Sanyo PLV-Z3000 vs. Panasonic PT-AE3000
Two Hot 1080p Projectors Compared

The AE3000's Lens Memory Feature

Leaving aside frame interpolation, the one other major feature that might cause you to opt for the Panasonic AE3000 over the Sanyo Z3000 is its Lens Memory. However, this is only relevant if you are interested in setting up a 2.35:1 super wide Cinemascope screen instead of the standard 16:9 screen. If you aren't, you can skip this section.

As discussed in the AE3000 review, Lens Memory lets you automatically set the zoom lens to a wide angle setting to fill a 2.35 screen, so that you can view a 2.35 format film in full frame without any black bars. Then when you switch to a 16:9 source such as HDTV or a 1.78 film, you can press a button, and the projector will automatically zoom the lens to a position where the 16:9 image fills your screen vertically. And, unless the projector is positioned exactly at a height equal to the middle of the screen, a vertical compensation adjustment is required to get the image to center vertically on the screen. The AE3000 automatically makes this adjustment as well. Essentially, this eliminates the expense of a separate anamorphic lens.

You can accomplish the same thing on the Z3000, but the zoom lens is manual. So for each change of material between 2.35 films and regular 16:9 material, you must manually adjust the lens to accommodate it. And, if necessary, you must then manually adjust the vertical height of the image as well. This can be a tedious procedure if you do it very often.

So in a nutshell, the situation is this: if you don't want to install a 2.35 format screen, the AE3000's Lens Memory is an irrelevant feature for you. If you want to install a 2.35 screen and want also to use an anamorphic lens, you can use it on either the AE3000 or the Z3000, so again the Lens Memory feature is irrelevant. However, if you want to get into 2.35 format and don't want to spend $4,000 to $7,000 on an anamorphic lens, the AE3000 gives you a very practical and easy to use alternative.


The Panasonic AE3000 and the Sanyo Z3000 are fascinating products that have interesting features that no other home theater projectors have. They both deliver superb image quality. Overall, the AE3000 has a small edge in brightness, contrast, and features. Its frame interpolation system is more powerful than that on the Z3000, but it lacks the Z3000's 5:5 pulldown system that users who object to frame interpolation techniques might want to opt for in its place. The AE3000 has been, and will probably continue to be, the more expensive of the two products by a few hundred dollars on the street, and it includes either a one-year or perhaps two-year warranty in some instances. The Z3000 is less expensive, and carries an attractive three-year warranty with the basic selling price.

We've still got a lot to say, and I could keep writing for hours about the intriguing quirks and capabilities of the Z3000 and AE3000. But this article is getting too long. If you are looking for an aggressively priced high performance home theater projector, we hope that this is enough of a comparison and overview to lead you to a good decision as to which of these two innovative 1080p projectors might be the right one for you.

The Panasonic powered zoom (and associated format switch feature) is enormously useful even if the screen one has is not 2.35:1. Different formats will require zooming to take best advantage of any screen. (It's only with a 4:3 screen, where the limiting factor is always width, that the feature might become irrelevant -- and even then it would depend on the projector's characteristics as it switches between formats.)

I have a 16:9 screen (which works as a good compromise for all movie formats and fits well on the wall of a standard room) and have to zoom in and out (and adjust height) every time I switch between classics and 2.35:1 movies. The black bars (top and bottom for 2.35:1 or left and right for classics) have not bothered me, esp. with the kind of deep black levels one gets today. However, the powered zoom is crucial, since my projector is ceiling mounted -- it would be completely impractical to adjust manually every time.

The otherwise excellent and very helpful reviews posted here tend to understress the usefulness (I would say, the indispensability!) of a powered zoom -- at least for users who have ceiling-mounted projectors and watch media in different formats.

No mention of the Sanyo's dust cleaning feature?

A very interresting comparisson. I like the Panny more, but I'll wait for the Epson 6500 UB review and hope it will have that same Frame Interpolation like the Panny. Also I wanted to thank you for the Felston Audio Delay that was mentioned somewhere. It works extremely good. I had a movie from the internet with a delay of one whole second, and it was no problem for the Felson. You guy's are exstremely helpfull.

Thank you very much.

Hey ProjectorCentral. Can you please post your optimal settings for both projectors?

120 Hz sounds perfect for the upcoming nVidia shutterglasses for stereoscopic viewing, since they require that refresh rate. Would the combination work, are the LCD panels truly fast enough to eliminate left eye/right eye ghosting? If so, I'm sold.
James Fletcher Posted Dec 24, 2008 12:24 PM PST
The 1:2.35 zoom is not really an anamorphic substitute is it? Surely the point of anamorphic is to allow all the pixels on the LCD to be displayed on the screen, thus maximizing the resolution and light delivery. As described by you, zooming the central band of pixels out wider does not offer this advantage, but just makes the zooming process more convenient. Nice review though!
kevinp Posted Dec 28, 2008 1:09 AM PST
Surley the point of anamorphic is to display the image in a 1:2.35 Format. Panasonics solution may not be a perfect. But it will do a resonable job without the need for an expensive anamorphic lens. A cheap anamorphic lens may not give you a better picture.

What about the noise of these 2 products ? Sanyo claims 19dB and Panasonic 25dB, has someone ever compared them ?
Phil Lewis Posted Feb 8, 2009 9:01 PM PST
I am still watching with a Sanyo Z4. I have had it for over 3 years and it has performed flawlessly. After over 1500 hours on the bulb, I replaced it as the picture had lost brightness. This is just to demonstrate the reliability for the Sanyo.

As to watching 2.35 as opposed to 1.78 and all the ratios in-between, I haven't discovered any problems. On my 10ft wall-screen (DIY paint yourself screens) the 1.78 movies fill the screen and the 2.35 movies fill the screen horizontally. As was previously mentioned, in a darkened room (movie theatre style) the blank horizontal bars on top and bottom are not really noticed. No refocusing or picture resizing or position shifting is necessary.

When I finally upgrade, I'm not sure which projector I will buy, but, at this point, I'm more intrigued by the smooth motion for the Sanyo or frame creation for the Panasonic. Each sounds very interesting and the Panasonic seems to be a little bit better according to the review. The judder problem is quite apparent when viewing panned scenes.

As an aside, I've really become accustomed to auto-lens door on my Sanyo. It has worked perfectly and does a good job at keeping dust off the lens.

Does anyone have any idea about input lag of these projectors? My PJ use is roughly 50/50 movies/gaming, so this is a huge factor for me.

I'd like to know AE3000/Z3000 input lag when frame interpolation is turned off, and when it´s used in max setting (mode 2 / high).

Can anyone help me out?

I have used panasonic pt ae 700 earlier (first bulb blew at 300 hrs.) which had dust problems sent it for cleaning to company but within few days a blue patch started appearing on bottom right corner which was increasing by the day. ultimetly sold off the projector ( bulb was on 700 hrs.) & bought Sanyo Z-5 which i am using since 2 yrs. bulb used for 1400 hrs. There is no dust problem at all. So according to my opinion Sanyo projectors are more reliable than Panasonic particularly concerning dust problems.
Alec Posted Mar 4, 2009 5:15 PM PST
I guess performance is by company is somewhat relative to model and even each unit. I have had a Sanyo projector for 3 years (plv-60) and have had a number or problems with it. It got lots of dust accumulation inside, though the filters were cleaned regularly. Then it developed a problem where it began displaying alternating red bars next to dark-light transitions. I sent it to Sanyo and they claimed it was out of warranty, even though I had the original receipt showing it was only two years old. They were supposed to have fixed it (not under warranty, at my cost - I had removed the cover to blow out the dust, and foolishly told them so), but image problems were still present, and now about 9 months later, the original problem is back. I have also read of problems with the PLV-70 blowing bulbs a lot due to heat problems. The moral of the story is that different models by the same brand may vary quite a lot.

I've had PLV-Z4 and Z5 for two years, no problems. In a store I compared the noise of the AE3000 and Z3000, and the difference is clear. 6 dB is as such, a huge difference in sound pressure, but of course the basic level is already very low in both units and you can never be sure of the manufacturer's measurements. However, Z3000 is clearly the quieter one.

I agree with the insightful remarks (not the reviewer's, who is usually impeccable, particularly as tutor, as I think we all gratefully know) about the aspect-ratio accommodation issues, and the proper way to deal with them. I've used the Pano AE2000, which lacks the memory (and another feature I'll get to), but has the remoted zoom-focus. I have a motorized 130" diagonal screen. The zoom-focus was (and remained) hella fun, especially for focusing (what I thought were pixels from a few inches from the screen. Turned out I was viewing tiny dimples on the screen surface- test pattern more reliable!)and for fine-tuning filling the screen. Most useful is the caliper-like V-H positioning wheels, so unlike the stick-slip joysticks on my other Panos). My ceiling mount could also benefit from such machine-like positioning; it seriously pisses me off.

But- back to the equivalent of aperture-plate filing and teasers and tormentors- what you want to to is not zoom or focus for 'Scope, but reposition the image upward and motor-up the screen to frame the bottom edge. The H-V positioner doesn't have to be motorized to do this, nor does the lens. What needs to happen is that the IMAGE raster be painted at the top of the 16X9 imager, rather than by default centered, and the screen needs to be rolled up to mask the blank unused portion of the imager, however good the contrast. Problems do occur when subtitles are maliciously formatted below the frame, but I say just learn a foreign language and chill.

This trick could be implemented on my trusty AE100 in firmware; wish they had. Also wish they'd done a smoother job with H-V adjust. One more gripe- color temp varies slightly corner-to-corner, making B%W films and credits agony for lunatics like anyone reading this far. Also: Oano AE100 has heartbreaking chromatic aberration- terrible, inexcusable, although admittedly unnoticeable except to me. AE2000 lens was Canon L-quality perfect.
doog Posted Apr 28, 2009 11:12 AM PST
Regarding noise, once again I can speak only of my experience with the AE2000 predecessor, but it was really, truly inaudible, in any mode except ramp-down. I had it on a table at ear-level while fussing with other stuff. Really excellent in that respect, as was (still is) the AE100, though the 100 (ceiling) is barely audible in my woodsy very quiet room if no one is breathing, especially the oversize pooch. Too bad movie sound has a dynamic range around 90-130dB SPL. But it's technically sweet.

I seem to have too much time- one more thing about Mr. Powell's bakeoff between the Panasonic and the Sanyo projectors. Not only does it seem self-contradictory internally, balancing each of the shortcoming of the Sanyo by re-iterating the largely useless (he points out, since it's inconsistent with frame interpolation))%:% thing.

What's more confusing his unequivocably ecstatic review of the Panasonic (considered alone, at intro) contrasts markedly with his grudging, dutiful concesion that with a laboratory of instrumentation it could produce an image in some respects similar, if dimer, thasn the Panasonic. Plus motorized remoted memorized this and thast, test patterns galore, nifty split-screen- why are these two projectors considered rivals? I say this with such frustrated heat because I just ordered the Sanyo, to check it out, on the assumption that I'll eventually return it and pony up for the Panasonic. The Pano product cycle sems pretty snappy, so maybe there'll be an AE3000.1. I hope it doesn't have a white case- another Powell fundamental world-voew error. Other wise, great work!

I have a Panny AE700E - It was raved about in reviews when it was new - 3000 hours quoted bulb life, 2000 luniens, no screen door, fab picture, verry little VB, only 900 notes when i got it and for the first 1000 hours all this was true so ture i recommended Panny PJs to all my friends - this bigger pic for under a grand! But it was too good to be true ......... From all the internet research I have done (many hours) the marketing should have said "Great picture (true), amazing price for the performance(true), When we tweak the firmware, lamp PSU and bulb spec you will get 2000 hours out of the gobe if your lucky (otherwise you will only get 300 hours) but by the time you get to 2000 hours you will have replaced the projector at least twice! - Panasonic - replace the PJ not the bulb! To cut a long story short the things overheat. In the early months this caused bulbs to fail at sub 300 hours... this was corrected but the cooling round the LCD panels is poor and the panels and optics are organic and degrade with heat VERY quickly.... add to this that the optical block / out duffuser / LCD pannel assembly must be replaced as a whole costing more than the PJ did to begin with! After just 1200 hours my PJ's blue LCD panel is so burnt that i now don't use it. The forums are full of AE700 owners who have the same problems and have been lied to and cheated by Panasonic. £950 is cheap for the specs but a LOT for just 1200 hours. This product is not fit for purpose and I have heard similar reports on other "reasonably priced" Panny PJs

I am an engineer and I took the unit appart in the end and it is clear to see why it fails....

My advice - just Google "panasonic projector problems" then Google "Sanyo projector problems"...

then BUY THE SANYO! I wish I had!
Rich Tervo Posted Sep 22, 2009 5:57 PM PST
Been using a Sanyo PLV-Z3 now since they came out, still going strong... replaced the bulb once and thats with watching TV shows, sports and movies on it constantly. I had friends who opted for the Panny at the time, they all pooped out after a couple of years due to problems mentioned in posts here. Sanyo definitely has the better build quality. The 3 year warranty doesn't seem to be needed. Probably why they offer it!
