Sony EX system only offer one thing over the other systems and its more flexibility and control. Otherwise its output is compareable to the likes of HDR-SR12. DOF adapters don`t require machining tools, its pretty easy to make if you know what you are doing. Adding a prism reduces amount of light, while post processing doesn`t. Buying a letus beats the purpose, since we are looking for cheap alternative, for the price of letus adapter, one can get a second hand 5d mk2, unless you are using it with EX or HVR series. Not the dpreview comparison again. Its 2 different cameras for 2 different segments, pleasecan we for once go apples against apples. Also remember, bigger the zoom, more compromises need to happen. One of the reasons most of the cameras come with 3x zoom. Its quite simple to correct or flip the image, its just the fact that adding another lens/prism/element means light loss doesn`t matter what the companies say. Cheers | |

| DOF adapters don`t require machining tools, its pretty easy to make if you know what you are doing. Adding a prism reduces amount of light, while post processing doesn`t. These are the tubes you need to get machined: Daniel's GG-Holders for 35mm DOF Adapters Actually same result can be had with 5D mk2 and that too with just the cost of the DOF adapter. Sony EX system only offer one thing over the other systems and its more flexibility and control. Otherwise its output is compareable to the likes of HDR-SR12. Quote When it comes to critical focus this is when things get difficult. With a shallow DOF focus is hyper critical and every cameras bar one has a sub par LCD for focusing. Only the EX1 and EX3 have usable LCD, the other cameras really all need external monitors. Philip Bloom 35mm adaptors Try getting follow focus on a 5dmk2 without an external monitor! The GH1 has autofocus in video mode: awesome! Face detection: even more awesome! Buying a letus beats the purpose, since we are looking for cheap alternative, for the price of letus adapter, one can get a second hand 5d mk2, unless you are using it with EX or HVR series. SonyEX1 rig 10k 5dmk2 rig 5000k GH1 1500k with more capabilities. Not the dpreview comparison again. Its 2 different cameras for 2 different segments, pleasecan we for once go apples against apples. The LX3 only leads in low light capabilities. The tz7/zs3 has acceptable low light results. Also remember, bigger the zoom, more compromises need to happen. One of the reasons most of the cameras come with 3x zoom. 24-300 mm sharp all the way. Its quite simple to correct or flip the image, its just the fact that adding another lens/prism/element means light loss doesn`t matter what the companies say. I agree. |

Quote: Also for that matter, Paraffin wax with microscopic slides as focusing screen, it will surely work but will stop fair bit of light. Making something remotely acceptable to canon focusing screen isn`t that easy, compared to focusing screen making a lens element is a kids play and you can check YouTube to see actual lens manufacturing done at canon.

Sony EX1 - 3.5-inch* type colour LCD monitor, approx. 921000 effective pixels, 640 (H) x 3 (RGB) x 480 (V), 16:9, hybrid type Canon 5Dmk2 - 3.0 " TFT LCD, 920,000 pixels, Automatic 3 level brightness adjustment plus 7 manual levels, 170 ° viewing angle, Dual anti-reflection ('Clear View') And there is a reason why external LCD`s are used, an external lcd can be the size of 5" to 50" plasma. And it’s easier to focus and compose with bigger lcd than a 3.5" lcd. To be honest, i cannot remember last time i saw someone using built in lcd to focus and compose. Quote:
I am not saying GH1 is a bad camera, quite opposite its very good but you are comparing contrast based AF to cam based and comparing full frame to 2x crop factor. By doing this you lost DOF advantage and fast AF performance. Quote:

RAW f2.0-2.8 ZS3 NO RAW f3.3-6.3 Difference here is similar to PRIME vs KIT LENS; just compare your average 50mm f1.8 to a kit 18-200mm. LX3 also has arguably more manual controls. Sharpness is not the only factor when choosing a zoom and it’s a fact that big zoom means COMPROMISES in other areas otherwise zooms are rarely compact, classic example Nikon 80-400mm vs Nikon 200-400mm or for the fact Nikon 1200-1700mm.

2. dude there a many nikon lenses for which canon has no alternate and vice-versa. 3. Why do I need this DOF adapter. We have not found a need for this. We take vide. I convert video to DVD (using Ulead) and watch. Ideally I would love to be able to stuff my AVCHD SD card into the PS3 and watch but I dont know if the PS3 can recognise a AVCHD video. Quote:
the f/4 is sharper than the f/2.8 when both lenses are tested at f/4? Quote:

Team-BHP Support ![]() ![]() | I always used to wonder if canon would make an APS-C cam which would allow me to take 10-20 minute shots with manageable noise. Well from the review 7D seems to be the answer. A guy on dpreview took 30 minute shot of his roomba in pitch dark, and the results are impressive! Guess when vitamin M is available, 7D will be a good upgrade. |

| Quote When whole point of having video mode on a DSLR is to use its low light capabilities and being artistic, you are telling me you will rely on autofocus and that too which is Contrast Based. Correction. The whole point of getting video mode on a dslr is to get easy and inexpensive and effective film look, ie shallow DOF. The GH1 beats all the other cameras because of its shortened flange to sensor distance (no mirror ) which allow a multitude of lenses to be used. Currently expensive lenses worth USD15000+ carried as spare on film locations are being mounted on GH1’s, serving as B cameras, test/set up cameras and general backup, replacing Arriflex equipment costing tens of thousands of dollars more. The 5dmak2 is crippled by having a problematic 30fps frame rate, making it difficult to interleave with normal footage. Before this becomes too technical for people who have so far been interested but may drop out , please know that the GH1 is viable kit for people who want that beautiful DOF, and welcome the additional goodies that Panasonic developed for its consumer Camcorders: IS, autofocus (you need to hire a focus puller with pro rigs!), tilt LCD, face detection, manual shutter and aperture AND 50/50 fps. Take that small cam to a Cirque de Soleil performance, shoot at 50fps and crank it down to a slowmo framerate on your desktop and I guarantee you’ll be a fan for life! All this at a consumer level cost of entry! We can post on the dpreview thread if you want, because it would be beating a dead horse exercise here. All the relevant ground has already been covered at the link I provided. The LX3 has controls that can’t be used given the small sensor size, even though it’s marginally bigger than that of a normal PandS. You pay more for unused bells and whistles. Thanks for a stimulating discussion! |

FYI DX and EF-S sales should be way more than pro equipment sales. Infact pro equipment is mostly given free for advertising at huge prestigeous events. If not for these lower consumer luring cameras there would be no money for all the R&D and spending on pro equipment. Infact pro equipment enables people to enter into either system who want to take those professional looking photos that these pro takes and their entry point into either system is DX and EF-S. These are the most important divsions for both Nikon and Canon. A question for you. Is there any adapter that aloows full AF and matrix metering on Canon bodies for Nikon lenses. I guess TTL metering is there but I am not sure of AF. If no such perfect adapter exists, No one in their right minds will ever sell all their Nikon bodies and manually focus all their G and D lenses on Canon bodies.

| Quote 3. Why do I need this DOF adapter. We have not found a need for this. We take vide. I convert video to DVD (using Ulead) and watch. Ideally I would love to be able to stuff my AVCHD SD card into the PS3 and watch but I dont know if the PS3 can recognise a AVCHD video. Quote A The PlayStation 3 and many other Blu-ray players can play AVCHD video directly from memory cards. Simply plug a high-speed SDHC card reader into a PS3 USB port and insert the card directly from your camcorder. The card will show onscreen as a video source, which you can select, play and control with the PS3 remote. Some stand-alone Blu-ray players also have USB ports or SD card slots that will accept the cards directly. PS3 can handle memory cards | StarTribune.com You can also burn blu-ray and play on ps3s. Quote Not that the TZ7 or ZS3 are bad camera but I wonder if a 24-300 or 28-560 lens will be as fast or have as little distortion as a 24-60 or 28-100 lens respectively. You cant have 15x or 20x zoom without distortion at both ends of the zoom range. The other factor will be speed (in effect low light - indoor light capability) longer zoom ranges mean more glass elements. Each glass element added means loss of some light. I read recently that all lenses performance are acceptable in normal light. A recent comparison of kit lenses and HG zooms with the same range performed equally, even though the HGs were higher specced (faster stops). Primes and HG/SHG lenses really shine in low light situations. How much of our shots are low light? Even rock concerts are well lit nowadays! ![]() |

Don`t confuse it with Depth of Focus. DOf adpater is used to get similar DOF like you see on professional productions, like movies in cinemas. Idea is you mount a 35mm lens on a tube and project the image on a focusing screen. You put this tube in front of your camcorder and zoom till you just see the complete focusing screen. This give you 35mm look. Don`t think just using this adapter and playing back on a big screen will give you cinema look, you will need to shoot at 24p since that is what is used in cinemas. You can shoot higher and bring it to 24p in post processing easy enough. I am not sure about PS3 and memory card scenario. But i beleive you can access it over a network and still watch. In my case i only and only play Wii. Have you tried Vegas yet? i beleive it solves quite few issues over ulead but is a bit slow in rendering. Quote:
f2.8 lenses provide sweet spot for DOF. Quote:

And everyone that jumped from film is either shooting 2k+ or staying with film. Since none of the DSLR`s/1080p cameras(yep sony ex series) are good enough for them. To be honest here in australia, Sony EX series have been dumped and almost all studios are moving onwards to SI. Red is an option but too many issues with the equipment at this stage. Even recent digital solution from Arri is good enough for them. Quote:
Its good to read Dpreview`s reviews on cameras but me going into the forum, sorry but that`s not going to happen. Dpreview forum is a group where users buy 1dxxx, Dx and Axxx series and argue over 400% magnification of jpeg`s than anything else. Not to mention the users who buy and stock gear but never shoot anything. Quote:

This is how tests are manipulated or a mistake is made during testing. For example leave one variable and all the other constants don`t matter at all. Its like Ken Rockwell comparing Leica 24mm f2.8 vs Canon 16-35mm f2.8 and Nikon 24-70mm f2.8, even tough most of the things are constant, he`s comparing a PRIME to a ZOOM. Things WILL turn out in favour of PRIME. 70% of my shots are in Studio where i can control Light and prefer a system based around a CCD than CMOS. To be honest a Pentax istDS would suffice me here because i can add or remove light as i need. 30% of my shots are in complete darkness, since i do landscapes and do them at 2-4am. Don`t ask me how/why, this is my field. So my lenses need to be sharper than a tack and are all focussed around low light performance. Sorry guys i was rude anywhere. If i made a mistake please correct me. Cheers | ||||||||||||

Quote Back to 3 camera comparison. If someone showed me that clip and said, this is a comparison between 3 cameras that cost x, 2x, and 20X, I'd say no way. GH1 vs Red One vs Canon 5D Mk II footage comparison shoot out! - DVXuser.com -- The online community for filmmaking I did find the dpreview forumadvice helpful. Your mileage may vary. Quote Some P&S do indeed offer those modes but many people aren't aware that the degree of control offered is nearly abysmal. These people frequently come from the SLR world and know that having aperture priority means that you have plenty of choices from f/1.7 or f/2.8, say, all the way down to f/22 or f/32. So far so good. However, if the TZ7 had aperture priority, you would have from f/3.3 to f/6.3 at the wide setting and from f/4.9 to f/6.3 at the tele setting. Not much of a choice, isn't it ? Same applies to most other P&S, if not all. There's also the fact that with full-frame SLRs, depth of field is much, much less than with small-sensor P&S's for a given focal length and aperture. So you can greatly control DOF in an SLR by varying the aperture from f/2.8 to f/22, say. Not so with a P&S, where going from f/3.3 or f/4.9 to f/6.3 will do very little to increase or diminish DOF, which will always be quite extensive. That's why it is so difficult to get beautifully out-of-focus backgrounds (bokeh) with P&S's. In short, including a manual mode in a P&S is more of a marketing device than actually useful. It will do no harm, of course, but will do very little good. And nevertheless, you can mimic most of its functionality with the TZ7 by doing any of the following: to make it select a fast shutter speed, just use one of the Sports-type scenes and/or specify a fast enough minimum shutter speed (say 1/250). The camera won't then select any speed slower than this. Re: LX3's pocketability and ZS3's image quality?: Panasonic Talk Forum: Digital Photography Review Quote Of course it isn't. Actually, nothing beats the TZ7 (ZS3) zoom range for versatility, have a look at these two pictures I took with mine last summer, one is a 25 mm super wideangle shot, the other is a 300 mm super long telephoto shot, both taken within 5 seconds of one another. Try to do that with any DSLR, pro or not ! Re: Menus?: Panasonic Talk Forum: Digital Photography Review | |

Only real issue i have is with Dpreview forums and leica forums. Leica forums, anything other than leica is a crime and dpreview forums, well people spend 100K USD to get a dslr kit and store it rather than use it. Quote Back to 3 camera comparison.

I can argue about manual control but there is a reason why there is such a shortage for lx3 and its got nothing to do with supply and demand or panasonic controlling the supply. Its just that every dslr owner who needs a fast lens P&S wants it. Quote:
