2020 is getting closer every moment.  ;D

5D Mark IV will probably get compressed 4K resolution.

I had 15 memory cards that spans 1 decade. I have started to sell all of them to consolidate my cards to one 64GB capacity per body.

Reliability has improved so much that mishandling and misplacing these cards are more of a problem to me. Another problem is missing out on the decisive moment due to the memory cards filling up too fast or due to clearing the buffer.

My preference are 128GB cards but no one sells them for under-$150.

Buying a current MF brand is more feasible than Canon doing it from scratch. There is more money in Cinema EOS than MF.

If the next xD has CFast 2.0 then it probably will.

Based on your images and the images of others if I had the chance to redo the hobby again I would go with this instead.

It would mean an easier out.

Tripod Head

Tripod Legs
(BH says it's good for 500mm only but Gitzo says it's good for 600mm)

(BH says it's good for 600mm only but Gitzo says it's good for 800mm)

Above combination is very pricey but considering the 600mm is about $12,800 and does not include the body and other accessories attached then it becomes commensurate to the purchase.

A lousy tripod leg & head will increase the likelihood of garbage shots and an increase of preventable accidents. It will require extra effort & diligence to keep steady. If you value your time like everyone else then go with this combination. Trust me, you do not want to waste a weekend just because you can save $1000.

Another option to add is a replacement lens foot that affords a lower center of gravity and lighter lens. Just be mindful if the clearance for your fingers will fit your fingers.

Thank God it aint a Sigma. I'd get erectile dysfunction if you did.

240GB Crucial M500 with firmware MU03 on a 2010 13-inch Macbook Pro with Superdrive through SATA 3Gb/s (300MB/s) interface. Clean install of 10.9.1 + other updates. TRIM not enabled as it was recommended by a Crucial employee that the built-in Garbage Collecting is sufficient.

I was able to source a 2nd HDD bracket so I can make a Fusion Drive.

It appears that I may be in error. By using PCIe 3.0 overhead is largely reduced or even eliminated to allow for ~2GB/s.

But then again we are talking about a spec rather than practical application.

I just installed a 240GB Crucial M500 SSD onto a 2010 Macbook Pro with a SATA 3Gb/s interface. Feels like having a new computer all over again!

I could imagine how it'll be like with 10x or so faster data transfers. ^_^


My point is the transfer rate does not change. It is kind of like ethernet..... packets are sent at the same speed.... it's how many packets per second that gives you the transfer rate.  A fast memory card and a slow memory card both transfer data at the same block speed. A faster memory card is ready sooner with the next block and that's what makes it faster.

What people care about are read/write speeds. Rare if you ever see anyone talk about block transfers.

Yes but the transfer rate and the throughput rates are different. If we assume that they are using block transfers, the transfer rate is 2GB/sec. That rate remains the same no matter what the read or write speed of the card is....

For example, if the read rate of the card is 200MB/sec, the data is transferred in pulses of 2GB/sec... the line is only active 10 percent of the time. Get a 500MB/sec card and the data is still transferred in pulses of 2GB/sec, but the pulses are more frequent and the line is now active for 25 percent of the time.

Is the transfer synchronous (8 bits per byte and no framing) where 16Mbits/sec = 2Mbytes per second?
Is it asynchronous (8bits per byte plus 2 framing) where 16Mbits/sec = 1.6Mbytes per second?
Is it asynchronous block (256bytes of 8 bits per byte plus 8 bits framing) where 16Mbits/sec = 1.9998Mbytes per second?
Based on industry practices it appears that they are quoting raw throughput.

See explanation contained http://www.tomshardware.com/forum/271146-32-since#6004346

790-800MB/s is achievable using a PCIe SSD but no one can hit 768MB/s with SATA 6Gb/s SSD.

That is how I came about 1.6GB/s ceiling for a 16Gb/s SATA Express SSD.

I do not expect SATA Express SSDs that are below $1/GB @ 1.6GB/s sequential read/writes in 2014 based on this 2008 headline. It took them more than 5 years to get a $1/GB @ faster than 500MB/s sequential read/writes out the door. I would expect mainstream SATA Express SSDs by 2020.

Maybe by then 4K resolution *IPS displays will cost less than $1,000. The ones being peddled now at below $2,000 are TN displays.
