Wheater-sealed?

Click to expand...

They (irix) list this as being so when I saw it on their news feed. AFAIK all the cine housings are sealed to some degree, all the others are basically all dragonfly lenses with the odd blackstone/fireflylike the 11mm in a cine housing ie. gear rings installed and wider standard barrel width for easy swapping lenses without messing with follow focus rig positioning between lenses.

Whether the stills orientated blackstone models have better sealing vs cine I'm not sure since obviously stills dominant bodies have higher level of sealing vs true cine ones so lenses may follow that trend, either way some level of sealing is nice from the pov of dust and moisture but I'd not trust it in rain the way I may some stills market weather sealed lenses on a stills centric body.

Whatever it may be if most their other glass is anythign to go by this should be really good as their other stuff is pretty impressive if can get a good one (some models have alignment issues thus I'm currently after trying to find a good 15mm copy still as don't want to max out returns from same place constantly replacing to get a good one).

About 200 for me, but quite often less and only occasionally a little more, because I am not one of those people who holds their finger down on 20fps for every crow and pigeon that flies past.

I have long maintained that the number of shots is irrelevant; it's the time the battery lasts that matters. Rating by number of shots originates from analogue SLRs (and a small number of rangefinders) where the battery was only drained when a shot was taken and the shutter had to be controlled. It made sense to rate by the shot count back then. But then we added in auto exposure, then autofocus, then digital came along and brought with it auto white balance and image review, and now we've got mirrorless where the camera has to constantly generate a video feed and keep a high-refresh EVF rolling. Now the power used to capture a shot is essentially nothing in comparison to the power the camera is using just to stay on.

When I'm out in the field, my camera has to stay on all the time. It doesn't get turned off, it doesn't go to standby, and the EVF proximity detector is disabled; the viewfinder is rolling at all times. We don't get to chase down our animals here, you've just got to set up and wait, hope they run or fly past. With the skittish behaviour of most of our wildlife, those moments are over faster than the camera can start up. We're talking one second to actually spot the animal, another second and a half to bring the camera up, frame and hit the shutter, and then it's gone. If it's a peregrine hunting then you often don't even have time for autofocus, you've just got to pre-focus and hope for the best. So the camera stays fully on at all times. With mirrorless, that means a battery lasts about an hour and a half. In colder weather, which is more common here than heat, the battery has sometimes run dead before 60 minutes have passed.

This is why I'm still keeping hold of my 7D2. The 7D2 can last on one battery for two days of shooting. (In fact there was one time I accidentally left it on in the cupboard all week and it still had 40% of the battery remaining.) With the R5 and R6 I'm burning through at least three batteries every time I go out; in one instance I got through six in the R5 and finished the day with the 7D2 on my sole remaining battery. When being quick on the draw is more important than sustained fire there's no substitute for the readiness of the optical viewfinder, and mirrorless has many, many generations to go before it's going to compete in that regard. I prefer the R5 if I know I'm only going to be shooting for an hour or so, but for long days out, the power drain is simply too much.

If I was turning the camera off all the time or if I just plonked it on a table and held the shutter down, I expect I could get many thousands of shots out of a single battery. But that's simply not how shooting in the cold and dark here is.

Thank you for sharing!

there can't be a power limit like this. If I take pulse lasers, 1mW means not much as this could mean 1mJ pulse energy at 1Hz.
Suffice to say, this type of laser is unlikely to be irradiating the your typical environment, but with lidar, it is not necessarily continuous and therefore at least I can't make such a statement.

IMHO, eye safety (taking into account that people use binoculars, telescopes etc) would mean, that one can't damage a typical (silicon sensor) camera. But looking at the evidence... some of the LIDAR manufacturers and MANY of the laser-show-beam source providers do not appear to be taking their power and intensity levels seriously.

I'm really interested to learn if lasers that kill silicon image sensors can physically be truly legal! I would have the means to test and find out everyday, but I'm not going to irradiate my own camera and we're just too busy for me to tell one of my students to go purchase some used cams off ebay and do a series of tests. If I ever decide to allocate some play time to this, I'll post the results here!
It would make for a nice paper that would probably get cited tons though... hm

5D4 and R...where else has it been used?
In any case, it's a very good sensor.

Got my copy of this lens 10 days a go and got to test it out this weekend in Sequoia NP - Using the full wide angle to capture the big trees - SEVERE vignetting at 14-15 mm - any one elsce seen this or could this happen with a bad copy?

That lens requires considerable correction (by design). When corrected, the vignetting should be acceptable. The latest version of Canon DPP (4.15) has the corrections.

The fate of many camera stores was sealed with the advent of digital. In the pre-digital era, if you were a serious photographer you worked in black and white and did your own processing and enlarging. When I took up photography in high school I became a very good customer of one of the local camera stores in my hometown but I never bought a single camera or lens there. What I did buy were reams of photo paper, bulk Tri-X that I rolled into cassettes myself and lots of chemicals.

About 80% of the floor space of the store was devoted to darkroom equipment and supplies, with cameras comprising just a few counter display cases. Selling a camera was a nice bit of gravy, but the bread and butter were the consumables, which were sold to amateurs, professionals and commercial users.

Later, when I worked on a newspaper in a small city, we pretty much kept the camera store in business because of the chemicals, paper and other supplies we bought. They even delivered the supplies to us when we would call in an order.

Digital changed all that. That permanent, steady source of income dried up and camera stores in mid to small markets would never be able to sell enough cameras to stay in business. Online competition may have been the final nail in the coffin, but their fate was sealed once digital entered the market.

Ha...never thought about it until this thread, buy my hometown photography store was right next to the hometown newspaper. Location...location....

We are really describing multiple different business models. The first model being discussed is really mostly about printing and printing accessories, the second was to take advantage of the boom in camera sales during the analog to digital shift, and the third is a more sustained model based on much lower camera sales plus accessories.

What interests me most about this was that it is really the lost revenue from printing that doomed the hometown camera store. Following this line of thought, selling cameras was always secondary to the success of "hometown" camera stores. Now that "camera" stores are mostly dependent upon actual camera sales, that is a much smaller market and fewer stores can survive.

75 - 135 F2 where is it ?

After a week with the 14-35 it is already a love/hate relationship. The vignetting in the corners at 14mm is more than I expected. The weight of this lens in the pocket is a dream. I would love to hear a little more when you have done a photo walk with both the 15 and the 14 and what you like/dislike about both.

Today was the third 4 hour plus walk this week. I do NOT miss carrying the EF 16-35 on those walks.

So far so good, but I’ve not given it a good work out yet.
Sure hope Adobe gets a profile in LR soon since DPP has such an antiquated interface.

I didn’t charge the battery, but I did read up on the feature. It is a scaled down version of a feature from some earlier cameras. I was shocked to find that the T3i has just 9 autofocus points. I don’t recall having particular focusing problems, and that configuration sounds so primitive. It turns out that all ADEP does is to see how many of the spots covered by those 9 it can get in focus, and lights them up in red. Then for the shot, it stops down the lens as needed. The rest of the settings may or may not make sense. I can see why it didn’t catch on and why I forgot about the feature.

These days when lenses might not even have distance scales it is harder to implement hyperfocal distances any better than just eyeballing it.

Click to expand...

I have the distance bar enabled for RF lenses, that has been a great help. It even has a white bar that shows the useable range at that focal length for zooms. I'm consistently 10cm too close when using the 100-500 at its minimum focussing distance, the scale helps me to fine tune it after taking a step back.

I wish it would also work on EF lenses, but alas.

Yes, I know. But afaik you have to load it with card reader directly on the card not by cable. And I don't own a card reader neither SD nor CFE.

BTT: I bought a Sony though 128G to use with the R5. Had no lock ups or other problems with the card.

No laptop with a built-in SD card reader?

George Foreman might like it as well.

It's been reported before. However with more recent firmware the gains are only marginally better.

I agree. There was no new info in this video. Wait another few days and I am sure there will be many videos about the R3....

Can't wait for the r5c.

Yes, I would reserve one with Lens Rentals and then if the Canon store or someone else gets stock, you can always cancel the rental.

I’m just concerned as mine seems to moves more and make a slightly louder noise than the one I tried in the shop?

Click to expand...

Things wear over time. My RF24-105/4 makes more noise than the RF24-105/4 we have at work that sits on a shelf that everyone refuses to use.
Just keep an eye on it but if it really concerns you, take it to CPS.

No surprise considering the news lately.

Thanks for the feedback. So just confirming you are also on firmware 1.4.0?

If so I might bite the bullet and make the switch to the latest firmware myself.

Click to expand...

Yes. Firmware 1.4.0

I use 1/400s or faster and Iso 400 or 800. Aperture is set to f/2.8 or f/4.
If the light is good I first lower the Iso, second increase shutter speed.

An example I posted in the butterfly thread:

Thanks for your responses jd7 and RBSphoto. Rokinon is not available here in New Zealand and I don't want to buy offshore. My Samyang 14/2.8 was very sharp but the focus locked after a couple of months and was replaced quickly under the warranty. I don't want to have to deal with someone offshore.
I've come to the conclusion that, while this is an excellent, cost-effective lens, how long will it remain functional in the face of future camera firmware updates. A good friend had issues with a Sigma Art lens (35/1.4, I think) and with a Tamron 70-200/2.8 when she bought an R6. These problems were resolved with lens firmware updates. But how long will Samyang / Rokinon continue to support this lens????
Might have to stick with the EF 85/1.8 for a while as the RF 85/2 doesn't appear to offer that much more than the EF, the 85/1.2 are too expensive and bulky. Not sure I want to invest in a new EF 85/1.4.

On top of what is happening in factories...

It's natural to be impatient with manufacturers and retailers, but we are in some truly interesting times.
