The Best and Worst of 2025

Agreed. I am dubious of price points being used in this fashion…price is a completely subjective metric and does not in any way speak to technical achievement or generational improvement
If the Nikon Z5iii gets the nod over the Canon R6iii because of ones favors "value for money" over "overall specs with all the whistles and bells" that premise should be applied to lenses as well. In that case, the 45mm F1.2 should be favored over the Sony 50-150mm f/2 GM. Don't get me wrong, the Sony lens is absolutely great, but I just don't get why in one case "value for money instead of overall specs" makes the decision and in the other category it is the opposite.

The 45mm F1.2 brought together two things that I´ve never seen put together: F1.2 and cheap (or at least affordable). That imo is an absolute game-changer and easily the best "value for money" this year concerning lenses.

Oohhhh, that sounds great!!! Enjoy it and have some fun. And maybe, just maybe, post a nice wintery pic here :)

Here they are :cool:

Being fair isn’t being a hater. Canon Rumors actually has decent writers, not merely blind fanboys.
I often find that Canon Rumors (CR) writes better than Sony Alpha Rumors (SAR) even for Sony gear, which is commendable for CR and laughable for SAR. Heck, a friend of mine, who is a Sony user, enjoys more reading this website than theirs, because the writing is clearly more responsible and mature here.

For this article, specifically, I think Sigma deserved a few recognitions, but that’s all I have to say.
Yes and so is the community here.

TL;DR: the Z5 II is a great camera unless you use it for a use case it was not made for.
WOW. Somehow I think I could say the same for most cameras….
Yes, but there are guys who recommend this camera exactly for wildlife, here is an example
I was running into that trap because I hadn't much time to make decision, and I already ask my wife to trade it in for a real camera such as Nikon's highly praised Z9. She can afford it.

I own it and many other L series RF lenses, and I think it's useless

I would take a 1.4x compatibility any day over it
Interesting. I still use my old EF 100mm f/2.8 L IS USM (not yet upgradet) and I never missed that it can't a 1.4x TC, but I use it quite frequently with extension rings to get closer for more magnification...

Can't watch YT videos at work :cry:
If that's what they recommended then I would discount them as a trustable source of advice...
But generally speaking, I'd consider wildlife the realm of any camera system's top offerings a priori, if budget allows.

That's the thing, yes. Even if being done optically, it's still stretching. Some defend adding, for instance, an extra lens element to straighten the image.
Will that extra element lead to a softer image? Perhaps.

Lets get it right: optical correction is not stretching. The goal with optical correction is to try and ensure that as many individual photons are distinguishable as possible when hitting the thing capturing the image. You can't stretch a photo to make it hit two pixels instead of one, but what you can do is try and ensure that two photons on very similar trajectories hit individual pixels on the sensor.

With firmware/software stretching photon strikes that didn't happen have to be invented.

I've suggested before that you refrain from engaging in technical arguments, and you repeatedly fail to heed that advice. Optical correction is bending light, and that is not without consequence. While you are correct that a single photon cannot hit two pixels instead of one, a picture is not generated from one photon. Light from a point in space can certainly be bent in a way that more than one pixel is hit, in fact that's the basis of chromatic aberration, as illustrated for lateral CA here:

Like geometric distortion, CA is something that is easily and routinely digitally corrected.

What about photon strikes that are in the wrong place? I mean, many ultrawide zoom lenses that fill the corners still have 3-5% barrel distortion. Do you turn off all distortion correction in your images (along with CA correction), so that they remain 'optically pure'? I doubt it.

While optical correction is bending light, you don't disagree with the statement that optical correction doesn't stretch light. Arguing about bending light is a bit pointless because that's the whole point of a lens - to bend light such that it lands on the sensor.

Some lenses deal with this better than others. Some subjects are impacted by this more than others. Measuring CA is what a lot of lens test websites do when they shoot specific subjects to measure lpmm, etc. Your generalizations here are no better than mine.

Let me make your day: I don't use distortion correction when processing images, I can't even remember when I last used CA correction.

How do you process images? Do you use jpegs straight out of camera or do use RAW? If you use RAW, how do you convert to jpegs or TIFF or whatsoever to view them?

I can see where you're going. What's the point of your question? To try and turn me into a liar because CA/LensCorrection is being done implicitly without me being aware of it? That's a disappointing angle to take.

The point of the question is to lead to a discussion of what happens when we process RAW data and the choice of RAW converters. If you are unaware of your software doing correction, then how on earth could that make you a liar? (Lying is deliberately telling an untruth.)
