Quote from: crash-film on June 19, 2013, 03:06:01 AMand i got horrible writing speeds!!i have a komputerbay 32 GB x600 card and can barely top the data rate, that´s possible in the 550d.
Quote from: briwil on June 19, 2013, 12:04:42 AMCan anyone tell me, would a lens with Image stabilization help much?And what is this stuttering effect on panning shots, is that a result of FPS override dropping frames, or something else?
Quote from: savale on June 19, 2013, 08:29:54 AMActually I really like the 18-55 IS or STM kitlens. On a wider angle it's easier to shoot handheld. The IS will help!
QuoteQuote from: alexcosy on June 15, 2013, 04:22:37 PMYes i'm on a 5D2, you think it has something to do with it?I shot this morning 1880x800 2.35 @24p, and i can do it continuously.Seems like 1728x972 16:9 is ok too continuously.sould i send back and hope for a better one? i ve seen benchmarks up to 110MB/S but on 5D3, is it related?Don't send it back. It is definitely to do with the upper limit that you can write on the 5DMKII. When you run the benchmark you will most likely get a faster speed write but when you record you will see anywhere between 59 - 68 - 70MB/s sometimes mine goes above 70MB/s (briefly but its more usual to see it around 63MB/s)I have a Komputerbay 1000x 32GBSo what I am saying is that if you buy a faster one it is pointless because the 5DMKII will cap it by its bus limitation (unfortunately). The 5DMKIII has a higher limit and I don't know exactly what that is because I have no experience of them.« Last Edit: June 15, 2013, 04:45:24 PM by mageye »Report to moderator Logged
Quote from: Viente on June 19, 2013, 12:36:28 PMI wonder if there is anti aliaisng filter from other canon models which fits to 50D? Maybe from 7d or 60d? Does anybody knows?
Quote from: LEVISDAVIS on June 19, 2013, 10:35:44 AMHey Crash-Film... Got a response to your card write-speed issue.The math doesn't seem to add up when it comes time to how a card performs... Put a Komputerbay 64GB 1000x in a Canon 5DIII and experience 125MB/s write speeds. Place the same card in the 50D and experience approximately 70MB/s. The difference can be in the EXFAT format and the FAT32 format limitations. In addition to the card's read/write limitations, the camera also has it's read/write limitations. Thus, it's important to find the correct mate, if you will. The reason why the math isn't really panning out is because the camera is writing data at the very edge of it's capabilities. And since it appears that your card is pushing the edge of it's capabilities, in addition to your camera, you may be dealing with what may be described as a double-negative recording process. Try searching the ML forum and you might discover that the Lexar Professional 1000X and the Komputerbay 32GB 1000X, and the 64GB 1000X are the cards of choice. I can't write that for sure, of course. Myself, I've primarily been glued to the 50D Raw Recording forum and not so much the 5D II and 5D III. Anyway, the best value is probably 64GB 1000X from Komputerbay.... By the way Komputerbay has been quoted as stating, "We receive/sell/brand Lexar Professional's cards that didn't meet the highest, most stringent quality-control measures."Aside from that bit of re-assurance in the quality of the Komputerbay, having originated from a high-end compact-flash card manufacturer, I guess we're discovering that the Lexar 800 compactflash card is more of an entry level UDMA 7 rather than a high-end UDMA 7.You might consider turning off every feature not related to raw_record, and completely clear the screen of excess overlays, in addition, make sure you have all of your Canon menu settings for image & exposure set to disable. These are definite disrupters for maximizing raw_record.Hang in there and keep up with the posts. See you around. - Levi
Quote from: crash-film on June 19, 2013, 03:06:01 AMhi,i got my 50D now and i am a little bit disappointed.first of all: it´s dark outside, so there´s nothing to shoot.and i got horrible writing speeds!!i have a komputerbay 32 GB x600 card and can barely top the data rate, that´s possible in the 550d.to check if there´s something wrong with the komputerbay card i got me a lexar 16 GB x800.... and now:average write speed 41 MB/saverage read speed 100 MB/swith komputerbay:average write speed 26 MB/saverage read speed 63 MB/susing the W/R benchmarki use todays build. tryed different aligning settings. btw. if you set the sector sizes the same as the allocation sizes the cam dies.i had to remove the battery, start the cam with another NON ML card, restart it with an ML card.... and it worked again.used all the "tricks" ( raw off, noise reduction, global draw off/on...)but back to my problem. i expected specially with the lexar card a data rate of at least 50-60 MB/sor is this impossible with such a card?or am i the problem? to me it seems, as if write speed/read speed = 1/2 i expected a 2/3 ratio. at least from the x800 card.i have just a usb 2 card readersomeone any suggestions?thanks!!
Quote from: Viente on June 19, 2013, 02:05:37 PMI think maybe some kind of petition will push Mosaic Engineering to develop AA filter for 50D?
Quote from: rockfallfilms on June 19, 2013, 07:07:42 PMI emailed them 2 weeks ago and haven't heard a thing. Perhaps if everyone does it then we may get a response.

Quote from: LEVISDAVIS on June 19, 2013, 08:26:02 PM...Having said all of that, remember that each camera features an ability to shoot 1:1. At that point, every camera records with a pixel to pixel perfectly sharp image. I suppose the quality of the 50D and 5D II are similar to the upcoming Blackmagic Pocket Cinema Camera when shooting in a 1:1 crop mode. However, the BMPC camera will have a much newer sensor and will feature better high-ISO noise performance. Then again, it's 12-bit and not 14-bit video. Technically it may be possible to apply noise reduction to the Canon 50D and 5D II and have the same low-noise performance based on the extra information.
Quote from: necronomfive on June 19, 2013, 08:52:51 PMIt also needs to be seen if Black Magic will actually manage to get full 12-bit raw recording working on SD Cards. Currently, the BMPC "only" shoots 10-bit ProRes 4:2:2.Getting an BMPC suddenly doesn't make much sense to me anymore.
Quote from: briwil on June 19, 2013, 10:03:19 PMI'm not saying this is true, I really don't know, but couldn't one argue that the BMPC's 1080p ProRes is still better than 1536x864 RAW?
