Pentax vs Sigma Colors

That would likely explain it. A good chunk of the center of that cow photo is dark so the camera was likely thrown off. on that same photo, had you used multi-segmented, you might have not seen that.

When it's happened to me, I've been in the middle of a shoot and can't stop to experiment, but I am almost sure it's happened to me while using spot metering or when using center-weighed and shooting into dark clothing. I don't think it's ever happened using multi-segmented metering.

As someone who has both the DA* 16-50 and Sigma 24-70 EX and 70-200 II, I can tell you I've experienced first hand the random overly-cool-temperature photo from all three lenses, in studio and out on the field.

What metering mode did you use for the uber-cool cow pics?

Lens hood for 24-70mm f/2.8 IF EX DG HSM

As I said, was hoping B&H would have it too as I'd rather buy everything from one place (i.e. you guys) than put a small order through Sigma :-)

Thanks though!

Wondering if B&H sells the original hood for the 24-70mm f/2.8 IF EX DG HSM. Left mine at a job site somewhere. :(

I am purchasing a lens or two in the next few days and would love to buy the replacement hood through BH instead of from Sigma direct (rather get it all in one place).

Selling Guest Portraits At A Wedding...?

I doubt anyone would want a vendor to start selling product at their wedding. Would be like the DJ charging for song requests.

I think the best option is to offer it the same way photobooths are sold - bride/groom pay for the service and guests can use it for free. You can offer it as a package - include a certain number of prints, use it or lose it.

Take the pledge - No new Pentax lens purchases

Pentax has every right to ensure that vendors are not cheapening Pentax product by selling near cost just to push volume. Problem here is that this is quite a sudden change for us. Perhaps Pentax should have introduced this policy only with new products, then gradually applied it to existing product.

That said, Apple users have been used to this kind of MSRP death-grip pricing policy since the early years... all of us who have ever purchased anything Apple know full well not even WalMart is allowed to sell more than a few bucks below the Apple store price. You seldom hear Apple users cry about this hard fact. Yet we still buy iPhones, iPads, iPods, Macs, etc.

Lenses for a wedding?

Camera Lens Rentals is a great place to rent from. Top quality product - they obviously care about their equipment as every time I received a lens from them it looked to be in mint condition.

As for shooting with the 50 or any other prime, I typically shoot with 2-3 bodies, so I can keep a lens on a body (particularly specialty lenses like a fish-eye or wide angle). If you don't have other bodies, I'd think carefully about which lens will become your primary and when will you need to switch (based on type of venue and the events taking place). This would impact your lens selection process. However, don't underestimate your distances. A 50mm can be extremely limiting when you have 100 people crowded around you.

I'd stay far away from variable aperture lenses. All super zooms - i.e. the 18-250, have variable apertures and for typical indoor venues, where lighting is typically focused/limited/poor, the last thing you want is a variable aperture lens messing you up as you zoom in and out.

Based on the venue as you describe it, the 100 Macro will be of limited use as well. Perhaps good for a few long shots from the back of the venue (assuming you can get enough distance), maybe some macro shots, but that's likely it.

For the wedding ceremony itself, the DA*50-135 (f/2.8) is a great lens to shoot with. I'd team that up with the DA*16-50 (f/2.8) to cover the lower range.

For the reception (assuming dancing and other typical wedding happenings), you should likely stick to wide angle lenses. I typically use the DA*16-50 and a Pentax DA12-24 or similar.

I use the AF540 - great flash, great features, definitely NOT the flash to use without plenty of practice time.

Should I upgrade my 28-70 EX DG Sigma?
Posted By George Lama

It would matter which body you send. In my case, my K5 and K20 are the same when it comes to lens calibration. When I calibrate my 16-50 on one, I end up doing the same to the other with good results. In my case, I sent my K20 as the K5 is my primary.

When the lenses got back, I did more testing using the K5, and with zero adjustments they were spot on.

They also upgraded the firmware on the lenses, which included the AF data). As a bonus, now both lenses are properly identified in Lightroom :-D

Have you calibrated your lens to your camera?

I own the newest versions of the non-OS 24-70 EX HSM and 70-200 EX HSM II and wasn't too thrilled with them out of the box. I attempted in-camera calibration as I did with my DA*16-50, but there wasn't enough calibration available that would work for the two Sigma lenses.

So I sent both lenses to Sigma (along with one of my Pentax bodies) for calibration. What a difference did that make!

Calibration might be worth looking into before dropping money on a replacement lens. Instead, you can then buy a prime lens or a wide-zoom and add to your arsenal.

Dust vibrations?

Very big difference between the "drop a quarter to make the bed vibrate" K10 to the lesser (but faster) vibes of the K20, to the almost imperceptible K-5 chirp.

If you do the cleaning in a very quiet room, and you stick your ear to the rear LCD, you might hear a very distinctive, high pitched chirp.

Did you mistakenly rename DNG files as JPG? Perhaps this is why LR is having problems with this - it's expecting a JPG, but they're in fact DNG?

The biggest difference you will notice will be due to processing processing power and memory, followed by increased speed of hard drive access (IDE versus SATA, or faster SATA, plus increased cache and buffers.

Video cards will not have as much an impact unless you're pushing by working on rather large files. Many on board video chips have plenty of RAM and power for most uses. Doesn't hurt to have a dedicated card though.

K5 to K10 comparison
Posted By George Lama
Replies: 23

Having the K10, K20, and K5 in my bag, I can certainly point out that for what you're doing, the K5 is a huge upgrade based on wide ISO range, Higher ISO IQ, faster shutter speed (1/8000 versus 1/4000), and 7 fps (more than double the K10's). There are other features though that you may enjoy too, such as the full HD video mode and if you're into it - in-camera photo processing (HDR and a handful of digital filters) just to mention a couple.

I for one know I can capture sequences with the K5 that were downright impossible before :cool:

Lightroom clone/heal touchups - need some help
Posted By George Lama

I'd have to disagree somewhat with the statements about Adobe wanting to keep features out of Lightroom purposely so as to require us to purchase PS. That would be like claiming Microsoft is keeping features away from Excel so we can't do PowerPoint presentations with it.

By the same token, you could say that Photoshop should have all LR features - after all, you're paying very good money for it, about US$900 if you buy retail, so why not include it all?

That said - I do 99% of my post in LR and do agree that there are some PS-type tools that would be of benefit - like magic eraser aka content aware editing. But primarily, for my workflow, I want LR and PS to remain kings or queens of their own editing domain :-)

Info about modeling photography, agents, etc.
Posted By George Lama

To the OP - are you in direct contact with the agency? I didn't gather that from the posts. If you aren't, bypass the mom. You need direct contact with them to ensure you are getting all the right info. Also, this could result in possible future work for you, so why not cultivate that relationship?

As to the copyright/limited use licensing:

If you display your images sans watermarks, whether online or via printed proofs, you can't prevent someone from stealing your images. Screenshots, taking a photo of the screen, printing the page and rescanning into the computer... I've seen it all and some people don't seem to mind how horrid it looks.

Sadly even in this high-tech era, watermarking is your only real safety. Should they grab your image, recrop it or downright attempt to erase your watermark, you have evidence of their actions.

As to those stating their images were stolen by others for newsletters and websites, you can do a couple of things - depending on whether you think these actions would negatively impact your business or not and depending on how far you're willing to take it:

1) send them a bill for the stolen images, with a limited license release stating they have the right to use images x, y, z for their newsletter/website once they pay. In your bill, place a note stating that you saw them using the image.

OR the more aggressive alternative:

2) Not much you can do about a self-distributed newsletter other than perhaps a cease and desist order from your attorney, followed by a bill as stated above.

For the one who used it on the website, send a letter/email to the hosting provider stating the image is yours and is being used without your consent. The DMCA makes it easier for webhosting providers to pay attention to us. And again, a bill to the client stating if they pay, they can continue to use the image as needed.

Again - make sure you understand the impact either of these actions could have on your business.

For a lens separation issue, I'd definitely go direct to Sigma corporate. Sending it anywhere else will likely mean they will in turn either ship it to Sigma or have to wait for Sigma to ship parts to them.

I'd say skip the middle-person.

Laptop specs for running LR3
Posted By George Lama
Replies: 27

If you're working in LR with RAW files and plan on working with large catalogs:

The more power, the better. Dedicated GPU is a definite plus.

The more memory, the better. LR will use a lot if available. Even with 8 GB, I feel it could use more.

The faster the hard drive, the better. If you're keeping your cache on the C: drive, you definitely should look to get at least a 7200 RPM drive. For external storage, and again, if you're working with RAW, you will want an eSata connection for the best performance.

Second monitor has nothing to do with whether the GPU is dedicated or not. All laptops can run their internal monitor plus an external. With a real docking station if available (not a USB docking station), you can run two external monitors instead.

i5 versus i7 - depends on which processor you get. There are low and high end i5 and i7 CPUs. Match up a high end i5 and a low end i7 and you might not notice a huge performance difference.

Sigma lenses calibrated to a body

I agree. Interestingly, both my Sigma Lenses needed beyond -10 on both my K5 and K20. Now that Sigma calibrated the lenses to 0 on my camera, if I needed to do micro-adjustments at least it would be within the range offered by the cameras.

Per my work order for both lenses, firmware was updated plus adjustment of AF Data was performed.

I can use my 70-200 in my small studio. Usually at 70 and while standing by the door :-D

You can do a lot in Lightroom, so it depends what you mean by "what pros do."
