Can the camera be used without the grip at all?

What does it look like without?

I ask thinking about my old Spotmatic/K1000 and the way it looked / felt in the hand without a grip at all.

Understanding Aperture: Manual vs Auto

Just for personal preference I really wish it did have a use, when I took a photography class back in the dark ages (25+ years ago) I used an old Spotmatic F.

Using that I got used to the idea that my Right hand controlled the shutter, adjusting the shutter speed and when to take the picture
My left hand controlled the lens, the focus point and the depth of field.

I understood that when I adjusted one I would have to adjust the other to maintain the proper exposure, i.e. if I knew I wanted more depth of field I would adjust with my left hand, and at the same time I would have to slow the shutter down with my right.
There might be times when I would have to live with a slightly off exposure picture due to needing more/less aperture/shutter speed to get the intended result that I would have to adjust in post

Using my K-r (I know its old) which only has one adjustment dial, full manual mode is pretty difficult. its not intuitive to adjust one (i.e. aperture) and then click another button to switch to adjust the other (shutter)

I know the higher end and newer cameras have two adjustment dials but I still prefer the idea of one hand controls the lens and one the shutter, it just makes more sense in my mind.

But then again that is personal preference.

and now they have the color I wanted when I got my K-r almost a year ago.

Silver, not because its some sort of ultra special 'Limited' edition but because I really like the look.

Oh well.

Who else are waiting for a firmware update for K-r to fix the FF problem

First off I understand how you feel, this is a pain in the backside.
Am I happy that there are unresolved issues with my K-r?

But how exactly is the marketing and manufacturing production of the lens you mention related to the software/firmware work on the camera bodies?
Its quite possible that the marketing, manufacturing, distribution, and other planning work related to the launch of the lens was already 95% done before the quake and that last 5% probably had nothing to do with the camera firmware division.

I know for a while there there were rolling blackouts in parts of Japan due to the power-grid issues and they still might be having them for all I know.
Now I don't know if the location where the firmware is developed was in those parts of Japan, but Its kind of hard to work on the software issues without power if it is.

And with over 12,000 confirmed dead, and many more expected, how do you know that the people working on the firmware are not dealing with deaths of loved ones? Or dealing with loved ones who are are among the many more displaced and homeless?

The fact that there is a significant bug with the K-r auto focus in low light is a major pain to many, but there are workarounds that may work until they release an update.
Use LiveView, which uses a different method do determine focus.
Or manually focus, ignoring the focus confirmation indicators, and use your eyes like we used to with manual focus cameras.

Right now as an ameture hack who takes pictures for fun, I have only been bitten by this once, and that was before I joined here and read what it was.
Looking back at it, if I knew about the problem then, I would have skipped the auto focus and just went manual.

I am going to try and patiently wait for the fix, and in an attempt to keep the issue a priority for them, respectfully remind them periodically that the issue affects me on occasion.

How long will I wait before I start getting 'Mad' about it?
I don't know, but I know it took a little more than a month for the people affected by Katrina to get back to a 'normal' routine.

According to the email I got back from Promaster the only p-ttl flash they have that will work with the recent pentax cameras is the 7500edf

From the email I got from Promaster, mid Feb
So the flash combo you are looking at will work but it will not be p-ttl

And there is no guarantee that the 7500edf will work with the Kr

When I mentioned updating the firmware, I had been thinking about the flashes firmware.

I dont know if Vivitar flashes have upgradeable firmware or not.

I know that the Metz flashes allow you to update the flashes firmware yourself, and I have heard of people sending in their flashes to Promaster for a firmware update.

Try and contact Vivitar to see if they have any information on your DF-383 and the Kr, you may be able to send it in to them and have them update it for you.

I dont have any first hand experiance with the AA battery adapter I haven't gotten it yet so I may be off here, and I know I said it before, but have you tried setting the battery type to something other than Auto?

From my understanding Lithium-Ion batteries are easily damaged by draining them all the way so many manufacturers will put in 'Safety nets' in their products that prevent the product from draining the battery all the way.

I have heard many people complain about how their new lith-ion cordless drill will not give them any warning when the battery is about to die, unlike the older Ni-cad batteries.
You could tell when the Ni-cad's were running low because the drill starts to loose power, with the Lith-ion they run strong until the cut off then they just stop.

I don't know if pentax has this sort of 'Safety net' built into their camera's or not, but if the camera is confused and thinks that you have put in a set of Lith-ion batteries when you are using the Ni-cad/Ni-MH, the lower voltage they provide will make it think the batteries are dead and try and "save you from yourself" and prevent you from damaging the batteries.

Looking at the Lith-ion pack that came with my Kr I see its a 7.4v battery, which is a big jump up from the max 4.8-5v your brand new fresh Ni-MH AA batteries will provide, which is probably why they provide the settings in the menu anyway.

Its possible that its a bug in the 'Auto' battery mode where it tries to 'save' the battery before it tries to determine the battery type.

Its also possible, (and actually more likely now that I think about it) that the camera's 'boot' sequence requires a certain amount of current draw to start and if the batteries are unable to provide the juice fast enough you will get the low battery warning.

Alkaline, Ni-cads, and Lith-ion batteries generally provide a faster current draw than Ni-MH batteries, but there are some Ni-MH batteries out there that provide a faster current draw than others.
Which might explain Hypocorism's experience where some rechargeable work and some don't

There is a battery 'type' setting in the menus.

You need to make sure that you have it set for the Ni-MH batteries.

This may have changed sense the last time I checked but the Ni-MH batteries usually have a lower peak voltage than alkalines ( 1.2 vs 1.5 )

If the camera is expecting 6v like it would from alkalines and it gets 4.8v from the Ni-MH it would think that the batteries are not fully charged.

vivitar flash with kr overexposing

Quick question what model is the flash?

Its quite possible if its an older flash its incomparable with modern DSLR's.

I recently picked up a Kr, I picked it up because of the features and to go with my existing Pentax film SLR gear, including a Promaster 5500 flash.

When I put the flash on my Kr I was surprised at how poorly they were playing together.
The Promaster is a TTL flash and it worked really well with my ZX-10 but on the Kr it was blasting away at full power unless I manually set it to 1/16 power.

So off to the web I went, and learned that most of the older film flashes do not work properly with digital cameras, in fact many of them can damage the circuitry of the DSLR.

When the flash is triggered there is a short voltage spike, most of the DSLR's are rated for a max of 5-6 volts (If I remember correctly) and many of the older flashes have a voltage spike much higher than this, I saw a couple that were in the 200 volt range.

You may want to go to the Vivitar site and check to see if your flash is even safe to use on your Kr.

If it is, they may be able to upgrade the firmware to work with the newer Pentax's I don't know.

I on the other hand am out of luck with my Promaster and need to start saving up for a new flash.

Any idea on what kind of filter this is? (Soviet made)

Thanks for the confirmation and the info.

Just to let you know these filters actually go on the front of the lens, they are big 77mm monsters.

Looking at the lens there are some threads at the rear but the optics of the lens doesn't leave much room to mount anything there.
Plus the case the lens came in has a dedicated space for these front filters but no spot for any smaller filters so I think I can say it doesn't need the rear mounted ones.

I have a Soviet made 500mm mirror lens that came with four filters, three of them are easy to figure out.

One is amber, one is green, and one is gray.

The fourth is the one I am not 100% sure of, its clear so my guess is that its a UV haze filter but sometimes its better to ask.

There does not seem to be a brand name on the lens, but it does have what I guess is a brand mark/symbol. A lower case 'c', inside a triangle, inside a circle.

The only marks on the filter are:

*CIO 77x0,75

So am I correct in thinking that its a UV haze filter, or is it something else?
Possibly just a piece of glass to help protect the lens?

Or a super secret filter used to view invisible inks on KGB documents?:lol:
It was made during the 'Cold War' (1979):hmm: <--- :lol:

My two Pentax film camera's

A ZX-10 and a Spotmatic F

Picked up the Spotmatic used for a high school photography class, didn't really realize how nice a camera and lens it is until much later.

The ZX-10 was picked up new back in college.
I remember how much it hurt my wallet to get it, but it almost hurts more now looking at prices for one now on ebay ($20-40 if your lucky)

Included are the lenses I have two Sigma lenses 28-80mm and 70-210mm and a Soviet made 500mm.
