Re: Wide angle for K-X?

2010-01-03 Thread Carlos R
Besides the excellent 16-45 that some people suggested, there is the FA 
20-35. Small, AF and high IQ too, though you would have to look for a 
second hand one.


The Voigtländer 58mm 1.4 seems an excellent choice for an 85mm 
equivalent, but I think it will be hard to focus it accurately using the 
comparatively small K-x viewfinder, as you come from an MX which has an 
enormous viewfinder compared to APS-C DSLRs. Every time I compare my two 
MX to the *ist DS and K10D, I am astonished at the difference. But in 
that case you can buy a Pentax O-ME53 magnifying eyecup.

What I have in mind is the classic 35/85 two lens kit.

35 full-frame equivalent would be wide enough for most of my
purposes. Good cheap 24/2 or 2.8 would be first choice if there
was one. 21 Limited definitely appeals, but nothing wider unless
it is a zoom.

I thought of a 10-20 or 12-24 zoom, but I don't think I'd need
the wider end much and those lenses tend to be fairly heavy
 expensive.

On the longer side, 75 mm equivalent is the minimum, and
I'd prefer a bit longer. Voigtlander 58/1.4 is my first thought.

I can afford 21 Limited and 50/1.4, giving me two autofocus
Pentax lenses. Those look like a good match and comments
on them are all positive. 50 is not quite as long as I'd like,
but you can't have everything.

Voigtlander 58/1.4 would be preferable on the long end,
but it is more money, not autofocus and perhaps harder
to match. Might not work well with 21, too big a gap
between.

I thought perhaps the 58 and Sigma 24/1.8 to give me
two fast lenses, but the Sigma i's fairly heavy and no-one
here is praising it. I'm no longer considering that.

The advice to use the 16-45 was a surprise. That is a
pretty flexible lens. Going down to 24 mm equivalent
may not be essential, but it is something I'd use.

The obvious 2nd lens to go with it would be 70/2.4
Limited. That would be a bit beyond what I want to
spend, but a very flexible kit. Hmmm

WTB: 77mm 1.8 limited

2009-12-19 Thread Carlos R

I have been saving for the last few months in order to buy a portrait
lens, and finally I have made my mind and thought that the 77 limited
would be my best bet. But with the recent price hikes, I am afraid I
can't afford buying it new, so if one of you is thinking about selling 
this lens in excellent condition, I am ready to listen to offers.


Thanks for your attention,

Carlos

Thanks for your answer. Prices around here (EU) are cheaper, in spite of 
the recent price hikes. I can get a new one for 650 or 700 euros if I 
shop around, but I'm looking for a less expensive one, that's why I'm

Larry Colen escribió:



Because the manual focus on it feels horrible. It's lumpy getting 
stiff with every rotation of the auto focus drive screw, then loose on 
the other half. This also sort of makes it tough to focus accurately if 
the focus point is where it doesn't want to turn.


If the lens were bad optically, I'd just return it.  It's too much to 
ask that all lenses feel like a supertak 50, but this one is beyond 
reasonable.






I have the Sigma EX 28 mm. 1.8 macro. I know it isn't the same lens, but 
 it is closely related, and the manual focus feeling doesn't have 
anything to do with your experiences with the EX 24 mm. If you disengage 
 autofocus BOTH on the camera and lens, manual focusing with my lens 
isn't stiff at all, it is very fluid and nearly as good as with 
traditional manual focus lenses. So I'd say that your 24 lens is 
defective and you should exchange it.


Like I wrote in a previous message some days ago, you must be sure you 
disengage AF by using both the camera AF/MF switch and also by pushing 
the focusing ring on the lens towards the camera body, as, 
unfortunately, these Sigma lenses can't deactivate the AF motor in the 
camera body only by using the lens clutch, like genuine Pentax FA* 
lenses do (FA* 24 mm. 2.0, FA* 300 mm. 4.5, FA* 80-200 mm. 2.8 and some 
others).

Re: Focusing the sigma 20/1.8

2009-12-10 Thread Carlos R
You need to set both the camera and the lens to MF, as if you don't you 
will end damaging the in-camera AF motor. If you only use the lens 
clutch, it isn't like on Pentax FA* lenses, on which you only need to 
push backwards the focusing ring to disengage AF.

Larry Colen escribió:

Does anyone else have the 20/1.8?

Optically it seems like a sweet piece of glass. Unfortunately while I 
needed it last weekend, it didn't show up until Monday and I haven't had 
a lot of time to play with it.


The first thing that I noticed was that in manual focus, focusing  it 
felt like it was turning a motor.


It also turns out that if the lens is in manual focus, and the camera is 
in auto focus, autofocus still works, it's just that the focus ring 
won't turn when the camera focuses.


Looking on the mount, when I manually focus, the drive gear for the 
autofocus will turn.


The big problem is that this makes the lens unpleasant to manually 
focus, though it works fine, it feels bad. Is this the way it's supposed 
to work? Or do I have a bad copy of the lens?

There is another Sigma lens, one which I would buy in an instant if I
find a good sample - AF 24/2.8 Macro II. I had this one borrowed from
a friend. Wonderful optic. Read somewhere that it was either
co-developed or co-produced or co-something with Leica. As sharp as A
24/2.8, slightly more prone to flare, good bokeh and AF. Just as small
and light (52 mm filter diameter). On digital it would make close to
ideal street shooter's autofocus lens of angle of view of 36 mm with
DOF of 24 mm lens.




I have one of those and your words describe it very accurately. It is a 
gem of a lens, pity it doesn't have the improved anti reflection 
coatings of the EX series lenses. I had a Pentax FA* 24 mm. 2.0 which I 
liked a lot on film, less on the digital bodies and finally sold it. The 
FA* has many virtues: it is fast, well built, focuses fast and it is 
very contrasty. On the other hand, it shows red-green CA, easily 
correctable in post processing though.


I also have a Sigma EX 28 mm. 1.8 which I like a lot, except for its 
weight and bulk.

You can always buy a cheap PCI card to add some USB 2.0 ports to your

Well, it looks like its time to do something about my 8 year old MDG

Its been acting up again the last few weeks, not booting. It does
after a number of reboots. I get a boot fail, system halted, or a full
DOS screen with all my memory numbers and a few other things, and at
the bottom i get press f12 to boot form network or f1 to enter set up.
I enter set up, scroll over to exit and it boots.

Its an old machine, slow and USB 1.1 to boot, but its calibrated well
for my Epson 2400 prints, so i'm leaning on fixing it one more time.
Going in Saturday for a look see. Hopefully adding a new HD and
mapping my stuff off the old one will work. The HD was upgraded 3
years ago and never really worked well after. Many boot problems, but
it would work, eventually.



The symptoms you describe are compatible with an exhausted battery. 
Every motherboard has a small lithium battery to keep the PC clock 
running and also the BIOS settings which are kept in a CMOS memory. That 
battery (usually a CR2032) has the size and shape of a coin and it is 
cheap and easy to change. Around here, they are easily found in hardware 
shops or even supermarkets. They last about 8 or 10 years, so it seems 
that the one in your PC is already flat. I would buy one of those and 
try to revive the ocmputer.
