I still have an EOS-3 that I bought brand new in 2002, & it has a roll of Provia 100F that has been in the camera now for 2 years, mainly because I only use it on sunny days. I only use my 24-105 or my 17-40 lenses right now with it - sometimes my 50mm 1.8 as well. I also have an Epson 4990 scanner that I bought about 7 years ago & it still works fine. If you scan your slides or negs, you'll need something to clean up the images because there is still some noise even in ISO 100 film compared to what I get in my 50D or my 30D. The EOS-3 is a Beast in my opinion & focuses Very fast! Enjoy it!

Yeah the scanning process can introduce noise. I wonder if stacking multiple scans can reduce the scanning noise? Im thinking the process would be similar to that used for astrophotography. Well i have some things to try.

I took it out this weekend and used it with my 600mm f/4L. I did notice that it focused very fast. I was surprised at the speed for an early 2000 model. Cant wait to finish up this first roll so i can see how it performed.

Nikon hasn't designed anything faster than f/1.4 in decades. Even the much-hyped 58/1.4G was not the Noct-Nikkor 58/1.2 that Nikon fans were dreaming of. It's rather ironic, considering how some of these old designs (Canon FL/FD 55/1.2, Yashica ML 55/1.2, Canon EF 50/1.0L, the Noct-Nikkor, and Minolta Rokkor PG 58/1.2) still perform admirably well and are coveted by today's photographers for their "look."

Click to expand...

Please correct me if I'm wrong but I believe I've read somewhere that the Nikon lens mount is too 'tight' (rear element cannot be large enough) for a 50 or 85mm brighter than f/1.4. Although that may be based on double Gauss designs, I think with retrofocus it should be possible to go brighter.

The flange and mirror box geometry for the Nikon F-mount is large enough to permit an f-number as fast as f/1.2, but no faster. The Canon EF mount has a limit of f/1.0. (Both rounded to the nearest 1/3 stop increment.)

Designs such as the Noct-Nikkor 58/1.2 and Nikkor 50/1.2 exist, but these are manual focus lenses. I suspect that from a practical standpoint, an AF lens of this speed is not possible for the F-mount, which is why none exist.

A few years ago there were some crackpots out there who argued (vehemently and endlessly) that this geometric limitation did not in fact exist, and babbled nonsensically about telecentric designs that could permit faster f-numbers. This is complete and total bull**** mentioned by people who do not understand basic principles of geometric optics. Others have argued that you could put a condensing group behind the lens to make the lens faster. Yes, you could do this, but it would (1) reduce the image circle, and (2) enter the mirror box. We've heard the news about the 4/3rds adapters that essentially perform this function: of course, it is possible only because the original lens was designed for a certain back focal distance, and on a smaller format mirrorless camera, there is sufficient space (and no mirror) to fit additional lens elements and no concerns about the reduced image circle.

If you decide to go with Canon, it might be best to go for the 600ex for future proofing.

I would like too, but that's not an option at the moment as I just bought a 70D three days back, and have a 24-105L to pay for in the next week. The more I read (B&H reviews) the more I think I'll probably end out with the Nissin!!

Chromatropic - great to get some data and many thanks. Is it possible/likely that Canon will produce a firmware update to "uncripple" the SD card slot? I already have UHS-1 SD cards, my bottleneck seems to be the older (legacy) 300x CF cards that I use. Anyway, many thanks for all your effort and for putting it into the public domain.

Click to expand...

This is likely a hardware thing. So it's not crippled, it's just the design at the time it was created. I'd be willing to bet that there's only 1 super-fast card 'port' on the DIGIC chip, and the other hangs off of essentially hangs off of the USB bus as a USB card reader, which basically limits it to 60 MB/sec theoretical max bandwidth, but because of the design age they only put in an SDHC (or was it SDXC?) which is the previous spec for SD cards which maxes out at ~30MB/sec theoretical performance.

As mackguyver put it, I'd bet that the camera pulls the RAW into memory, if it's supposed to write as RAW it generates the thumbnail JPG to write into the RAW file, and if it's supposed to write a JPG file it generates the JPG at the size & quality specified. At this point, it writes the file(s) out to the memory cards in parallel, and I'd bet via DMA (at least to the CF slot, which would help free up the CPU to an extent). At this point, if it finishes writing to the CF card, but the SD card is still waiting to finish it's write, it keeps that entire photo in memory (final output to both cards, so if JPG + JPG, the JPG for both, or if RAW + JPG, the RAW to the CF and JPG to the SD). So it essentially holds up a good chunk of your buffer while waiting to finish writing out to the SD slot. Once it's done writing that image, it clears out that particular images space in the buffer and you free up room for another photo in the buffer.

I think this is why, no matter what combination, continuous shooting for RAW+JPG is less than for just RAW. Both because of the extra CPU to generate the JPG, and the extra buffer space needed by the JPG.

And mikejkay, just go ahead and get a newer, higher speed CF card. You can get a quality Transcend 400x (90MB/sec read, 60 MB/sec write) UDMA7 compatible card for less than $40 from B&H. I've got them, use them quite a bit. Works great in my 5d3. It'll also just plain be faster than any SD card unless you regularly do a low-level format on the SD card as the UDMA7 supports TRIM, which lets the CF card clear out the blocks ahead of time instead of waiting until it actually needs to write to them.

I did some testing tonight and can confirm that the 5DIII is limited to 30MB/s - it's the same buffer depth as my 80MB/s card. 30MB/s is the max for Class 10 - UHS-I is the next standard, but the hardware likely wasn't available at scale when the 5DIII was designed. Fortunately the CF slot supports the latest UDMA7 150MB/s write speed cards!

Canon will be making a major annoucement at this show.

Click to expand...

No there won't.

Correct, there was no announcement as of yesterday. However, Canon staff claimed to "have not heard a single rumour about the 7D successor and couldn't see what the point of one was as the 70D has DPAF, better IQ and is only 1 fps slower", which sounded a bit suspect. It wwould have been more convicing to say that they had heard the rumours, but had no idea of specs or delivery as HQ hadn't told them anythig.

Hey ho

Yes Canon is very sucessfull and know what they are doing. Thats why they dominate. Why would they come out with a really good mirrorless and I know they have the technology already. It will canabilize their sales on the DSLR market specially the Rebels.

Click to expand...

Why? Because otherwise Sony, Fujifilm, Panasonic, Olympus and all others will cannibalize their Rebels and all of their other DSLRs with the possible exception of action-oiented models (1D-X)? ;D

Click to expand...

They haven't so far and growth in mirrorless in at least two major markets has reversed.

That's not to say that there's no future for mirrorless, nor that mirrorless isn't the future, just that it doesn't seem to be the present. Why would Canon and Nikon risk undermining their supremacy by bringing out 'pro' mirrorless cameras? Isn't that effectively endorsing their competitors' efforts? If Canon and Nikon dump their legacy mounts, what competitive advantage do they have over the likes of Sony or Fujifilm?

I think that's the crux of Canon's current dilemma. They didn't want to rock the boat by developing mirrorless, but evidently elements in their hierarchy felt the need to enter what was a growing market (hence EOS-M and Nikon 1). Now that the growth has died, so has Canon and Nikon's enthusiasm for their mirrorless systems.

Who knows how this will end up, maybe EOS-M will develop into a fully fledged system (especially if there is room for a full frame sensor in the specification), or the EF mount may start to evolve towards going mirrorless. I suspect that this isn't fully decided at Canon and will depend on what happens in the market this year.

Personally my feeling is that reduced flange distance on FF is simply much less of an advantage than on ASPC since your having to deal both with larger lenses for a larger image circle and long lenses to avoid more extreme light angles.

I think its notable that both Canon and Nikon have put most of their focus on FF devolpment over the last couple of years, more levels of body on offer and a lot of new lenses on offer whilst EF-S/DX lenses have been limted mostly to kit updates.

To me it looks like theres a real divide in the mirrorless market between east and west, in the former ultra small view finderless bodies make up most of the sales, in the latter theres a much smaller market focused on higher end bodies with viewfinders. My guess is if Canon come up with a higher end ASPC body then it will be released in the west.

As luck would have it the MagMod gel holder I ordered arrived recently; the band holds tight to the flash and the gel holder seems solid on it. The gels seem easily scratched but I doubt that can be helped, worst-case I can bond some gel film to a thin oiece of glass or whatever. It is much easier to change gels with it compared to Canon's somewhat awkward holder. Photos later if anyone is interested.

Good stuff ! I'm highly interested in your experience with the MagMod, it looks awesome.

I'll try for next week; I'm fully occupied until then but I'll be in better shape afterward.

Interesting lens. I ran it up against the 24-105L and they are almost identical. I was looking for something light weight for hikes or a lens for the "to go bag". I bought a SL-1 for my pole cam and that little camera is actually quite impressive. Maybe the 55-250 might just do it. The price is right, that's for sure.

tiger82 · Mar 3, 2014

I sold my 7D and got a 70D plus $200 cash during Christmas when the price was $949. Here's what I got: noticeably faster AF for sports so fewer OOF shots, better high ISO performance, articulated screen eliminates the need for my angle finder so I can shoot lower to the ground or above my head and still compose, articulated screen can fold to protect itself, silent shutter, and I can use the same batteries as the 7D and 5D2/3. Here's what I gave up: 0.5fps, snob appeal of a semi-pro body, weight, and weather sealing. All in all, my keeper rate has substantially increased.

I have a hard time seeing Samsung as one of the smaller players. Maybe not so big in photography yet, but it'd be foolish to bet against them. They might not go after the pro market, but possibly pretty much everything else. Time will tell.

Click to expand...

I think I would generally agree with this. Right now they're a smaller fish. But Samsung is willing to manufacture in numerous mature markets. I would expect their camera market share to gradually grow over time, especially at the entry level in the nearer future. The recent Canon announcement to exit low end cameras should benefit them.

Yes - I meant that Samsung were currently a smaller player in the camera industry. Overall, they have a stated goal of becoming the largest manufacturer of retail goods in the world.

Hi Guy,
I stored mentioned lens with hood attached as I rarely put it down. Today I decided to pack light but stayed surprise as I was not able to remove hood from lens. In the end I managed with applying some force, but another surprise came as I m not able to attach it back in regular or reverse way.
Did you faced any similar problem?
What could the solution be?

Thanks

Very interesting article. 360 TB WOW That's a lot. Thanks for sharing.

I remember wire-wrapping 8Kbyte memory cards to replace the obsolete 1Kbyte ferrite bead cards on the mainframe

and how excited we were when hard drive prices dropped below a dollar a kilobyte ($9,995.00 for a 10Mbyte drive)..... we have come a long way.

I was hesitant to make a comment here, but things seem to have calmed down a little.

I do a lot of Macro, albeit it's all Underwater Imaging, I have two set ups for Underwater.

1DMK IV in a Seacam Housing, I find the APS-H format just get's me closer and for my Macro Imaging works better than anything else I've tried (FF/APS-C), primarily it allows me to better utilise the 100f/2.8 Macro L IS.

For everything else I use the 5DMK III again in a Seacam Housing, FF seems to the wide angle Imaging better than the 1.3 Crop of the APS-H format.

For me - shooting underwater macro - I am very happy with my 7d + 100L - (granted the 1d series + housing is a little out of my price range)

The reason I like aps-c is because of the greater working distance (not always necessary) but there are some shots I am sure I couldn't get on full frame underwater (and there is no port for the 180L on my ikelite setup).

I do plan to put together a FF rig sometime soon, but I will keep my 7d mainly for underwater macro.

Just my opinion in regards to my shooting.

Thanks Edward. If we don´t have more solid info of a high MP Canon body before this summer, I think I have to get one and try. It seems to me it will make manual focus a bit easier and it is also a bit tempting to try out the sensor. My use will be slow and non-action photography with the TS-E lenses and the two Zeiss lenses I have, so some of the speed issues you have will not bother me much. I am a bit puzzled over the lack of lenses for this body though and I am not overly enthusiastic over the need for the adaptor.

Hi Eldar, the Metabones adaptor I have is the EF-E Mount Version III, make sure if you get the Metabobes you get the version 3.

It's actually not much of a problem, as I only have Canon Mount lenses the Metabones can stay on the a7r except when I'm using the Zeiss EF 35, I have not noticed any degradation of IQ using the Metabones, but I have to assume there is a small amount.

And your right, if you keep your Imaging to slow/static action the a7r is a pretty reasonable Camera with a very good sensor, plus the cost of the a7r has made it attractive, especially now, I think the a7r can be purchased for a lot less now than when I purchased it in Late December 2013.

Mt Spokane Photography · Mar 2, 2014

In what country?

You can get one from Canon, but its a bad idea. They must be shimmed or selected to match the extender, just a 1/10,000 inch out of true will affect the image.

Send it to Canon to have it replaced if its damaged.
