Today, we’re diving into a head-to-head comparison between two popular choices: the Canon EOS 90D with the EF-S 18-135mm f/3.5-5.6 IS STM lens and the **Canon EOS RP with the RF 85mm f/1.2L USM lens**.
This comparison isn‘t just about specs; it’s about understanding the strengths and weaknesses of each setup, helping you decide which one aligns better with your photographic goals and budget.

The Contenders: A Brief Overview

Canon EOS 90D with EF-S 18-135mm f/3.5-5.6 IS STM:

• A versatile DSLR: The EOS 90D is a powerful APS-C DSLR known for its high-resolution sensor, fast autofocus, and impressive burst shooting capabilities. Paired with the EF-S 18-135mm lens, it offers a wide zoom range suitable for various subjects, from landscapes to portraits.

Canon EOS RP with RF 85mm f/1.2L USM:

• A full-frame mirrorless marvel: The EOS RP is a full-frame mirrorless camera that excels in low-light performance and image quality. The RF 85mm f/1.2L USM lens is a prime lens renowned for its exceptional sharpness, beautiful bokeh, and fast aperture, making it a dream for portrait photographers.

Image Quality: Full-Frame vs. APS-C

The EOS RP, with its full-frame sensor, has the edge in terms of image quality. Full-frame sensors capture more light, resulting in cleaner images with better dynamic range, particularly in low-light conditions. The RF 85mm lens further enhances this advantage with its impressive sharpness and shallow depth of field.
The EOS 90D, while using an APS-C sensor, still delivers excellent image quality. The sensor is capable of producing detailed images with good dynamic range. However, the full-frame sensor of the EOS RP offers a noticeable improvement, especially when printing large images or cropping heavily.

Autofocus: Speed and Accuracy

Both cameras offer impressive autofocus systems. The EOS 90D boasts a 45-point all cross-type autofocus system, providing fast and accurate focusing across the frame. The EOS RP utilizes a Dual Pixel CMOS AF system, which offers quick and reliable autofocus, especially when shooting video.
The RF 85mm lens on the EOS RP benefits from the advanced autofocus technology of the RF lens system, making it incredibly fast and precise for capturing sharp portraits. The EF-S 18-135mm lens on the EOS 90D is also capable of quick and accurate focusing, but it may not match the speed and accuracy of the RF lens.

Versatility: Zoom vs. Prime

The EOS 90D with its 18-135mm lens offers greater versatility due to its zoom range. This lens allows you to capture a wide variety of subjects without changing lenses, making it ideal for travel photography and everyday use.
The EOS RP with the fixed 85mm lens excels in portraiture. The 85mm focal length is considered a classic portrait lens, known for flattering perspectives and beautiful bokeh. While it’s less versatile for other subjects, the exceptional image quality and sharpness make it a top choice for portrait photographers.

Performance: Burst Shooting and Video

The EOS 90D shines in burst shooting, capable of capturing up to 10 frames per second with continuous autofocus. This makes it a great choice for capturing fast-paced action.
The EOS RP also offers decent burst shooting capabilities, but it’s not as fast as the EOS 90D. However, the EOS RP excels in video recording, offering 4K video at 30fps and full HD at 60fps. The EOS 90D also offers 4K video, but it’s limited to 30fps.

Ergonomics and Design: DSLR vs. Mirrorless

The EOS 90D is a traditional DSLR with a deep grip and a viewfinder that provides a clear and bright image. This design is familiar to many photographers and offers a comfortable shooting experience.
The EOS RP is a mirrorless camera, featuring a compact and lightweight design. Its electronic viewfinder offers a high-resolution display with real-time information. The EOS RP also features a tilting touchscreen, making it easier to compose shots from different angles.

Cost and Value: Balancing Performance and Budget

The EOS 90D with the EF-S 18-135mm lens is generally more affordable than the EOS RP with the RF 85mm lens. This makes the EOS 90D a more budget-friendly option for those looking for a versatile and capable camera.
The EOS RP with the RF 85mm lens represents a premium investment. The full-frame sensor, exceptional lens, and advanced features come at a higher price point. However, the image quality and performance of this setup are exceptional, justifying the investment for photographers who prioritize these aspects.
