be as sharp as a fixed focal lens .

They cannot optimize lens quality right through all the range

What do you think ?

Well i like the fact that i have to move to frame the subject , this makes me think a lot more about what i am doing and focusing more on trying to take the right picture , let`s get back to basics.

As for the quality ,a zoom is much more practical but certainly not as sharp.

Well the f/1.4 is very usefull in low light and i shoot a lot in those conditions , it will make a big difference comparing to my DA 40mm f/2.8.

As for fiting the subject well let`s get our legs moving shall we ?
(i very rarely need a long reach , i shoot mostly portraits , city pics and indoors)

Guillermo:

I'm looking forward to your photos and your overall impression of this lens. Having gotten the LBA bug I'm interested in a normal lens for low light use.

Pics and comments coming up real soon , can i ask you a silly question ?

What is the "LBA bug" ?

Jonas B · 04-21-2007, 01:25 PM

I'm looking forward to anything about the Sigma 30/1.4.

And I don't understand why the thread turns into a dusty old prime vs zoom thing. But it keeps the interest on top of course....

Guillermo, is ti possible to get some out of focus streetlamps pictures (or something similar), both in the corners and other places, at the larger aperture openings?

I'm waiting for my copy - no delivery date in sight unfortunately.

regards,

Jeeze, it never fails. Everytime I use a word or phrase I'm not completely sure of I get egg on my face. Based on the usage by many in this forum I assume that it stands for Lens Buying Agenda or something to that effect. I'm sure that you know what happens when we assume, however. (Makes an ASS our of U and ME). I'm also equally sure that some more knowledgeable member of this group will come to your assistance and my rescue.

In case of a "normal prime", the use of feet is advised if you want to get close to a subject and/or fill the frame with it. No one shoots flying herons with a 30mm prime. F1.4 in this case has it's uses indoors and everywhere else where the light is low.

What debate? They all have their proper uses, zooms and primes, F1.4 or F8.

Cheers,

i'm also waiting for some results, especially in low light and wide open.

LBA - coined by Lance B (who sometimes drops by here); Lens buying addicted and Lens Buying Anonymous. In other words, it's a special case of GAS which is the general syndrome widely known among musicians.
LBA has been picked up by Pentax as they actually made some bumper stickers...
