the theoretical limit of 719 lp/pw in the horizontal axis. It's probably around f/1.6 or some odd number like that.* White balance is available in only one of four pre-select modes.* There is no optical anti-alias filter, so any pattern with detail approaching half the pixel-limited resolution will generate moire patterns; even weave patterns in clothing.In summary, this looks like two different design teams were involved. I still don't really know what it is. a theoretical limit at room temperature of around 9 f-stops given the 4.4 um pixel size (horizontal axis). silk-screened (which makes them totally unreadable in most lighting situations)* No manual focus ring. This is an indication that all the glass surfaces are, indeed, causing a significant loss of contrast ratio.Even so, the camera performs very well in almost all respects.
One for the internals and a separate (and thoroughly incompetent one) for the user controls, form factor, and externals.For my purposes, this is a high-quality hand-held prosumer camera in a kid's toy shell and I cannot really use it for professional work. As the retired chief technology officer for a Fortune 100 company that developed their own digital cine camera, my fundamental interest was in image quality. This 3-CCD, 1440 x 1080i anamorphic 16:9 format camera produces outstanding image quality -- closer to the theoretical limits of performance of 1/4 inch sensors than anything in its price range.The complex optics (zoom with a telecentric focal length converter ahead of the prism assembly) should be expected to reduce the available contrast ratio because it has so many glass surfaces. Here are the problems:* The body is a big, mostly-empty box with mold lines showing, in a medium gray color, with labels for connectors and controls being molded in vs.
This mystifies me: Putting a Trabant or Yugo body around a Mercedes engine. This is like a kiddie toy wrapped around a very high quality lens + sensor package. THIS MAKES IT IMPOSSIBLE TO USE THIS CAMERA FOR FOLLOW-FOCUS SHOTS, and will therefore completely disqualify it for use by anyone that must have this capability.* No manual iris ring, either. But, if you need a shoulder-mounted ENG camera for outdoor action photography, this might be just the ticket.
This takes away an important variable in depth of field control.* Iris full-open is not marked. Color saturation falls off sharply with non-optimum exposure. Again, buttons must be used with the menu to set depth of field.* Gain cannot be set higher than 0 dB when the iris is closed below full-open. Without the sophisticated equipment to measure MTF (modulation transfer function) at home, I measured effective resolution instead, which was 576 lp/pw vs.
Manual focus can be attained, but only by running the focus motor through pushbuttons. Perhaps they are adequate for ENG work and action footage, but nowhere near adequate for professional photography. Panchromatic dynamic range excedes 6 stops (I cannot reliably measure more than that) vs. It measured out at ASA 100 with 0 dB of gain.It has two XLR inputs.So far, it warrants about four stars.Now for the bad part: User features are poor.
This Camera is Ginormous (Gigantic+enormous) Considerably larger than the old VHS style camcorders. Great I thought I solved the problem of pixellated video in HD. I decided to try a prosumer type video camera, and this one was the least expensive HD available at the time. I love the video quality, but it is too big to carry to Disney World or a soccer game or pretty much anywhere that you are not set up to shoot video. The quality of the video was astounding. OK, I am not a professional videographer, but I know what looks good on a nice television or screen.
What happens is that you get a kind of ghosting in the video, so the High Def picture I was shooting for looked very pixellated and low quality. However, there was one small problem. I tried the smaller HD camcorders (Canon HF 10, and Sony HDR-SR11), and they have excellent video quality if you do not move the camera. I could get the same quality during moving shots that I could get with the static shots using the hand-helds. The flash memory is excellent, and I have not noticed a huge difference in the picture quality of this camera utilizing flash memory and my current Sony HDR-FX7 utilizing tape. I mean don't follow your kids around the yard or try to video a bird in flight or pretty much anything moving.
Once it arrived at my house I used it to video several different scenes that gave me difficulty with the hand-helds.
After checking out online reviews by Digital Content Producer and VideoMaker, I decided to go with the Panasonic camcorder. While the HD video quality is sharper with the Sony, the Panasonic AVCHD still looks good without the blocky artifacts you sometimes see when recording motion in HDV compression. 2009 two models available.
The Sony records HDV compression to Mini-dv tapes V.S. The biggest reason for me going with the HMC70 was that it had XLR inputs (use external mic instead of camera's mic), while the Sony only had mini-jack for mic input. the Panasonic recording in AVCHD (13Mbps highest option) to SDHC memory cards.
Decided to look for an inexpensive shoulder mounted high definition camcorder: there are currently, as Feb. So don't think that for 2 grand you are buying a camcorder that can compare to the more expensive models. I also wanted to use memory cards instead of tapes.Check out online reviews for yourself before buying either camcorder.
The Sony HVR-HD1000 and the Pansonic AG-HMC70 (HMC70P, HMC70PJ are NTSC models, PAL models use different numbers). The shoulder models both use "professional" versions of consumer handheld cameras.
no focus ring(infact there is no ring on this camera)3. no zoom ring2. no zoom control jack(so you cant use this camera with tripod remote)4.nedd lots of light(understandable ,becuase u are paying under 2 grand and ccds are only 1/4 inch)overall if you are in transition phase from dv to hd ,and dont want to spend lots of money then this camera is number one choice,other wisebuy hmc150 i am one of those few people who own both hmc70 and hmc150.while my hmc150 is top notch product,i cant criticize my hmc70 if i look at the fact that it cost 1/3 of what hmc150 did to me.hmc70 is consumer camera fitted into big body,but.this consumer camera will put lots of other professional camera to shame.if u are looking for hd quality under two grand look no further.i bought this camera when it was on sale 3 weeks ago.price went up since then.pros: great picture(under good light though),sound is good even with in built mic,very reasonably priced for 3ccd ,2 cold shoe,volume indicator ,decent view finder,great professional look for this price,and above all no more tape(sdhc recording is really a revolution in professional video business)1.this camera has 3ccd(1/4) which you cant find in other canera at this price range(i always thought panasonic give more value to your money than sony,jvc let alone canon -canon dont have technology to make ccd so it use pana ccds thats why it is always expensive)2.these 3ccd produce very good and almost clean picture even when u record at full 13mb/sec settings(you need good amount of light though- buy one on camera light , 100 watt at least).3.recording on sdhc card has changed equations forever,u will not look back to mini dv sony or jvc cameras.dumping whole movie in to your computer is similar to dumping photos from still camera.4.avchd recording can be edited on corel video studio 12,adobe premier element 7,pinnacle 12,power director 7( i would suggest COREl because it does not render avchd after u finish editing,than mean u save time and image keep its quality,although u need to turn on smart proxy for avchd editing,but then u can even edit this on single or dual core,u dont need quad core computer).5.if your customer need regular dvd,u can still use this camera and then before u do editing,transcode this avchd to mpeg 2 using any of the above softwares.( trick here is that u should transcode avchd to mpeg with at least 9 mb/sec variable bit rate setting,so in case u need to put 2 hour on single layer dvd ,u will get better quality,but if u have faster computer u can always edit in native avchd then output final file into mpeg2 )5. best sdhc card is transcend,but you buy pana,kingston,sandisk,never buy adata brand)6.buy one extra battery(sad thing is No other generic battery is available so prepare to spend 169 more for decent pana battery)please note this camera has few cons (because pana sont want to give you everything for this price)what those thing missing1.
