Question about Pentax *ist D Digital Camera

2 Answers

Program mode I have a question about the program mode. there are 4 choices according to the manual: 1. Normal, 2-High-peed priority, 3-Depth-of-field priority, 4-MTF priority. I know I am going to feel stupid, but what is MTF priority? I wasn't any good at acronyms in the service either.

MTF = Modular Transfer Function. MTF tests is a chart describing the lens performance (sharpness, contrast etc.) throughout the aperture range. All lenses has a "sweet spot", where the best performance is given. But this can vary, not just from lens type to lens type - but also sample to sample (due to manufacturing tolerances). Each sample of modern Pentax lenses (FA, and to my knowledge also DA) are MTF tested - and the aperture which gives the best performance is coded in the MTF chip and read by cameras supporting MTF program. MTF program line simply tries to set this optimum aperture, or coming as close as the light conditions allow.

MTF stands for "Modulation Transfer Function" ... It's a somewhat arcane name for one type of testing methodology used in modern lens analysis. The *ist D's MTF priority program mode sets the "best" aperture to use for a given ISO setting and meter reading based upon lens information encoded in the latest FA series lenses. Earlier series lenses do not include MTF information in their communication with the camera so I suspect it defaults to Normal program mode when non-FA lenses are used.

Nikon D5100 wont flash


Here is a list of things to check:
1. Go into the camera's menus and make sure that the flash is enabled.
2. Check in the menus that the flash is not set in the command mode.
3. You didn't say if your camera was in the auto mode, aperture or shutter priority, etc. If the camera is in shutter priority or manual mode, make sure that the shutter speed is below 1/250th of a second.
4. Make sure that the ISO speed isn't set so high that the camera thinks that flash is not needed.

How does aperture setting affect a photograph?


The aperture is the opening in the lens through which light passes to the image sensor. Changing the aperture setting allows you to control the depth of field of a photograph. When the aperture is opened to a widersetting, (indicated by a lower f-stop number) more light is passed to the imagesensor, creating more shallow depth of field. Closing the aperture (indicatedby a higher f-stop number) allows less light to pass to the image sensor,creating wider depth of field.

NOTE: The aperture setting is one of three primary settings usedto control the overall exposure of a photograph. The other two primary settingsare ISO and shutter speed. Because the three settings work together to produce the overall exposure for a photograph, changingthe aperture setting will require complimentary changes to either the ISO or shutter speed to produce a properly exposed photograph. These changes will bemade automatically by the camera in the Auto, Program, Aperture-priority andShutter-priority modes.

There are two ways tocontrol the aperture setting on the camera:
  • Aperture-priority mode (A) - When shooting in Aperture priority mode (A), you set the aperture value and the camera automatically sets the optimum shutter speed for you.
  • Manual mode (M) - When shooting in Manual mode (M), you control both aperture and shutter speed, which gives you maximum creative control to achieve the exact results you want.

Where do I go to get simple manual focus instructions for my fujifilm s1500? I am trying to work my way throughusing fstop and Iso and shutter speed, but I am not sure which numbers refer to what when I...


The numbers in the left side of the screen is shutterspeed and aperture number.
125 means the shutterspeed is 1/125 sek.
F is the aperturenumber. The higher F number, the smaller aperture opening, the higher depth-of-field.
You can see these number in S, A and M mode.
S is shutter priority: You choose the shutter speed and the camera chooses the correct aperture (within limits)
A is aperture priority: You choose the aperture and the camera chooses the correct aperture (still within limits)
M is manual mode: You have to choose both aperture and shutterspeed. The ruler is an indicator, that tells you when the exposure is correct. The pointer should be in the middle of the ruler.

I do a lot of presentatins an my camera is always letting me dow. The problem is the flash doesn't always work. I put the camera on the 'P' setting. I was given the camera for a Christmas Prtesent and...


"P" is Program mode. The flash won't pop up in this mode unless you tell it to with the manual flash button.
You might be better off starting in Av (Aperture Priority) mode and choosing the depth of field you want via the aperture setting.
The camera will then pick the shutter timing according to the available light.

Choose a smaller number (=larger aperture) for less depth-of field, meaning the background will appear more blurred.

Choose a larger number (=smaller aperture) for more depth-of-field meaning the background will be more in focus.

Aperture


Hello,

On digital cameras you set the camera to Aperture priority and then use your spin dial to set the lowest aperture possible and let the camera set the shutter speed.

In basic terms, the lower the aperture number the shorter depth of the vision field that will be in focus. This is called Depth of Field.

If your camera doesn't have an Aperture priority, usually a capital A on the program dial, you are a bit out of luck... that said, almost all cameras today have this feature. Yours may also be accessed by setting the program dial to Closeup or Portrait mode where the camera will use a short Depth of Field to blur out the background.

Hope that helped of fixed your dilemma.

Canon Powershot S5IS Aperture


Hey Kate
I have owned a Canon Powershot S5 since launch last year and I take a lot of photos with blurred background. I select AV on the dial (Aperture priority) and set aperture to between 2.7 and about 4.0 max, depending on how much depth of field I want and what my subject is.

This setting blurs the background beautifully.. Just remember that an aperture of 2.7 will give you a very shallow depth-of-field, so if focus on face is important, make sure you have face recognition set to ON.

I hope this helps

Aperture priority only in manual mode?


Yes. You pick the apature (the 3000 keeps it aorund the setting you pick) and then it automaticly adjusts the speed for you.

Shutter priority mode?


s I understand it from what I have seen on the Web, the 3000Z can operate in several modes: 1. Fully automatic (camera select both 2. Manual (user sets both aperture and shutter speed). 3. Aperture Priority mode - user sets aperture and camera chooses correct shutter speed to get a good exposure Apparently there is no Shutter Priority mode (user cannot set only the shutter er speed and allow the camera to set the aperature to get a good exposure). This option is available on the Epson 850Z camera and this seems like a silly ommision to make on a "high-end" camera like the 3000Z.
