Camera Lens Prime/Zoom Dataset

Dataset summary

This dataset contains physical and design specifications for 35 Sony camera-lens models. The binary classification task predicts whether a lens is prime or zoom.

Focal length is intentionally excluded because it would directly reveal the target.

Collection

The specifications were compiled from official Sony E-mount lens support pages. They are published manufacturer specifications, not physical measurements made by the student.

Features and target

Field	Role
`diameter_mm`	Continuous feature
`length_mm`	Continuous feature
`weight_g`	Continuous feature
`filter_diameter_mm`	Discrete numeric feature
`aperture_blades`	Integer-count feature
`label`	Binary target: 0 = prime, 1 = zoom
`source_id`, `model`	Identification metadata
Augmentation and parent fields	Provenance metadata

Only the five feature columns are intended as model inputs.

Splits

Split	Original rows	Synthetic rows	Total rows
`original`	35	0	35
`augmented`	0	350	350

Split	Prime	Zoom
`original`	18	17
`augmented`	180	170

The original split contains real product records. The augmented split contains synthetic variants only.

Augmentation

Augmentation method	Rows
`bounded_relative_jitter`	175
`same_class_local_mixup`	175

Bounded relative jitter: diameter and length change by at most ±2%, while weight changes by at most ±4%. Discrete specifications and labels remain unchanged.

Same-class local Mixup: each lens is mixed with nearby lenses from the same class. Only diameter, length, and weight are interpolated. The primary parent's discrete specifications and label are retained.

Intended use

This dataset is intended for educational tabular-classification, data-validation, and augmentation exercises.

Limitations

The dataset contains only 35 independent Sony lens models, so it does not represent every brand or lens category. The 350 augmented rows are synthetic variations, not additional commercial products.

For augmented rows, model identifies the primary parent; the synthetic measurements should not be interpreted as official specifications for that model.

Synthetic rows should not be treated as independent validation or test observations.

Ethical considerations

The dataset contains public product specifications and no personal or sensitive information. Sony names and model identifiers remain trademarks of their respective owner.
