Panasonic PT-AX100 vs. Sanyo PLV-Z5

Jack Liu(dupin67)翻译

又是十月。 像往年一样,丰收的月亮升起,秋色覆盖了大地,杨基队在决赛中败北:),家庭影院业再次见证一场LCD巨头:Panasonic和Sanyo的全新对决。

本年度的对决主角是Panasonic PT�AX100USanyo PLV-Z5,同属于原始1280X720分辨率的LCD家庭影院投影机,售价在2000美元以内。我不知道谁能够赢得职棒大连盟,但是对于家庭影院投影机,我们不乏预言。

在AX100和Z5之间找一个绝对的赢家是不可能的。两者都是杰出的投影机,性能远超上代机型。两台机都有些性能胜过对方。我们对两台机在所有项目上都给予了五星,不是因为它们是完美的投影机,而是因为它们都代表着这个价位上投影机的最高成就:提供大量功能和极好的图像质量。两机中哪台适合你,完全取决于你的观看类型。一句话,如果你打算或者必须在一定的环境光线下观看,则AX100U是更好的选择,而对于全黑的影院观看来说PLV-Z5是更好的选择。两台机都有各自的评测。(见Panasonic AX-100U评测Sanyo PLV-Z5评测。)

印象和观测报告

Panasonic在AX100U上面付出了巨大努力,相比其前一款机型PT-AE900,尤其在流明输出潜力上有了极大的提高。AX100U的额定输出为2000流明,与此相比,AE900为1100流明。AX100设计为既可以在黑暗的室内影院环境中使用,又可以在中等的环境光下使用,取决于用户的实际情况。由于很多人没有能力或者不希望在一个黑暗的环境中观赏电影和(或)体育及其他HDTV节目,因此,AX100的大范围可变光强度输出,给这些人提供了大多数投影机所不能提供的观赏灵活性。在这一点上,相对去年的AE900,AX100是一个极大的进步。

与之对比,Sanyo的新款PLV-Z5并未在一开始表现出是一个相对于去年秋天发布的PLV-Z4的巨大进步。Sanyo提供的指标显示出一定的改进。 以对比度而言,Z5为10000:1,与之相比Z4为7000:1。 流明输出增加了10%,从Z4的1000流明增加到Z5的1100流明。不幸的是,亮度和对比度指标往往对消费者行为有着超出应有程度的影响。所以,让我 们关注一些真正的,没有出现在官方指标里的问题...

视频分辨率 两款投影机都拥有1280X720的物理点阵的,或者说原始分辨率。然而,两者解析细节的能力是不同的。相对于Z5,AX100U能够清晰地解析比标准 DVD视频清晰度更多的垂直线和水平线。用通俗的话来说,这意味这AX100U有能力播放出些许更多的精确定义的图像细节,例如,织物的纹理或者草坪上草 的叶片。
优势型号:AX100U

象素 AX100U拥有Panasonic特有的"SmoothScreen 技术",该技术可以消除可见象素结构,即使从离屏幕几英寸远的地方观察。相比之下,当从足够近的地方观察Z5的图像,可以看到明显的象素结构。在LCD投 影机而言,由于象素间距的减少,这种现象已经不像以前一样显著了,但是问题仍然存在。

到底影响有多大?如果您准备从近距离观看一个非常大的图像,比如从十英尺的距离观看120英寸对角线图像,那么您将在Z5的图像上看见一些在AX100U 上面所不能看见的微弱的象素结构。在白色文本,滚动演员表以及字幕上最为明显,并且通常在视频图像中不易发现。如果退后到十三英尺的观看距离,由于从这个 距离看清如此小的细节是困难的,因此Z5的图像中的象素结构几乎完全消失。就我个人而言,Z5的象素结构完全不造成任何困扰,但对于那些对象素结构敏感且 打算坐得离屏幕很近得人而言,AX100U能够更好地消除这个瑕疵。

优势型号:AX100U

隔行转逐行 AX100U的隔行转逐行性能杰出,即使与价格比之贵许多的投影机想比,仍然不遑多让。Z5的隔行转逐行接近于杰出。在用隔行转逐行测试模式进行的AB测试中,AX100显示出微弱的优势。然而,虽然测试模式揭示出AX100相对占优,但在典型的观看条件下,这并不能转化为任何显而易见的区别。当观察标准分辨率的电影和视频片断时,想要发现一个隔行转逐行瑕疵,在AX100U上不存在,而在Z5上存在,是及其勉强的。

微弱优势型号:AX100U

数码噪声 对于数码投影机而言,一个普遍的瑕疵是噪声。噪声表现为在视频图像中某些物体的微弱的不稳定性,带给整个图像一种微弱的颗粒感。噪声的存在,使得你即使不 能指出某个的特定的瑕疵,也会减少图像的整体锐度。在这个价格段内我们曾进评测过的所有投影机中,Z4有着最低的噪声级别。在与AX100U进行AB对比 的时候,Z5的低噪声成为一个显著的优点。

优势型号:PLV-Z5

对比度 官方公布的Z5对比度为10000:1,AX100U为6000:1。在AB对比中,Z5的对比度确实要高些。黑色电平几乎相同,但Z5呈现出更大的色调 范围和更加明亮的高光。这给予了Z5的图像稍好一些的景深,或者说三维立体感。差距并不是巨大的,然而对任何人而言,进行并排演示时,确实是看得出来的。

优势型号:PLV-Z5

图像锐度 在本次实投观察结果中,一个最为有趣得现象是,Z5的图像看上去更加锐利,尽管实际上AX100U能够呈现出色的细节。这怎么可能呢?对我们而言,看起来 这是一个前面所讨论的所有因素的综合结果。虽然AX100U的图像从任何角度而言都不会是非常高噪声的,但其噪声水平仍然较Z5为高。这一点使得 AX100U在视频解像度上的潜在优势被抵消了。另外,Z5的更高对比度也对一个更为锐利的图像起到了作用。最后,我们仍然对AX100U上的象素结构消 除技术持有怀疑,虽然就投影机本身来说是个好东东,但对锐度可能有细微的负面影响。Panasonic声称该技术对锐度没有影响,并且事实上AX100U 比拥有相同的"SmoothScreen技术"的AE900,明显地更加锐利。然而我们仍然持保留态度。不管由于什么原因,实际上Z5呈现出的图像较之 AX100U是要锐利那么一点。(顺便提下,在我们的测试中,Z5的锐度控制设置为最低值-7,并且另一个锐度控制选项--瞬时增强,设置为次低值 L1。)

优势型号:PLV-Z5

因此,选择完全取决于你想用投影机去做什么...

Panasonic PT-AX100U相对于Sanyo PLV-Z5的最大优势在于它高出很多的流明输出潜力。对一个大型party,你可以将其设至高达1400流明以上,从而获取一个中等环境光线下的明亮的 图像。对于一个黑暗的观赏空间,你可以将其设置为"Vivid Cinema"模式得到一个超过800流明的输出,从而成功地投满一个非常大的幕布,比如,大于等于150英寸。在环境光线下,Z5相对于AX100U的 对比度优势没有用了。如果你打算主要在环境光线中观看,Ax100U是明显的更好选择。

另一方面,如果你的目标是在黑暗影院环境中获取最佳的图像质量,Sanyo PLV-Z5是更好的选择。如果我们不需要AX100U的流明输出能力,我们绝对会选择PLV-Z5,因为它有着更高的对比度,更低的数码噪声,以及更加 锐利的图像。另一个吸引人的地方是其更低的价格和三年保修--AX100U有着业界标准的一年保修。

不管你选谁,它们都代表着Panasonic和Sanyo的漫长的宽屏幕LCD产品线上的杰出家庭影院投影机。两者都是让人印象深刻的机型,我们热切地推荐你根据观看需求,选择其中之一。 (全文完)

I've had the Z5 for about a year and a half now. I honestly dont think I could be any happier. I've got my PS3 going HDMI to the Z5 and 5.1 audio through the PS3's optical out and my little theater setup blows people away.

Actually since visiting my theater, FOUR of my friends have either gotten projector setups or are in the process - my Z5 has made me quite the trendsetter.

One thing should be noted. When the PS3 is sending a 1080p signal to a 720p unit (like the Z5), it actually scales the signal down to 480p - or so it says in the menu when you look at the current signal being recieved while a blu-ray is playing. However, the picture is visibly richer AND sharper to the naked eye despite the "scale down". I found this strange but im not making a stink since the picture really does look better than standard DVD.

I picked up a bargain screen - $200 from circuit city - 100" diagonal - and playing games like Call of Duty 4, Assassin's Creed or any other well rendered game is extremely immersive. Just a blast.

I would HIGHLY recommend this projector to anyone.... ANYONE. If youre the kind that doesnt see much difference between 720 and 1080 signals, this would be your cheaper alternative for a great, no, EXCELLENT theater/gaming experience..

BUY IT.

Well, thought I would give some quick feedback on my experiences with the Sanyo now that I owned it for a while.

The short answer, I'm very pleased and impressed with the Sanyo. It's doing everything I hoped for and more. The picture really jumps off the screen, and I went with an Elite Screen 92" 16x9 screen, a bit pricey but after spending that cash on a projector why skimp on the screen.

Right now I have a HTPC as well as DirecTV HD powering the projector. HTPC has a DVI to HDMI cable, 25' long, and the picture is perfect. The DirecTV HD has a HDMI to HDMI cable, same distance, works great. I also connected a cheapo DVD player with Component out, works great.

The Sanyo has plenty connectors on the back, which eliminates the need for a switcher box, which is great.

Audio is being sent via optical from DirecTV HD to the HTPC, I have an Audigy 4 platinum 7.1 sound card, which works awesome by the way, that also has optical in/out ports.

I purchased Creative S750 speaker system, 7.1 with 700watts of power, http://www.newegg.com/Product/Product.aspx?Item=N82E16836116142 , and it upconverts 5.1 and 6.1 to 7.1, awesome deal.

So, I would recommend the Sanyo highly, if, and a big IF, you theater can be perfect dark with very little ambient light. The colors, contrast, clarity are all top notch.

Before getting Panasonic AX100 it would be wise to read this: http://www.avsforum.com/avs-vb/showthread.php?p=9345730&&#post9345730

"Just learned, that Bway is total scam, stay away completely."

Just a head's up for anyone contemplating doing business online (especially a big ticket item) with a company they haven't any history with, check the company out at the Better Business Bureau online at: http://search.bbb.org/searchform.aspx

For example, here's what they said about the above-mentioned dealer: "Complaints to the Bureau indicate that this firm uses high pressures sales tactics after consumers place their orders. After ordering merchandise consumers report receiving a phone call from the firm’s customer representatives attempting to sell additional items. Representatives allegedly try to persuade consumers to buy the U.S. warranty, as well as accessories like cables, peripherals, and software, or lead consumers to believe the product will not work if additional merchandise is not purchased. In some cases, if the consumers declined, an email was sent advising them to cancel their orders because the item was on back-order despite being listed as available on the firm’s website. Consumers also reported unauthorized charges on their invoices. When trying to dispute such charges, consumers report difficulty talking to management, claiming they are verbally abused by the company’s staff."

If it hasn't been posted here yet...Panasonic HAS a new rebate offer if that Block Buster thing is not for you.

You have your choice of rebates for the PT-AX100-U if purchased from ANY US source as long as it is a new model and not a "B" rated one (which I think is refurbished to them).

Anyway, the link below is to Panasonic.com to their rebate choices for this model. $400.00 CASH off or you can take the $200 with the $300.00 Blockbuster thingy which I think is a waste of time. I'd rather have the $200 in my hot little pocket to put toward my screen!

I am considering buying it through VisualApex.com for $1899.00 (then minus the rebate) but they also give out an additional 1 year GE warranty worth a bit over $100.00. I don't know if that is really worth it; however, free is free. Maybe I should scour the net for better prices first?

When I first found the rebate on visualapex.com, I was skeptical because I had not heard of the $400 cash back yet. I called Panasonic Rebate division at their toll free number on the claim form (PDF online ... see link below) and they were not aware of the rebate offer yet; however, they did say that they are a 3rd party company and don't always get notice of the warrantys right away). I then called Panasonic direct and he walked me through their site to find the actual rebate there. It is valid but only from Feb1 till the 28th purchases! Go Gettum Fellers!

I went with the Sanyo, the final deciding points were clarity and the Sanyo's better performance in dark rooms. The Panny is good if you have more ambient light to deal with, but I don't.

I jumped over to NewEgg, www.newegg.com, and they are still the best ever. Anyway, I picked up a 25' DVI to HDMI (male) adapter. My projector is at the back of the room, electronics at front.

My PC is running WinXP SP2 and a GeForce 7800 GT Vid Card. What impressed me is that Windows recognized the PLV-Z5, by name nonetheless, and automatically set screen resolution to 1280x720P. Absolutely perfect.

How many times does this stuff actually work out of the box, like never, but sometimes you just get lucky.

"I too, am contemplating between the two. I read a great article on the Panasonic:

http://www.projectorcentral.com/panasonic_ax100.htm

And one on the Sanyo:

http://www.projectorcentral.com/sanyo_plv-z5.htm

And a shootout between the two:

http://www.projectorcentral.com/ax100u_plv-z5.htm

After doing all this, I'm still perplexed. The main difference between the two deals with the Lumens. The Panasonic is brighter, thus can be used in rooms with more ambient light. The Sanyo, however, is better in dark rooms, like those dedicated to a home theater.

Another big different is the 1080p/24fps support of the Panasonic. 1080P/24 is the standard for HD-DVD and Blu-Ray. Those that don't support this framerate do a conversion which could result in stuttering scenes, especially during panning sequences.

THe Sanyo does not state is supports that combination, thus I'm really perplexed. My Theater is a dedicated theater, no windows, pitch black. Everything points to getting the Sanyo, however, that 1080P/24 compatibility keeps me from pulling the trigger.

Price is not a big difference, I actually found the Panasonic for less (1350.00):

http://www.bwayphoto.com/product.asp?id=psptax100e&pid=similar

Sanyo is offering a $200 Mail in Rebate for purchases up to 1/31/07.

Arrgghhhhhhh !!!!!!!

Evan Powell where are you, help !!!!!!!"

Check out projectorreviews.com. As far 1080p (whatever fps) resolution, it does not matter. The z5 and ax100u are both 720p native. 1080p images will be downconverted to 720p. It's how well the image resolution is scaled down. The only advantage of the ax100u is maximum brigthness. The z5 are actually measured for 1400 lumens output. And it is brighter than the panny at economy mode. Other things for your consideration are, automatic lens cover, sharpness and shadow detail (10,000:1 contrast), cost and warranty. Hope this help

FYI. I just got off the phone with BestPriceCameras and they confirmed "no bulb". Not the friendliest people either...

By Blueper

This is great info on this board. Thanks! I'm leaning toward the PT-AX100U, but I've noticed most of the sites that list it don't even specify whether it's "U" or "E". They just say PT-AX100.

BestPriceCameras has it for $1319 now. Does that mean they put a 25 hour bulb in there?

Thanks again.

Off topic, but on the topic we're drifting in to, I just narrowly avoided being caught by a similar (yes, I will use the word) SCAM by BestPriceCameras. The are advertising the Infocus IN72 for the amazing price of $389. Totally by accident, I found out that the units are shipped with a bulb that will only last 25 hours. Since the replacement 3000 hour bulb is $400, it turns into a crappy deal indeed.

Here is the URL for the IN72 at BestPriceCameras.

http://www.bestpricecameras.com/prodetails.asp?prodid=568807

Although it may be different content by the time you look, it mentions nothing about the bulb issue. The bulb life also seems to be missing from the specs...probably just an oversight.

I actually got both (PT-AX100U and PLV-Z5) and after tyring them both (return policy is 5 hours of less on lamp) my personal opinion is that the PANASONIC is the winner (overall). The Sanyo seemed sharper in a very dark room; however, one pays a price for that on the pixilation and it is not good for rooms with moderate ambient lighting.

I got my PANASONIC PT-AX100U for $1899 (I am not counting the $200 Rebate). However, I am willing to return it to get the one from Broadway if Broadway offere you the US version (PT-AX100U) for $1539 (yor total upfront cost for projector) NOT INCLUDING the $200 rebate that PANASONIC offers. It so, the end cost would be a lot less...some $1339 and that would be a savings of $360.00 ($1899-200 (rebate)=$1699) - ($1539-$200 (rebate)=$1339).

Please let me know soonest!

I had ordered the PTAX100 last night at the $1350 price from Broadway unaware of it being the Europe version. I have to go against the the claim of a "scam" here however. Broadway called me this morning (before putting my order thru) to let me know this was indeed a Europe version and did I still want to order it. (No scam intent there). It DOES come with a bulb, and is the exact same projector only all the menus etc are in Japanese. : ) They offered me a great deal on the US version on the phone for $1539. Which is about $400 cheaper than any place else. So I went with it.

This will be my third projector ( I started with the very first InFocus ScreenPLay 4800 3 years ago. And it still works great! Just ready for the new resolution etc.

Am very anxious to try out this new Panny.

Just learned, that Bway is total scam, stay away completely. A few other posters gave the tip, thank goodness, whew, didn't fall down that hole. So just stay away from them !!!!!!

I'm starting to lean towards the Panasonic and away from the Sanyo. Both appear to be great projectors, both from good companies and although the Sanyo might be better for me in my theater, looking down the road a bit, I know better units will continue to be released, and if I upgrade, I will push my current projector to side duty, and the Panasonic just seems to give me much more flexibility than the Sanyo at that point.

So, in line with your thoughts, think about the next unit you buy, and then what are you going to do with your older one, I think you'll agree with that logic.

I didn't know Panasonic had a Mail In Rebate, do you have a link for that?

Posted Jan 4, 2007 9:04:22 AM

By Coach

FYI...I called the folks at Broadway Photos. They indicated that the $1350 Projector you found at Broadway Photo is the PT-AX100E vs. the PT-AX100U. It is the same projector; however the "E" is made for Europe and it DOES NOT come with a LAMP and the 1-yr warranty is good only overseas; therefore, if something went wrong with the projector, one would have to send it overseas for repair/replacement. Once one adds the lamp, the projector's total price comes to $1549. Additionally, the PT-AX100E does not carry the current PANASONIC $200 rebate as the PT-AX100U.

In terms of the 1080p/24, I am not too concern about that, since I do not foresee playing full HD video on either projectors (PT-AX100U or PLV-Z5). For that, I would be investing on a full HD projector; however, those are still in the $3899-5000 range. And considering the trade off in picture quality and availability of the full HD media, at this time I do not believe it would be cost cost effective to jump on the 1080p ride--just yet.

Thoughts?

I found the Sanyo PLV-Z5 for $1,350 and the Panasonic PT-AX100U for $1,699. The Panasonic is $349 more than the Sanyo. I was wondering if someone has had some experience with both projectors and is willing to share their opinion as to wether the panasonic is worth the extra $349; considering the Projector Central Shoot-out review from October 2006, on both of these projectors.

Thank you!
