What Autofocus settings should be used with back-button focusing?
Posted By FrankC

My preference is to use continuous focusing when using the rear focusing button. This is so that if and when I do need continuous AF, it's always available. I have never experienced a problem focusing on a static image while in continuous AF mode.

Eyesite affects manual focus

Which body are you using? Not all bodies have removable focusing screens, but I'll assume you know your camera has this capability.

Getting a split focusing screen could help; it's worth a shot since they're not that expensive in the first place.

A tip on using the diopter. Make sure that your eye is relaxed as opposed to trying to focus near/far.

Vertical grip

I mainly use my 645D on a tripod, so having the vertical grip isn't a huge need for me. However, with that said, if Pentax had designed an external vertical grip for it, I'd get one. Personally, I feel that for the price, the vertical grip should have built into the body in the first place.

No vertical grip and the dark frame after a shot longer than 30 sec are really the only complaints I have with the camera.

Macro extension tube or a bunch of uv filter rings to fix focus?

Instead of buying a bunch of UV filters, you could go to a plastic shop like Tap Plastics and have them cut you a piece of plastic tubing. Or what's even cheaper is to go to a home improvement store and buy a short piece of PVC pipe and paint it black.

Thank you SininStyle so much for the articles. They are exactly what I was looking for. The Z97 with the 4790K currently sells for about $520 at newegg, while the i7-5930K alone is $580. Add in a decent motherboard, and you're near a $1,000.

So it's pretty much a no brainer in terms of value, the Z97 is the clear winner. However, the i7-5930K using the X99 chipset will have USB3.0 and USB3.1 ports, and more PCI-Express slots running at 16x than the older Z97 chipset. Plus the Z97 chipset is limited to only 32GB of RAM, while the X99 can use up to 128GB. And based on the RAM article, more is better; especially with files over 1GB.

If the price was about the same, I'd certainly go with the X99 system. But considering what I'm using, either of the two would be a massive improvement.

thanks to everyone who replied to my question.

Thanks, SininStyle


Yeah, I had read somewhere that Skylake is just around the corner. The extra $30 for DDR4 ($95) vs DDR3 ($65) does not matter much to me. It's the cost of the X99 MoBo+CPU which can be around $800 - $1,000 alone vs going with an Z97 board and chip for around $500. Either system will blow the doors off (or should) my LGA775 system.


For those who don't know, the Pentax 645D that I use produces files that are between 225-250MB when opened. So, after stitching a few frames and then copying those in separate layers in Photoshop, things get huge fast.


Benchmarks for Photoshop are often synthetic and not using real-world files. Most show no advantage of using more RAM, but then again, what's the size of the file that they're coming to this conclusion. Obviously if comparing the speed of 8GB, 16GB, and 32GB of RAM on a 40MB file should show no speed improvement, but using a 6GB file should show something - or at least I'd like to think so.

Yes, I completely agree that 6 gigs of RAM isn't enough. I'm going to get 16GB to start unless anyone knows that going with more will be a benefit. My files often exceed 1GB in Photoshop. I don't do any video editing.

Just wondering what type of computer are those who process files from the 645D/Z are using?
I'm currently running an LGA775 Asus mobo with a Q6600 2.4GHz, 6GB of RAM, a GTX570 graphics card, and a Samsung 840PRO SSD as my scratch. While many things are acceptably fast now that I've upgraded from XP to Win7 64-bit and added the SSD, other tasks are painfully slow. So I'm looking to upgrade my motherboard, CPU, RAM and graphics card, and I'm not sure if the Z97 motherboard with an i7-4790K is plenty good, or if the performance increase with an X99 and a i7-5930K along with the DDR4 vs DDR3 memory is going to be significant enough to make it worth the extra dollars of investment.

What are you guys/gals using? And if you've upgraded, then from what to what, and what has been your experiences?

Thanks

HELP Choosing Trigger For 645D
Posted By FrankC
Replies: 10
Views: 1,358
I went with a $20 Vivitar wired trigger. I skipped the intervalometer versions since that feature is in body, and I've yet to use it on my 3-year-old body anyway.
Be prepared to have to modify the wired remotes if you buy a non-Pentax version. The generic versions FOR Pentax all have a plug that's too big to fit into the hole in the 645D:hmm:. I had to use a bench grinder to reduce the outside diameter of the head of the plug to get it to fit inside the hole. That wasn't a problem as there's plenty of plastic around the plug so I didn't have to worry about exposed wires.

645Z and ColorChecker
Posted By FrankC

When I use the software with files less than 40MB (closed) it works, but the two files that are at 67MB (closed) failed.
The other common thing with the 40MB files is that the color checker was a fairly small portion of the overall image. With the files that are failing, I got in very close and filled the frame with the color checker.


So it would appear that the easy fix is to just not get too close to the color checker.

This is odd. I've tried to make a profile using a DNG taken at ISO1600 and slightly underexposed and got the "insufficient memory" error. I then tried to create a profile using an image that I've successfully made a profile in the past, and it worked. There's something going on with the high-ISO file...

Well, I used to be able to use the CCPP with file from my 645D without any issue, but now it's giving me insufficient memory errors. Not sure what happened, I'll have to contact X-Rite support. But before I do that I'm going to uninstall/reinstall the software.

If you purchased your batteries from a drug store, they could be dead out of the box. Take the camera to a local camera shop and have them check out the camera and the battery.
I used to work at camera shop and would get people all the time who bought a battery from the local drug store that day and it was dead even though the package said it would good for years.
Buying the battery from a camera shop will ensure that you don't buy one that has been sitting on the shelf for a few years.

I have successfully used Visible Dust fluid and swabs. But quite frankly, I think it's all a bunch of massively overpriced stuff. .8oz of fluid for $22 and it says that it contains isopropyl alcohol. Well, heck, I get a 16oz bottle of 90% from Target for about $2.
The swabs are nothing more than pec-pads on a plastic stick.
They do work, but I can't stop feeling like I've been taken by their pricing.

Now if Metabones would only make a Speed Booster for the Pentax 645, then that lens would be even more of an attractive buy.
I asked them in an email if they had any plans to build one for the 645 and they said no, not at this time.
Maybe Pentax could design and build one of their own? I know I'd jump at the opportunity to get one.

Focus Points?
Posted By FrankC
Replies: 7
Views: 985
The choice of focusing point depends on your subject and your shooting style. Most people (beginners to pros) it seems prefers to set the camera for only the center focusing point.
This allows you to know and pick exactly what will be in focus.
If you're shooting something like birds in flight or breaching whales where the subject could be anywhere in the frame and at a moments notice, then a multi-spot setting would be beneficial.

Is it worth investing in Pentax and K-Mount?
Posted By FrankC

1.For me, I would base my buying decision on the body and lenses available, as it seems to be what you're doing. If Pentax offers the body and lenses that you want now and in the future, then I don't see why not to go with Pentax. However, if I was looking for a system that used Nikon's 14-24mm, I just might go with Nikon instead.
I get your point about the lenses being too slow, but take a look at the offerings from Nikon and Canon that are faster. Are you willing to pay the extra costs for a faster lens. If so, then maybe Pentax isn't right for you.

2. I have to disagree with your statement regarding the AF not being fast. Fast enough for what? I used to have the original Canon EOS-1 back in the late 80s and it was faster than what I could ever do manually. The current Rebel is far more advanced and faster than then top-of-the-line EOS-1, so I don't put a lot of value into statements that claim this body can AF faster than this one. They are all very fast. Where I do put a lot value is the body's ability to shoot at a frame rate while continuously AF.
and the most important point
3. Pentax seems to be economically weak. Yes, they certainly appear to be very limited as far what new product they're introducing. You also have to think about the smart-phone affect which has decimated the point-and-shoot market which is where the big brands got much of their profits. Canon's latest body, the 7D Mark II is their first new body in 2 years, and it replaced the 7D Mark I that introduced 5 years ago. So I think the strain on the market is being felt by all brands and not just Pentax. However, since Pentax has such a small market share, the effects on them may be far more detrimental.
