EF 1.4x extender performance

I’ve read numerous reviews and opinions about extenders—some people love them, while others hate them. This note focuses on the Canon EF 1.4x Mark III extender, and it’s worth specifying that most of the negative opinions about extenders often refer to other brands.

The reality is that extenders require more light for autofocus to function properly. When it comes to sharpness, if you pair an extender with a high-quality lens and use a full-frame camera with good dynamic range, you likely won’t notice a significant loss in image quality.

A while back, I bought the Canon EF 1.4x Mark III to use with my Canon R7. Unfortunately, my experience with that combination was disappointing. The performance issues were so frustrating that I stashed the extender in my backpack and didn’t touch it for nearly two years.

Recently, after reading some new reviews, I decided to give the extender another chance—this time pairing it with my Canon R6 and EF 100-400mm Mark II lens. WOW! The results were incredible. Not only does this combination work exceptionally well, but it might even deliver sharper results than using the lens alone!

Here are some pictures taken this weekend in a very cloudy day using this setup.

ISO 12800 and after denoising the level of details is great.

The sharpness of this photo is just incredible.

R7 mechanical shutter failures

It appears that some users are reporting issues with the mechanical shutter failing in Canon R7 cameras.

In a post on the Canon Community forum, one user shared the following:

I joined an R7 group recently and there seems to be an ongoing issue with this model's mechanical shutter. The reports of MS (Mechanical Shutter) failures in this one group alone is unlike anything I've seen/heard before. Particularly for a cam that's only been around for 2 years.

Canon has not replied to this post yet.

Getting close

Some people think that once you get a zoom lens you are ready for wildlife photography but the reality is that even with zoom lens you need to get close to your subject to get quality photos. This vide from Paul Miguel is all about this topic.

Visiting Cuba as a Cuban Photographer, the risks

As a Cuban-American, I would love to photograph my country of origin, but believe it or not, visiting Cuba as a Cuban photographer is riskier than visiting as a photographer from another country.

As a Cuban photographer visiting Cuba, the primary risk lies in potential scrutiny from authorities, especially if you capture subjects considered sensitive by the government, such as military installations, police personnel, or politically sensitive areas. Photographing these is strictly prohibited and could lead to legal repercussions. Keep in mind that in most countries, you'll find signs indicating whether photography is allowed or not. In Cuba, however, such alerts are rarely present.

You can take pictures of police in public in the United States.
This is protected by the First Amendment,
which protects freedom of speech and the press no matter what nationality are you.

But things are not that simple. The level of destruction in cities like Havana is well-known. As a tourist, you might photograph the ruins of those buildings and face no issues. However, if I do the same, it could be interpreted as an attempt to document the destruction caused by the revolution. Being a Cuban photographer adds a political dimension to your work that photographers from other countries do not face. This is just one example of many situations that may seem fine, but may not be as acceptable if you are Cuban.

Here are the key risks to consider:

  • Equipment confiscation: authorities might confiscate your camera equipment if they suspect you are taking what is considered by them prohibited or questionable photos.
  • Harassment or questioning: depending on the location and situation, you might face questioning or even harassment from local officials if your photography raises concerns. I have personally witnessed this situation.
  • It's important to remember that even if you are an American citizen, when you enter Cuba using your Cuban passport, you are legally recognized by Cuban authorities solely as a Cuban national. This means that, under Cuban law, your U.S. citizenship is not acknowledged during your stay. As a result, the United States government is limited in its ability to provide consular assistance or intervene on your behalf in the event of legal issues or disputes during your visit. This distinction can have significant implications, so it's crucial to understand the potential risks before traveling.

I know of photography tour packages organized by Cubans living in other countries, and I can’t help but imagine what it would be like if you were on one of those tours and your Cuban guide got involved in one of these situations and was detained by Cuban authorities?

To be fair, this is not a situation unique to Cuba. Photographers from countries like China or Russia may face similar risks when photographing in their home countries. In such cases, local authorities often scrutinize photographic activities more closely, particularly if the subject matter is deemed sensitive or politically charged. For these photographers, their work can inadvertently take on a political dimension, making them more vulnerable to legal or social repercussions compared to foreign photographers capturing the same scenes. This highlights the broader challenges faced by photographers working within countries where freedom of expression and access to certain subjects are heavily regulated.

When living in another country, you become accustomed to your newly acquired rights and may forget that the freedoms you take for granted are not the same in Cuba or other countries. Always do your homework to avoid running into problems.

How much ISO is too high ISO

 I primarily shoot wildlife, and over the years, I’ve changed my shooting approach multiple times. Initially, I shot in manual mode, but I eventually transitioned to Aperture Priority or Shutter Priority. In both modes, I decided to leave ISO on Auto. This configuration allows me to focus on other aspects of photography, such as composition and white balance.

At first, I set the maximum ISO to 1600. Over time, I gradually increased it to 3200 and eventually to 6400. These changes didn’t happen overnight—it took years of experience, experimentation, and adjustments. During this period, I also switched between different camera makers and models, testing and refining the maximum ISO settings on each one. Today my R6 is configured with a Maximum ISO of 10200.

In my opinion, the ideal maximum ISO depends heavily on your camera and, to some extent, on your lens quality. A high-quality lens with superior optics produces sharper and more detailed images, which can help mask the noise that becomes apparent at higher ISO settings.

Modern cameras handle high ISO much better than the ones I owned a decade ago. That said, as photographers, we sometimes need to make tough decisions. Do you take the shot, knowing you’ll have to use a high ISO and sacrifice some sharpness, or do you let the moment pass? Ultimately, the choice depends on what’s more important to you: capturing the moment or achieving technical perfection.

Here are few pictures that I took today and where I had to choose between taken the shot or forget about it. These pictures are soft but to me they are good for Social Media. Can you guess the ISO?
