Same here.

If I have to decide the topic is more important to me than the gear.

Maybe I should use crossposting to increase my # of posts here

I am completely surprised that the 85 SP does not get more accolades. It is a marvel of a lens, I liken it to my 135 f/2L. The color, the contrast, sharpness and amazing AF speed and accuracy for a 3rd party lens. If the 35 1.4 is better as they say, it will be a giant slayer (EF 351.4L ll)

I have both the Tamron 45mm and 85mm 1.8's and they are razor sharp and awesome lenses. Both are my two main primes and the 45mm is almost always on my main shooter. It would take a lot for me to replace either one.
The 45mm is so good I'm not even interested in Tamrons new 35mm. My 45mm turns into a 35mm simply by taking two steps backwards! lol

ADDED: Plus I wouldn't want this new 35mm simply because it doesn't have VC.....

Sorry, but I think DXO testing isn't even worth a single comment.
We all know the RF 1,2/50 is a fantastic lens, so, why care about DXO ratings?

Do you own the lens? Still not a lot of especially helpful sample shots easily found on web.

Thanks!

Ok then I will not modify the sharpenss in the EOS R menu. Thanks!

To put it in as simple terms as you can understand: a GaAs "pathway" is only 3 times as fast as a Si "pathway" of the same size.


The maximum GaAs wafer diameter actually available on the market is 4".

But keep dreaming.

Somewhere below the speed of light is the intrinsic limit to electrical conductivity (i.e. some atomic level energy transfer function in a physics lecture which I can no longer remember!) Obviously you know something about electrical engineering way beyond my level, but a waveform is a waveform is a waveform!

It has a peak, a crossover point and a trough! The amplitude (Y-axis) and horizontal spacing (X-axis) between those is the definer of a logical ON or OFF. A given clock speed is only an indicator of how many of those peaks and troughs I am counting in a second to form a SERIES of bits which are concatenated to form a user-definable set of bytes and then aggregated into commands and data values. Ergo, the higher the clock rate the more commands/data I can fit (minus ECC/CRC/etc.) in that time period. A Two Terahertz clock speed is NOWHERE NEAR the limit of energy transfer within an electrical conductor which forms the basis of a waveform. The only issue is inherent noise floor which makes it tricky to figure out where "bitwise packets" begin and end, the higher the frequency you go! It's a processing of creating high purity traces that don't block as much energy transfer OR allow a more discernable series of "pulses" to be passed around.

Again, I'm NOT an electrical engineer so I don't know much at the truly low-hardware-level of HOW they do that sort of DSP to be able to discern and cleanup an electrical signal that has 60 Billion and Two Trillion pulses a second! THAT is a level of electrical hardware engineering that is TRULY WORLD CLASS !!!!!!!!!

This company has THEIR OWN wafer making capability in BOTH CMOS and GaAs and GaN. It's 200mm by 200mm chips!
I see them every day! TOO BAD SO SAD !!! They ABSOLUTELY HAVE the Quality Assurance technology to ENSURE line trace integrity and doping quality over that large of a substrate! I should note that to etch a chip that size on an Ion beam/Electron Beam etcher is a SLOOOOOW process which is WHY only 1400 of each type of chip has been made! Think of etching rates that says it takes OVER A MONTH to make each chip! Think of how much it costs to buy enough etchers to take over one year to make a mere 2400 chips. I think they actually BOUGHT the entire company so they could force all etcher production to be sent to the parent company! Hint: It's a lot of money! Think of the automated and customized optical scanning technology they had to buy to do quality assurance on that large of a wafer!

In research labs, I've seen researchers that are doing 600 mm wafers in CMOS now! GaAs and GaN is not that far behind at that 600mm size! You've been living in a cocoon! You probably subscribe to Electronic Design and Microwaves & RF magazines !!! Goto some of the symposiums listed therein! It's here NOW! 80 GHZ and 100 GHz is nothing these days! Two Terahertz is starting to mature out of the labs and 4 THz is coming online soon! Go fully opto-electronic and we are into Petahertz+ ranges! This is NOT NEW NEWS !!! Read up on it!

And I should note the designs are PARALLEL and Synchronized so that numeric, string or pixel data gets processed on a specified time schedule and then the results are pushed out within predictable time period for external workstation-level processing/visualization. We care about GROSS AMOUNTS of data packets being processed in parallel on a specific schedule. We don't actually NEED linearly fast individual bits/bytes processing just massively parallel SYNCHRONIZED processing! Remember! We are outputting image tiles that are 128-bits per pixel (RGBA + metadata channels) at 65,536 by 65,536 pixels in size to be filtered and presented on a 64-bit RGBA colour laser projector that can do up to 10,000 fps to visualize neural tissue interaction in real-time!

WE are the ONLY ONES in the world that can do that sort of processing in real-time! Ergo, the parent company built the world's FASTEST supercomputer and LARGEST 64k by 64k resolution multi-RGB-Laser projection system with completely in-house custom-built GaAs 60 GHz and 2 THz clock speed super-chips!

Not even the NSA/DARPA has THAT sort of compute technology!

It's here NOW! We have it! Deal with it!

Only you know what you are supposed to get excited about. How is anyone else supposed to know? Careful of the carpet. Don't wet yourself, Skippy. You weren't waiting for this and aren't a buyer anyway, right? So no point.

How about an RF mount combo digital sensor/film body? That's one no one has asked for...

I am in limbo waiting for a "new" M system camera to come out. The current are a bit long in the tooth (except M50).
I can't afford to buy a new one next year just because the 'aggressive price and features' makes the next Mxx? way better than the M50 I bought this month.
Same goes for rumoured updated M-lenses. There are some good EOFY sales on now, so I was considering buying a lense at least.

Click to expand...

My two requirements for a new M were "Hot shoe", "No EVF" and "Eye AF". But I now have an RP to use for macro with flash, so the requirements are now just "Eye AF" and "No EVF". I hope the Mxxx version is good enough and cheap enough so I don't have to pay a lot after selling the M50.

I'm still hoping for a revamped original M, that one was built like a tank.

Thats normal and its worse for big lenses. If you look at the back of your lens where the lock pin fits, its a oval and not perfectly round. Its done that way to handle tolerances, and depending on how the two parts match up, there may be some play. Don't worry, its normal.

maybe the industry is slow as shizzle. we barely get big technology breakthroughs but they still charge a lot for cameras. cellphones are evolving by the second especially on the photoside and it isnt all about sensors. its about software ans sensors and options/features.

Possibly, but it's very unlikely. Especially considering it's 720p. Not a lot of people use the 120fps from the R, but it is a high bitrate and actually looks decent upscaled to 1080p. If they did every update it with AF I would probably use it more.

Click to expand...

Exactly, I like the quality of images it produce even in 720P 120 fps that is totally usable to upscale in 1080P. I just wish that they update AF in that mode

so far, there has been no evidence that ef-rf adapter affects image quality of adapted EF lenses used on R-series cameras. not a slight sign of vignetting levels being affected by the adaptor.

Planning a trip. Will be trekking in Northern Scotland and trying to limit weight on my back. I know I could carry a point and shoot but then I come home and don't like what I see on my screen. So, I usually resign myself to bringing the 5D4 and some glass. On past treks, I've limited what I carry and often missed my 100-400 when coming across birds and other critters. This time, I am really thinking I'll carry the Canon RP with the RF 24-105. But, will prob also bring the 100-400 with the EF-RF adapter.

Now, the next dilemma is "stability." I usually don't carry a tripod, again because of weight. Been able to make due with high ISO, leaning on trees, placing camera on a rock, etc. But then I had an idea. I have RRS "Pocket" pod / head (TFA-01 Ultra with BH-25 Pro). I took the RP with adapter and 100-400, put it on the tripod and head using the lens foot, and tried it. Remarkably stable!

Think I am going to use this kit. RRS specs are, in my experience, conservative. I know this is not a replacement for my more substantial tripod and ballhead but some support is always better than no support

Thanks for the thoughtful review. Interesting about the dust problems.

circle of confusion is then aperture or magnification?

Click to expand...

The acceptable circle of confusion for a particular use case is determined by the magnification involved in that use case that occurs between the image projected by the lens onto the imaging plane and the final display size viewed from the final viewing distance by a person with an assumed acuity of vision.

That is, the circle of confusion is an expression of how large a blur circle projected onto the imaging plane (sensor or film) can be and still be perceived as a single point by a viewer of the final image after enlargement to the display size when viewed from the intended viewing distance.

The diameter of the blur circle is defined as a linear measurement on the imaging plane, but how large that linear measurement may be (and thus the maximum acceptable size of the blur circle projected onto the imaging plane that we define as the circle of confusion) is determined by the corresponding angular size of such a blur circle when enlarged in the final display size and viewed by a person with a defined visual acuity at the final viewing distance that will still allow that blur circle to be perceived by that viewer as a point.

People missed the point of the story. Camera market is a tiny byplay in Sony business. What they really are trying to do is strengthen their lead in image sensor business.They don't care of Canon or Nikon at all, they just want them to use Sony sensors. Their real threat is here:
https://www.dpreview.com/news/91435...ony-reach-1-in-the-global-image-sensor-market
I'm not even sure if they are really interested in taking over diminishing traditional camera business, they would have already bought Sigma or Tamron to create lens repertoire that would be as pervasive as CaNikon's.

Why would you limit your analysis to a few months? Would you project net worth by looking at it the day you get paid and the day before that?

I'm looking forward to the RF 70-200mm - f/2.8

Here is what I think about this lens: The best 24-105mm lens ever. Definitely. I used Canon EF 24-105mm f4 L IS USM, Sigma 24-105mm f4 OS, Nikon 24-120mm f4 VR and Sony 24-105mm f4G OSS. This RF lens is the best overall. Optically it is very balanced and I can use it at f4 without even thinking on EOS R. Only above 90-95mm at f4 you'll see some decrease in corners and vignetting at 24mm at f4, and that's all. CA is very low, it is always sharp in the middle section and it is really good from 24mm to 90mm at f4 from corner to corner, it is short, handles perfectly well and the control ring is a God-given I wish it had close-focus like EF 24-70mm f4L IS USM (which I'll sell tomorrow) but you can't have it all I guess
Canon has a winner. Definitely. Now it's time to give new buyers a reasonably priced 24-105mm f3.5-5.6 IS.
Edit: I see a lot of vignetting between 24 and 35mm at f4 in RAW (uncorrected). Compared to my Sony 24-70mm f2.8GM this is very visible (GM lens is probably the best 24-70mm anyway and it is more than 2 times more expensive than Canon). After I edit RAW file and with some sharpening, you will still have good corners. And remember this is at f4.

Sounds like a miserable guy to me. I find copulation to be a wonderful thing.

Xeens are cinema lenses. They're made by Rokinon, but are a little higher quality.
