Pentax Optio 430 Images Quality And Specification Review

The three mega-pixel Optio 330 was first declared back on 29th May 2001, later, in Sept Pentax declared the Optio 430, a four mega-pixel update to the 330. The two cameras are basically similar apart from the extra picture dimension the 430. Body style, management structure and choices are all exactly the same. Because of this, and because I’ve already analyzed the Optio 330 much of this evaluation is based on the Optio 330 evaluation. If you’ve formerly study that evaluation you may wish to miss to the picture assessments and picture quality evaluation.

The Optio 430 actions just 92 x 62 x 31 mm (3.6 x 2.4 x 1.2 in) and that makes it only just larger than Kyocera’s small S4. Completely packed (including battery power & CF card) the 430 is in at a portable 240 g (8.5 oz). The Optio 430 has a metal case, four mega-pixel indicator, three times opstical zoom capability, exclusive Lithium-Ion rechargable battery power and Lightweight Display Type I port.

Pentax Optio 430 Body And Design

The Optio 430 is only a little larger than Kyocera’s small Finecam S4 and just 45 g bulkier fully packed. It’s dressed in an all steel case, the only nasty parts are the LCD cover, control buttons and section gates. The rather traditional design is convenient to carry, portable and clear and understandable. Just like the Finecam S3 the Optio 430’s lens expands an inches from the body once you is operated up, I found the lens expansion and zoom capability motor to be rather loud (compared to others).

LCD Observe / Viewfinder

The Optio 430’s 1.6″ (an uncommon size) LCD monitor is shiny and simple enough to see even outside, it’s secured by a nasty window which should prevent it from damage if carried in a wallet, although there’s no anti-reflective covering. The Optio’s viewfinder is the pretty standard ‘optical tunnel’ kind with no parallax modification lines (although there are AF segment indicators), uncommonly for an ultra-compact the Optio’s viewfinder has a dioptre modification.

Battery / Lightweight Display Compartments

In the base of the Optio 430 you’ll discover battery power section. The small Lithium-Ion battery power has a ranked outcome of 3.7 V, 900 mAh (3.3 Wh), this rests it somewhere between battery power used in Sony’s DSC-P5 and that used in The canon eos PowerShot S40. The battery power is billed out of you in the provided battery charger. On the right side of you (from the back) is the small Lightweight Display section door, it’s made of nasty and doesn’t depend particularly well. Behind this we get a CF Type I port, cards are placed with the thumbs lip at the rear which does makes it much easier to eliminate the card later.

Pentax Optio 430 Features

JPEG/RAW Picture Dimension & Quality

The Optio 430 provides three different outcome solutions (2240 x 1680, 1120 x 840, 640 x 480) along with three JPEG pressure configurations ( 6:1, 8:1, 16:1). The Optio 430 does not have an uncompressed TIFF or RAW method.

Image Handling Adjustments

The Optio 430 allows you to management three different image processing parameters: Sharpness, Vividness and Comparison. Each of these can be set individually and in any mixture. You instantly memorizes these configurations after energy off.

ISO (Sensitivity) Adjustment

ISO equivalence on a digicam is the ability to increase the understanding of the CCD to allow for quicker shutter rates of speed and/or better efficiency in low mild. The way this works in a digicam is by “turning up the volume” on the CCD’s indication amps, nothing is without its price however and doing so also increases any disturbance that may be present and often impacts color vividness.

The Optio 430 has two ISO understanding options of ISO 100 and ISO 200. There is also Automatic ISO which will be different the understanding instantly based on available mild. It’s unfortunate Pentax did not include an ISO 400 option. The plants below are taken from three spot roles on our conventional color areas taken at ISO 100 and 200.

These areas don’t tell the whole tale, if you pay attention to the center greyish spot you can see some minor mottling at ISO 100, more noticeable mottling and disturbance can be found in every day pictures around places of details (see this observe plants on the first page). It seems to be as though the Optio 440 is using a relatively powerful disturbance decrease criteria.

White Balance

The Optio 430 has an excellent set of white-colored stability options such as guide predetermined white-colored stability which we really would not anticipate finding on an ultra-compact digicam. As you can see from the outcomes below the Automatic white-colored stability worked well best in daylight. The pre-programmed white-colored stability configurations were excellent, indeed the incandescent and neon configurations are probably the best I’ve seen on any customer digicam. Manual predetermined white-colored stability also worked well very well.

Low Light Focus

This analyze actions the lowest quantity of mild under which electronic camera can still concentrate. The concentrate focus on is our lens distortions analyze graph (shown here on the right), electronic camera is placed exactly 2 m (6.6 ft) away. Light levels are progressively decreased until electronic camera can no longer concentrate. This is performed at both extensive position and telephoto zoom capability roles (as more mild gets to the concentrating techniques with a bigger aperture). This analyze focus on is the the best possible type of topic for most “contrast detect” AF techniques (as it has a straight line at its center), you should consider the outcomes below the best you could anticipate to obtain.

Flash Performance

The Optio 430’s inner display has a specified range of 0.14 – 3.7 m (0.5 – 12 ft) at extensive position and 0.4 – 2.0 m (1.3 – 6.6 ft) at telephoto. In our assessments it continuously created underexposed or highly red throw pictures. This is a indication of either an incorrect white-colored stability (which should really be closed for display pictures in low light) and / or inadequate display visibility metering.

Barrel and Pincushion Distortion

The Optio 430 lens gun barrel distortions at complete extensive position was calculated at 1.2%, this is towards the great end of what we’d anticipate. The information is better at complete telephoto, no considerable pincushion distortions.

Purple Fringing (Chromatic Aberrations)

Overall the 430 did as well as its three mega-pixel sibling the 330. Violet fringing was almost invisible even in very excessive pictures. About the only thing worth referring to was a lot of flourishing radiating from overextended places into picture details.

Overall Image High quality / Specific Issues

Generally discussing the Optio 430’s picture was excellent if you’re going to use downsampled pictures (for web publishing / email) and substandard if you create at large dimensions or are like me and analyze all your pictures at least 100% zoom capability. Colour stability was excellent, as was mid to high-tone black and white, but things got muddier in the dark areas (see below). The 430’s inner disturbance decrease system can also lead to some unusual relics, extremely sleek places outlined with loud details. To my eye the 430 doesn’t achieve lot from its 4 mega-pixel indicator.

Noise Artifacts

Another feature which became noticeable pretty early on in my examining are what I can only explain as disturbance relics. These styles (artifacts) of disturbance appear around places of details on an otherwise sleek area. What I can only believe is that electronic camera has a built-in disturbance decrease criteria (a bit like a “smart blur”) which is cleaning up disturbance from sleek places but avoiding when it gets to places of details. The best example of this can be seen around the a few moments numbers on this observe face plants below.
